How Trees Bring Water
Permaculture Instructor Andrew millison explains how trees are connected to water in the atmosphere as well as water flowing through the landscape. This video articulates the amazing role that trees play to ecosystem and climate health, and how their removal causes the drought-flood cycle.
There may be some questions about the scientific validity of the concept that forests attract rain. Here are a number of peer reviewed scientific articles to support the hypothesis which suggests that forest cover plays a much greater role in determining rainfall than previously recognized. They explain how forested regions generate large-scale flows in atmospheric water vapor.

Another important concept from the video is that condensation and evaporation in large areas of forest causes moist air to flow to land
From the abstract of the article below: “ Intense condensation associated with high evaporation from natural forest cover maintains regions of low atmospheric pressure on land. This causes moist air to flow from ocean to land, which compensates the river runoff….High evaporation and large extent of natural forests guarantee both a stable and high throughput hydrological cycle. Forests protect a continent against devastating floods, droughts, hurricanes, and tornadoes. Sustaining natural forests is a sound strategy for water security and climate stabilization.”

I have changed the title of this video from "How Trees Make Water" to "How Trees Bring Water". I still support the idea of trees "making" water available in the landscape. The second definition of "make" is: _ 'cause (something) to exist or come about_ '; bring about. But my use of the word "make" was distressing to many people, because trees don't actually construct water molecules from Hydrogen and Oxygen. And the point of this video is really to encourage the planting of trees as a tool for climate stabilization and landscape rehydration. Because Trees Bring Water :-)
Looks like he was attacked by the pedantic society. haha. 😂
Thanks ❤️🙏🙂
Yet, plants do create new water molecules too. They use the H in water from the ground and the O from air C02 and combine them into water vapour. So we are not, in fact, drinking dinosaur pee ’distilled over and over’. The atoms are recombined (but to know that we must use the complete photosynthesis equation, not the simplified models)
One immense effect of condensing of vapor to the atmosphere explain by physical chemistry. While vapor is condensing, it create contraction 270/1 time of an empty space or vacuum and create none stop chain reaction of air flow in which carried vapor and condense continuously. Similar phenomenon take place in Polar zone where strong airflow is naturally move through out the year.
💯
I'm from southern India. Over the past 3 years I've planted 500+ trees on my 4 acre farm.
This should be part of every grade 3 curriculum when talking about the water cycle, amazing. Still learning and changing my view of the world after 40 years.
Respect to you, keep on being curious
Along with gardening, farming & the rainforest.
My thoughts exactly
Andrew, there is one seldom explained effect that you didn't mention. Besides trees, a well formed forest also contains a stratification of intermediate species, the layers of mid canopy, understory and ground covering plants. Stratification within a well formed forest system with all it's layers creates a temperature gradient with higher temperature within the high strata in the top of the trees down to the cooler temperature in the understory, and the coolest temperature in the lowest ground cover layer. Since cool air is denser, that temperature gradient creates air flow downward through the different strata with air flow eventually reaching the ground. As air cools, it tends to condense water on leaf surfaces in the lower strata, further contributing to water capture beyond what happens in the upper canopy you describe. Even underground, the fungal web can absorb humidity directly from atmosphere, if the soil is permeable and aerated. This means that not only are condensed water droplets absorbed, but also invisible water vapor can directly get into the soil. One reason why this is so important is that if you compare an unstratified monocultured forest to a fully stratified forest, the stratified forest will exhibit the above described phenomenon while the unstratified forest will exhibit the opposite. In unstratified pine or eucalypt plantations without understory plants, the net moisture flux will be negative because no downward airflow occurs.
Wow, thanks for that. I had never heard that before. Great info!
amazing comment, deserves a pin in my opinion
Wonderful comment! 😃
Thank you for this comment i learned even more
What @thechief762 said is exactly right. The coastal temperate rainforest was broken by us clearcutting all the old tree canopy, all the flora and fauna below....if you look at the NW Cascadia forests you see that climate crisis is Big Oil and clearcutting all our cousins that helped create who? You and me. I think the conclusion of this video is the heart of the problem. We have the illusion we are separate from Mother Earth. In real time it takes centuries to grow forests we have cut down, plunder the wonder. But we can stop cutting down the Amazon, stop cutting the remaining old growth in BC and Alaska. And build a restoration economy that is premised on first do no harm, returning to an indigenous way of seeing the world. Trees are cousins. They breathe out, we breathe in. Trees are our family, not a source of pulp. Break through the misperception we are separate from Mother Earth. One simple way is to begin having conversation with trees, reanimate your relationship with all plants and animals. They aren't silent, we just stopped listening.
This is the first time I realized how the channels in the bark on some trees act as small canyons for water and nutrients to travel down to the roots. Incredible.

This is a phenomenon that I discovered whilst camped in a tree house. 🌳
@@tylerk.7947 and sometimes children stuff coins in them :(
This is true. I've seen it happen with an extinct volcano in our area. 200 years ago they cut all the trees away and the lake dried up. Then someone discovered an old painting of the volcano and surprised to see so many trees there. They gave the volcano land back to indigenous people and they replanted with native trees. During the last 10 years I have seen the lake fill up. The bird life that has come back to the sanctuary and the Wildlife in general is incredible.
Where is this?
@@nickbono8 replanting of the forest at Tower Hill Victoria Australia. There would be an article about it on it on the net.. 👣
so nice to read
@@vinodsagardarbare1187 and also very nice that you enjoyed the read. 💦 I drove past top of the Volcano this morning and the lake is full. We are in the last month of summer here, hottest month of the year. After the water in trees came back to life at Tower Hill, I saw agriculturist Peter Andrews talking about Natural Sequence around 10 years ago. He had an 8 acre project and brought back the water. He has some good stuff on Swales as well. This video here would be great as part of school curriculum in the environmental studies area🗝
@@ralsharp6013 2 hours from me, might drive out for a visit with the kids. Do you know if you can kayak on the lake?
I grew up in Germany, where we were taught about the beneficial effects of trees and rain 60 YEARS AGO!
These are important lessons, it would be helpful if they were incorporated in basic education in USA also.
I was surprised and delighted by just how many forests there are in Germany...even in cities! It's beautiful.
Through domestic birth rates and brining in cheap labor from Turkey and other countries, in those 60 years Germany's population has grown by tens of millions of people, totally negating the chance for the country to produce as much oxygen as it uses in metabolisms and combustion. The German forests are token nature, not real nature, as in all of central Europe. Germany could sustain a human population of 20 million, but 70 million heavy consumers of animal products is an ecological disaster.
wilhelm reich in the 1940s created a simple device that controlled the weather. it is just a bunch of long copper pipes (6-8) that are grounded and point towards the sky. it only had 2 settings, 1 attract clouds until it rains, 2 disperse clouds until the sky is clear. depending on weather condition it took up to a week to see results. on a weaker level that is what trees do.(bring rain)
@@brusso456 simple, effective, experiment. Thanks.
“Go plant some trees”. Done… but never finished. 💚
I've never heard such a clear explanation of this process. Each day that goes by, I'm more and more convinced permaculture will continue to transcend politics and save the world.
As we spread that vision, so it will be!!
Delusional. The vast majority of people don't give a shit. We're headed for extinction.
I wish saving the world is the final part of the story. Unfortunately it is not!!! You will get colonized and enslaved and then divert the attention of your mind to serve those people and they use it to create a fake paper currency to rule over them and create a new language out of stolen languages and then destroy the countries and then lecture those descendent of same enslaved people in this new language about what they just discovered and educate them about the benefits of tree and water I really wish the story ends after saving the world!! But there is no end to anything just like there is no beginning to anything. You never get to see the end of anything!! Because the story continues and life continues in other forms. A beginning in our human definition is just your starting point of knowledge of something. If you begin a step before beginning thats where a new beginning of yours starts. Similarly, an end is just your last piece of information you have unlocked. Fortunately universe runs a computer program called "karma" which will reverse the actions taken by humans onto themselves to balance the universe
Hello!! Well said 🙌
The point you make at 4:20 is probably the most important of all of them. These raindrop nucleation centers are SO critically important. Another great example of this is when you have very very pure distilled water and cool it in a freezer to below freezing. It will still remain as a liquid until the water is shaken, then it instantly freezes. I'm sure most of us have experienced this. This happens because the very pure water doesn't have many nucleation sites to start (nucleate) an ice particle in the water. It's a bit of a different example, but just one that many people may have tangible experiences with. Similar things happen with very microscopically flat pots and boiling water well above boiling point before it boils. Then all of a sudden it flash-boils and can explode on someone. This happens often with microwaving water in a really smooth coffee cup. Trees creating nucleation centers for raindrop formation is so critically important. I didn't think you'd mention it, and I was going to come here and mention it, but I'm really glad you did, and makes me respect you even more as a fellow scientist/engineer.
ANd it seems that forests that are antrual and old can organize themselves so they liberate all those particles and evaporation at the same time, something that random planted trees can't.
This is very good at explaining the role of trees in the environment. It's hard to understand why farmers around here seem to hate trees, cut them down, and burn them. Most don't even harvest them for lumber or fuel.
jesus, where are you that farmers are doing such stupid things? 😳🙏🏼

@@jayejaycurry5485 Wretched.
It could simply be to get a few more acres of crop land, and also it takes less time to drive / operate equipment the full length of the field, especially for those switching to larger automated driving systems. However, many probably don't realize the moisture benefits of large quantities of trees.
On top of that, the shade from a tree reduces evaporation and creates a micro climate that can be noticeably cooler. 🌳 Thanks for the great video, you are great at sharing knowledge!
and on top of that also water does not mix with water of differing temp's and water does not compress. so the water that goes underground will slowly come to the temp of the water already down there force the water already down there to move along. eventually finding its way to outlets we call springs. the tree's act as insulation getting the ground level to a temp close to 4 degree consistantly will enable a natural spring as opposed to a seeping spring.

The cutting down of the trees is what’s heating the planet, NOT CO2!!!!!
When I was a kid we would drive 20 minutes to my aunts house. Around her home there was farm land, and the Ri Grande. We could feel the humidity and temperature change because we had the windows down. We also had a lot of huge old trees, and grasses lining the Rio Grande. Some group of people decided that taking out the trees would conserve water😏🫣
I hope your aunts land was left alone! And I hope too that the people learned otherwise. Have you shared this and other permaculture videos with the people of that area? That would help a ton, sharing the knowledge.
@@louisegogel7973 she had nice home with huge yard next to farm fields. And my family and I have fished all along the Rio Grand during the 80’s and 90’s. We remember what the banks of the river use to look like before they destroyed a lot of the trees, and vegetation along the river. There is less and less farm land now so after I got out of the army we would drive out there and the air temperature change between the city and the farm was not as dramatic as it use to be. I’m just a regular person I don’t have a channel.
Thank You for this great information. When I was younger back in the 60's and 70's I was a logger in northern California and i started noticing that the amount of annual rain fall started to decrease, at this time I started to wonder if the reduction of trees in the conifer forests had an impact on the rain and now I see that it does, I also think that clear cutting was a big mistake.
Just wonderful! You confirm something I use to say in my speeches: "the mountains and hills are the water tanks of Nature". Thank you very much.
I watch this video couple of times and this is really great. I am living in California and we need more trees, plants. I do view that if someone can grow plants in the undeveloped areas and make a small pond and grow plants, it would bring the whole area from desert to forest.
A fantastic example of this is San Francisco's Golden Gate State Park. It was all sand dunes but now it's a lush landscape.
I’m pleased to report … I just planted 3 trees this week 😊 … 2 Moringa trees and 1 Avocado tree. 🌳🌳🌳 The weather report said 5 days of more or less consecutive rainfall (we are in SoCal)(it’s Feb 2). So the trees went into the ground the day before the rains 😊 🌧🌧🌧🌧🌧
i love that trees make their own rain. i was doing groundskeeping at a lighthouse in maine for a few years. the spruce trees used to create rain from catching the mist coming off the sea. it was sunny but a full rainstorm just under the spruces. it was so incredible to learn about in person without a single word spoken. spruces are ugly as piss though LOL
Absolutely spot on !! Very well explained & nicely illustrated too. Planting trees is definitely the solution for preventing drought and fixing soil conditions as well as bringing & retaining water & moisture within the soil structure. I like that your conclusion is to go and plant trees, particularly starting near the coast and working with nature to bring water further inland helping to prevent drought and deserts areas forming. I understand this fully and have been planting trees recently in the UK, England, Cornwall. I have planted many native trees and will continue to plant many many more…🌱 Trees also soak up and store co2 & release oxygen in return which enables life to exist. I have been planting common alder this week which also helps to fix nitrogen back into the ground. There are so many benefits that come from trees and woodland areas. They provide shade, habitat, leaf matter, as well as the roots and all life that exists around it helping to nourish and aerate the soil. If you take a tree, plant at least two to replace it. Well don’t stop there, simply keep on planting more & more trees. Work with nature and become a part of it. Personally I find the whole process of planting trees extremely satisfying & rewarding… 🌱🌱
A million times THANK YOU for this video. I don't understand why this exact messaging isn't being put forth by large environmental organizations with this level of detailed explanation. It's not enough to say we need to plant trees, people need to understand the why. But maybe even more than that, people need to understand how we got here, and that the land around us wasn't always the way it looks today. Since the Bronze Age, our ever-growing population has needed trees for warmth, food, housing, tools, boats, furniture, and especially industry. Can't fire pottery and melt metals without burning trees. Weapons, cookware, food storage, canopic jars, glass, artwork, jewelry, just about everything an archeologist might dig up got there with the help of trees. Multiply that by 5 thousand years and by now 8 billion people who believe the human race cannot survive without enough toilet paper and Clorox wipes, and it's no wonder we're in crisis. THANK YOU.
Can anyone recognize the fact the trees and water are healing substances .
Beautifully done. I did a ground water course and they talked about trees only as a loss of water from evapotranspiration. I thought, “you guys have missed the most important bits, the infiltration etc of the trees and vegetation.” And too often I hear people wanting to clear vegetation to reduce flooding. You really explained it well and beautiful drawings.
It takes a special kind of stupid not to realize the vegetation has adapted to and has adapted this planets climate to suit its needs.
My grandpa, the farmer, has a major vendetta against trees because they "steal the water" from his productive crops. Being raised to believe this I'm still struggling with this concept and am really thankful for this video!
@@ashleyhurley9795 I'm a former pesticide applicator, and "the book" says that "weeds" will "compete" for nutrients from wanted crops such as lawn or turf grass. As a home owner, I know now that clover brings nitrogen to the lawn, and even weedy flowers are bee food. The best pasture land is near the edge of a forest. A field with one big tree in the middle is fine. Rows of trees planted as windbreaks are good. The soil you save is worth more than the tiny amount of crop space. I cringe when I see farmers till their fields into dust storms. That dirt is money!
True, I've seen over clearing of 'weeds', and it doesn't help
Just revised my Saturday tour to include the "pond" created by our agroforest. Since we are directly on a limestone plateau without naturally occurring ponds and lakes.... drains too fast....this is a powerful anecdote. Also including taking temperature of the ground from parking lot to shaded agroforest with ground over. 6 different stations. Tropical notes, we do not have fog ever, we do have 90% plus humidity all year round. The tree roots on our coral limestone plateau spread out laterally beyond the drip line. Especially toward rain barrels and raised beds, hopefully we are far enough away from house drains. We make peace with that.
Thank you 🌲 I've been trying to express this to people that are being told to cut the trees on their property down, to abate forest fire.
As a woodworker/ tree guy I can tell you that trees often have 200-300% moisture content in that their structure holds multiple times of water by mass compared to their dried weight.
i think its meant like 50% of the trees volume
Peter Wohlleben talks about this in his book ‘The Hidden Life of Trees’. It blew my mind. This video helps visualise the same concept. Hopefully this teaches many people the importance of trees, forests and ecosystems. Thanks for the video! 10/10 👍🏽
I’ve literally just read that chapter, weird
@@mrjf5249 It's a good book!
Permaculture makes me hopeful about the future. These videos are great to explain to everyone with eyes to see why trees are so important. If you plant trees with edibles for humans it becomes a win win win for humans, nature and the many creatures we share our planet with. Thank you for making and sharing these great videos. I will do my best in spreading this information in my networks to get the information as far out as I can help with.

In my area the council only plans inedible trees on the street curb. They should chop them all down and plan fruit trees such as mango, apple, pear... instead. The tree will provide green as well as fruit for the passer-by pedestrians as well as food for wild life such as birds, possum, bats.. and possibly rats. Also the laws should be amended to release council responsibility if pedestrians get food poisonings from eating the falling fruits. It's a win win situation.
@@JohnNy-ni9np you know they don’t want to deal with cleaning up the fruit and leave on the ground. They are even thinking about getting rid of them completely and replacing them with algae tanks
@@noblood6137 Also kids will climb up the tree to pick fruits, then get hit by the cars running beneath, thus laws should be amended so the council should bear no responsibility as well.
@@JohnNy-ni9np there's social complication with planting edibles trees in the city street. in less fortunate area, ther possibility of social conflict may helped Poor ppl would fight for the edibles to eat or sell. There must be rules & regulation but it will eat the already bad city budget.
So impressed with this video, and happy to hear it. Yes, I'm planting trees, and I support those organizations who do as well. When I see countries investing in tree planting programs, like Iceland or Scotland, it really makes me happy. I've read that North Africa used to be green, with trees, lakes, not a desert at all, and Babylon too. All over the world, where trees were removed, the land suffered, and then the people suffered.
Your Videos are super educational, they should be shown as teaching in schools worldwide in each year.

Grow them from seed and plant them in the area where you live. I've started and plan to make that my legacy for my hometown.
This video was so well put together. You are a fabulous teacher for such an incredibly important subject. Over the past two years I’ve planted several trees on my tiny little property. I’m so excited even more now.
Love this! The timing is perfect! We're educating children about reviving our lake in the neighborhood. How reintroducing native vegetation can rejuvenate water and purify the water body. Love the presentation. Thank you for your work Andrew!
I live in Kansas where there aren’t very many trees 😢. And some that are here don’t look very healthy. Loved you presentation. Things I have felt, but did not “know”.
I believe in Kansas you have a similar situation with your vast corn and other agricultural fields. This 'corn sweat' results in high humidity as the corn draws moisture from the ground and evaporates it into the air. This helps supply the moisture needed to form the sever t-storms and tornados through the 'alley'.
The magnitude of applicable & relevant knowledge each of your videos provide, along with the accessibility relative to comparable content, truly makes your channel an invaluable resource! As a microbiologist getting into permaculture to improve my home and my community, I can't thank you enough for the time you've put into researching and presenting on topics that help us understand how to repair our homelands!

Beautiful! My land is heavily forested - except for my front yard. (It came that way.) And my front yard is the only place on my property that has hard-packed, dry soil. My first job there is to plant trees.
Plant small fruit trees is my recommendation, then your house is protected from too much humidity and your yard is shaded and canopied… look at Geoff Lawton’s permaculture in small yards videos. They are really helpful.

This is clearly one of humanity's greatest resources, Andrew!❤️
Many years ago, I had a site meeting with city personnel for a construction job in a park. It was a hot day, and I parked my truck under the shade of a tree while waiting. The city arborist arrived and came unglued on me, explaining how damaging it is to trees due to the compacting of the soil. Lesson learned!!!
My decade of curiosity to get the answer for "Why Trees bring rainfall" ends today! Browsed multiple sites, but never could get an accurant answer like i got today. Thanks!❤❤

Thank you for taking the time to explain this. I didn't think about forests bringing water further away from the coast like that.
You bet! Glad it was helpful!
You're the man Andrew, thank you for your inspiring videos! Off to plant a hundred acorns in your honor
Awesome job in communicating that well and with the drawing. it is almost exactly what I have observed over decades of doing reforestation work. in Ecuador in the late 90's UBC Canada researchers where putting up water particle nets, but they plugged up with the living air plants. it was a time of pushing the carbon credit imported pine tree mono platations in the wrong echo system, as I witnessed indigenous communities destroy small native patches of high elevation brush forest. so a few of us pushed for a native tree nursery we built up, yet sadly the centre for studies and international cooperation told me they cut there environmental part of community development. I found however near the cloud nets that "Chilca Negra" grew like a wild native "weed" but its leaves formation act as partial channels to the hexagon stem that is slightly indented to drop the water to the base root of the plant. its a incredible natural technology of nature. sadly tho the climate change gatherings tend to divert attention from deforestation. where I sense the big issue is "investors" want to make quick return of profits from there investment by simple log and simple lumber and chip exports. Rather then community selectively log the trees that are beginning to rot or over crowd, and then processing locally the wood in to finished local products where you can not then make money from investing money, but you have to do the work to make a living and so many others can as well.
Thanks for this! 💚🌲🌳🌦💙 I love hearing & seeing this system explained with Andrew's fabulous illustrations. I'd love to see him tackle the increased transpiration cycle from keystone burrowers in arid temperate grassland climates that can't sustainably support forests. Bill Mollison listened to the Navajo legends of prairie dogs crying for rain & understood how their burrowing draws up moisture from the underground aquifers that move with the tides. I think it's fascinating how the prairie dogs perform some of the same ecosystems services as trees, in different ways, & from different kingdoms. Nature is amazing. I love zone 5. BTW, prairie dogs are down to 1% of their historic populations. Both deforestation & killing off native burrowers contribute to increased drought & desertification. Restoring both is important work.
Wow, fascinating. Where did you hear about the Bill Mollison part of that?
@@amillison , YT doesn't seem to let me reply to this thread. I have no idea why. I've tried twice. I suggested a search with Bill's name & prairie dogs.

Your are just too good Andrew ji. Love your sketching and way of explaining. Trees also break the impact of the rain drops and prevent soil erosion.
Great video. Both my parents were from farming communities. We always had gardens and now all my family enjoy gardening. I tried promoting gardening while working with summer camps, but my boss always came up with some excuse. With climate change, drought, flooding, famine...we have to start considering that some politicians and rich business men don't care whether people die or not and go from there...
Love this because the trees are our most loving partners as we are people of the trees. I hope this is spread far and wide! ❤

Your a great artist ! I love it . I saw this in my town . Shopping center I was at got no rain 🌧 as I drove one block to my home 🏡 that had lots of trees and it was Down pouring of rain . I do believe the trees bring rain 🌧!
And u also confirmed a lot of things I already knew. Thank you. Now I understand the whole system. At least as much as we know so far. It's so beautiful
You are a phenomenal teacher and love all of your videos. Thanks much. This brings to mind the microbiota/fungi below soil that contain the water and extend/enhance the soil stability and water carrying characteristics. Exchanging photons for electrons via the circuitry of water. Trees are just enormous phase altering portals for elements in the air, in the earth and through the water.
Fantastic content. More people like you please.
I'm grateful that you are continuing to do these videos! ❤
I love your art. Thank you for doing these videos
ikr, i cant believe he took the trouble.
Simply wonderful as always. Very very informative. Thank you .
This is a wonderful, *wonderful* inclusion of previously overlooked or undersupplied masses of information. I remember driving past a highway of lined trees, raining only where the trees were.
I live in my dear Colombia , and I have planted several mangos trees , I hope someday they give fruit , shadows and help to bring rain even though I won't be here anymore to enjoy all of them.
This channel is important for my mental health..😍😂
I need to send this to the local county planners and see if they'll sponsor new coastal planting
Give them a video or two on Geoff Lawton explaining various ways to make water catching part of the landscape… then the trees have a super chance to establish and recharge the ground water table.
I have used this video in my ecology class and it really helps break down this subject
Great! Not to mention the tree's exquisite beauty and unparalleled aesthetic appeal!
This was very enlightening and a great explanation!
Absolutely CORRECT! There is an old saying: "For every man should have a tree to write his name to!" So plant a "buddy" buddy. We have to find ways to stop destroying our own nature!
these videos are absolutely brilliant. clear, concise and informative without any arbitrary biases. thank you very much!
Glad you like them! Thanks for watching :-)
These are my favorite types of videos, and you are SOOOO good at these. Also, can we talk about the artistic quality of your sketches? Amazing! So glad to have you on team permaculture!
True … I love the art work also
Beautiful solution to creating a beautiful world!
I always learn something from your videos. Thank you so much for making and sharing them.
Thanks for watching!
I live on a natural short grass prairie where climate and moisture create conditions where trees really struggle without added irrigation. Do you think in the future you could put together a video of how important the prairie ecosystem is for sequestering carbon and holding soil moisture? I am all for planting trees, but context is important.
I did mention climax prairie ecosystems in my last video: How to Fix a Broken Ecosystem
@@amillison thanks. I'll find it.
Omg please that'd be great! I also live in a flat grassland part of the world and would love to see his explaination of how they work.
Swales, water catchments… working with the land through permaculture principles to plant the water back into the land… there are many videos a s sites which speak about how to do this… watch and read them all. I like Geoff Lawton’s videos a ton, because he explains as he demonstrates.
I refer back to this video regularily & share it more often. Thank you! With massive pressure on the coastal rainforests in B.C., you have made clear why it is crucial to protect existing forest ecosystems. The only issue I have with your video...at the end..."go plant a tree." Yes. In 10, 20 years, if it survives, it might make a difference. Please, please, please stress the importance of protecting old growth forest ecosystems ❤ first and where they are gone, plant a forest of trees and shrubs and wild things.
Nice explanation why trees and all natural resources are so important
Your knowledge is brought to life and so beautifully displayed in your artistry of the environment and how it works. It’s mesmerizing!
Over 80% of Amazon rainforest destruction is due to "livestock" industry. Dominion (2018)
Thank you for making clear the impact deforestation has in the climate crisis, and therefore, the importance of focusing efforts on forest preservation first, tree planting as secondary.
Thoroughly researched and brilliantly presented! Well done!
That was gorgeous. Thank you. I work in the Bush Regeneration sector in Australia, and you have just further enriched my understanding and passion.
Beautiful explanation…
💚 Beautiful and fascinating
The most beautiful educational video I've seen in a long time. Luv the illustrations to go along, perfectly.
Every time one of your videos comes across my feed it makes me wanna plant some trees
Thank you both for the video and for all the references in the description! They're so valuable!💙
Thank you so much for this video. You are a great teacher; easy to follow, engaging and thorough. I see that you're passion is in science; but I must acknowledge your art ability. You are a great artist. These videos work well for me because it is visual and audio. I have Incorporated your videos into our homeschool program. Keep up the good work brother.
I love you! In a completely plutonic way! Watching these videos and others like yours absolutely inspires me, so thank-you. You will have a real impact on what happens to our planet.
You've convinced me, I'll stop deforesting right away.
He gonna teach us how to draw like that next? 🤩
