Save tree algorithms #teamtrees


If you watch my programming videos,
you likely know this type of trees. They have a root, leaves, subtrees and so
on. But today we’re talking about this type of
tree. Maybe not particularly this one that is ugly
and hand-drawn. But real trees are important
and this is what I’m talking about today. You might have already heard about MrBeast’s
challenge to plant 20,000,000 trees. A lot of big Youtubers are involved in this,
I want to join them too. The goal is to plant 20,000,000 trees thanks
to your donations and my small donation too. And in the next two years, we will have 20,000,000
new trees, that is quite a big number. The charity is called TeamTrees,
the website is teamtrees.org. You can go there right now and make a donation. 1 dollar=1 tree
And you’re not only paying for planting a tree. It will also be maintained,
first the location where the tree is planted is chosen smartly,
so your 1 dollar is not wasted. Also this charity has high rating
what means they don’t waste money, they are very efficient
and it’s a very good cause. I also made my own donation. Actually, around two months ago
I decided that I want to somehow help the environment even though e.g. I take a lot of Uber trips… (And the thing is that cars cause big pollution
and it’s much better to use public transport.) so I went to my account two hours ago,
I found 80 rides in my history… It was my idea two months ago to donate 1
dollar to some kind of tree charity for every ride that I have
just to cancel bad effect plus I donated some more and here’s a proof: I’m a good human and I’m now officially
a member of #TeamTrees and you can be a member too,
you can help save the Earth, the environment. Go to teamtrees.org and donate 1 dollar, 5
dollars. If you can’t afford that, just share in your
social media, share the idea with your friends
so that they could donate. This is also helpful. You might wonder why I’m so enthusiastic about
this environment thing. One reason is that I like bears. You might often see them in my problems,
for example in Codeforces. When I come up with story for a problem,
the hero is often bear Limak. Sometimes, he’s a little polar bear, sometimes
a brown bear, and so on. You can see here my three figurines. Black, polar and brown. And yeah, I like bears and I think they should
have a place to live. Some of them live in a forest, some of them need ice and snow to live,
but also because of global warming they don’t have that ice, they won’t have that ice soon. Figurines aren’t the only thing I own related
to bears, you can check out my t-shirt. It says “Ladies and gentleman, this is bear”
or teddy bear. And I very much like it. You can try to find some of my old videos
or streams where I wear exactly this t-shirt. And what else? teamtrees.org started as a challenge for big
Youtubers so let me challenge my Youtuber friends that
are Gaurav and Clement. You should too make some videos related to
trees and ask your audience to donate to teamtrees.org and let’s together plant 20,000,000 trees. Ok, thank you all for watching and I hope
you don’t mind this different format of a video. But I think the cause is great,
so donate, share with friends and maybe also change your life just a little bit, to affect the environment in a smaller way. Start by recycling for example. See you in the next video about trees, I guess. Save bears!
