So this last question is supposed to be a short essay about the importance of preserving biodiversity.
00:06
Now, i'm not going to write the essay, but i will provide three key points that one should think about.
00:11
So the first one is ecosystem services.
00:14
Ecosystem services are things that an ecosystem does that help benefit humanity.
00:22
Sometimes you can attach a dollar value to it, like hunting, fishing, flood protection.
00:28
Other times it's harder to attach an economic value, such as the enjoyment of walking through the park or the beauty it provides.
00:38
Now, biodiversity is important for these things because one, no one wants to go through a park and just see a flat expanse of grass that's boring.
00:48
We'd much rather see butterflies and birds and flowers and trees.
00:54
And then also think about things like for flood protection.
00:59
The increased number of plants you have in an area is going to help mitigate the effects of a flood.
01:06
So if you have a variety of different trees along the river bank, those trees will all help lessen the impact of the flood and how far the flood goes out...
