So we're looking at biological diversity and there are three levels of it.
00:04
Level one is ecosystem.
00:09
So we have ecosystem diversity, which is the largest scale.
00:16
Entire ecosystems are being destroyed, particularly forests, grassland, etc.
00:25
And also coral reefs.
00:27
So these are just some examples of places where human activities are threatening.
00:33
Ecosystem diversity, coral reefs by climate change, forests by deforestation, there's also the use of pollutants, which affects wetlands and forests, and also aquatic rivers.
00:49
So there's many ways that we affect the ecosystem.
00:53
Second, we have species diversity, so a little smaller scale...
