In this documentary David Attenborough takes you through his life story. The most important message he wants to give is that things are really going in the wrong direction with the earth and its biodiversity. He says that there is a mass extinction on the earth once every 100 million years. The most recent is the extinction of the dinosaurs.
Attenborough argues that if we continue to treat the Earth in this way, the next mass extinction could just happen in 2100. The deforestation of the earth plays a very large role in this. In the documentary this is made clear by showing how the earth was in terms of 'remaining wilderness' 80 years ago. In 1937 it was 66%, in 2020 this is only 35%. And this number is falling exponentially. The next 100 years will determine whether another mass extinction will take place. And it's not just the animals and plants that need to worry, humans too.
At the beginning of the documentary you see images of Attenborough in Chernobyl. Here he makes a comparison between the world in which we now live and Chernobyl. If we continue on this path, our planet, like Chernobyl, will also become an uninhabitable place.
However, there is hope that things will turn out fine. To restore stability to the planet, we need to restore its biodiversity. Attenborough believes this is the only way out of this crisis that we have created ourselves. So the world must be made wild again. And this is easier than you think. The trick is to raise the standard of living in the world, without increasing our impact on that world.
