Human activity on the planet has caused an unprecedented decline in biodiversity in recent years. Wildlife species are disappearing tens to hundreds of times faster today than they were in the past 10 million years.

Between 2010 and 2015 alone, more than 30 million hectares of forest disappeared. The conservation of biodiversity depends heavily on the protection of the world's forests and how to deal with them, says Murad Babaa, author of "A World Without Forests" "There is no doubt that the environmental manipulation of the planet can turn something like the situation we are currently experiencing into something like a sixth wave of extinction," he says.
