But when it comes to devastation (毁灭) of the natural world, we aren't so easily shocked.But we should be...or we'll be in a lot of trouble. Nature is shrinking by the day.Ancient forests are destroyed.Wetlands are becoming dry.Woodland is disappearing.And all in the name of progress.This is bad in itself, but it's devastating for biodiversity.

The loss of biodiversity could be devastating.“It is wrong to think that biodiversity can be reduced indefinitely without threatening humans，” said Harvard University biologist Edward O．Wilson, known as “the father of biodiversity”．He warned, “we are about to reach a critical point beyond which biodiversity loss will be unavoidable.” But what can we do?
