6 Problems Caused by Shrinking Biodiversity
Estimates of species loss are, without a doubt, staggering. In 2007, Sigmar Gabriel, the then-Federal Minister for the Environment, Nature Conservation and Nuclear Safety of Germany, cited estimates that up to 30% of all species will be extinct by 2050 if climate change continues to progress as it has been. Others have estimated that as many as 140,000 species are lost each year.1 The alarming trends have led some to declare the current period the "Sixth Mass Extinction."2
But, extinctions—even mass extinction events—are not new. Though the current trend is caused, undeniably, by human action—through poaching, habitat destruction, pollution, and anthropogenic climate change, among others—mass reductions in biodiversity can and have occurred without human interference.3
The question then, is what does humanity lose when global biodiversity is significantly reduced?
Simply: a lot. Here are six significant human problems caused by reduced biodiversity.
