Biodiversity – UNEP
(8 min) Even if our knowledge about earth is incomplete and our concepts are far from being coherent – one disturbing trend is becoming increasingly obvious: biodiversity, the richness of animal and plants, is currently being lost at unprecedented rates. Direct human impacts are the main cause. More species have become extinct in the last 150 years than in all recorded history. Today almost 30% of all species are threatened with extinction and probably less than 1% of all human beings are aware of that. The world as we know it might never have existed.
