Question

What were the reasons for the disappearance of flora and fauna​

Answer 1

17,315 mammals, birds, plants, insects, coral, fungi and other species are currently threatened with extinction according to the IUCN. The number of so-called ‘hot spots' or particularly endangered regions are spread across the globe from California to the Caribbean, South America, the Mediterranean and Africa's Congo basin, from the Himalayas to Japan, where the famed snow monkeys are threatened, and into the Pacific region.

The rate of species extinction since 1600 was, until recently, 50-100 times the historical rate tracked by scientifically analyzed fossil records. Alarmingly this extinction rate is now expected to accelerate to between 1,000-10,000 times the natural rate by 2020.

For the first time in history according to Ahmed Djoghlaf, executive secretary of the CBD "experts are talking about a human-generated mass disappearance of species."
