Biodiversity - the Earth's natural balance of plants and animals - helps mitigate the effects of climate change. When it is destroyed, both nature and people suffer.
Scientist call it the Holocene extinction event - 70 percent of 400 biologists questioned by the American Museum of Natural History believe that we are witnessing the early stages of a human-caused mass extinction.
This loss, however, could have dire consequences. The Earth's abundance of species is one of the best protection mechanisms against natural disasters - and possible impacts of climate change.
