Brazilian Amazon rainforest (International Business Times, 2018) The loss of biodiversity can lead to a breakdown in the functioning of the ecosystem where decline has happened. An area’s biodiversity may increase and decrease following natural cycles. In contrast, human-driven biodiversity loss tend to be more severe and longer-lasting: ecosystems have adapted to the challenges of natural disturbances. However, humans, our crops, and our food livestock take up half of the world’s habitable land, and overexploits 90% of the fishing stocks. This massive conversion of forests, wetlands, grasslands, other terrestrial ecosystems, and the ocean, has produced a 60% decline in the number of vertebrates worldwide since 1970. The Rockefeller Foundation/Lancet Commission reports that human health depends on natural systems functioning properly. Biodiversit...
