Saving this habitat also benefits other species, Flagship species are especially interesting or attractive organisms to which people react emotionally. For example, after the Ice Ages, when the glaciers melted and the earth became warmer, many species died because they could not live in a warmer climate. Almost all potatoes cultivated, sold, and consumed, for instance, are from a single species, the Russet Burbank. It is therefore considered to be facing a high risk of extinction in the wild. The genetic variation of wild potatoes allows them to adapt to climate change and disease. (a) A threatened species means that the population is likely to become endangered whereas an endangered species has population number so low that it is likely to become.
