Document Summary
Because of the flocking nature of the birds (always very dense population), they were very easy to exploit. As the human population has grown, and our use of resources has increased, we have destroyed the habitat of many species: a biodiversity crisis has developed. The world conservation union lists 16,913 species as threatened with extinction. For a lot of these groups, number of threatened in 2008, as % of described species is pretty high (ie. mammals, birds and amphibians = 10-30%). Numbers seem smaller for invertebrates and plants, but in terms of the number of threatened as a % of species evaluated these numbers are high. Bit of a bias because you end to evaluate species that you think are more threatened. Conservation biology (started in 1980s) the scientific study of phenomena that affect the maintenance, loss, and restoration of biodiversity.
