An absolute description of the threat hanging over the world's mammals, reptiles, amphibians (哺乳、爬行、两栖动物) and other life forms has been published by the wellknown scientific journal, Nature. A special analysis carried out by the journal indicates that an astonishing 41% of all amphibians on the planet now face extinction while 26% of mammal species and 13% of birds are similarly threatened.
Many species are already critically endangered and close to extinction, including the Sumatran elephant, Amur leopard and mountain gorilla. But also in danger of vanishing from the wild, it now appears, are animals that are currently rated as merely being endangered.
In each case, the finger of blame points directly at human activities. The continuing spread of agriculture is destroying millions of hectares of wild habitats(栖息地) every year, leaving animals without homes, while the introduction of newlycome species, often helped by humans, is also damaging native populations. At the same time, pollution and overfishing are destroying ocean ecosystems.
