ENDANGERED SPECIES
Endangered species are living things whose population is so reduced that they are threatened with extinction. Thousands of species are included in this category. The International Union for the Conservation of nature and Natural Resources publishes a list of threatened mammals, birds, reptiles, amphibians, and (many people donÕt consider them) plants.Millions of years before humans, extinction of living things was linked to geological and climate, the effects of which were translated into major alternation of the environment. Environmental change is still the primary cause of the extinction of animals, but now the changes are greatly accelerated by humans activity. Clearing land for farms and towns, lumbering, mining, building dams, and draining wetlands all alter the environments so extensively that ecosystems may be completely destroyed. With a burgeoning human population requiring food, shelter, and clothing and constantly demanding more energy-using devices, the te
These include the big cats, alligators, kimonos, quetzel birds, eastern gray kangaroos, egrets, and bids of paradise. Thus, the wearer of a ranch-raised Russian sable coat may have indirectly contributed to the ultimate disappearance of the great whales. Whaling is often justified as supplying a source of protein for protein-poor populations. Industrial waste dumped in the Mediterranean have so depleted the oxygen supply that some species of bacteria that decompose sewage have been wiped out and the nutrient cycles disturbed. Many people and groups have taken measure to stop the killing of endangered species. ÒEndagered Species,Ó Grolier Encyclopedia, VII (1993),1-6. In conclusion I just want every one to know that endagered species can be as big as a blue whale or as small as a tiny little ant. Ó National Geographic,CLXXV (June, 1993), 662-698. Species of salamanders in New England are dying out because the ponds in which they breed and the moist soil in which they must live are watered by acid rain (water that combines with pollutants in the air to form acid, sulfuric acid, and other corrosive compounds. Actually, whales supply only 1% of the protein needs of any countries, such as Japan, that is actively engaged in whaling. They also become more accessible to hunters, who kill monkeys for food and trap many primates for sale as pets, research animals, and zoo specimens.
