to the breakdown of organic matter and release plant nutrients (Edwards and Bohlen‚ 1996). Earthworms are also considered as useful indicator of the health of soil ecosystem (Edwards and Bohlen‚ 1992) as to their role in soil fertility through fragmentation and mixed up the soil with mineral particle‚ enhancing microbial activity to breakdown plant organic matter. The contribution of earthworms in soil turnover‚ structure formation and serve as a fertility enhancer in different way. Earthworms are

can infringe on the natural habitats of countless species. Kolbert writes about the Sumatran Rhino whose habitat originally was around the foothills of the Himalayas but due to a high rate of deforestation their habitat became fragmented and was reduced to a few hundred. This grave fragmentation of the species made it incredibly difficult to breed and recover their numbers which led to rhinoceros captive breeding programs. The deforestation that caused such drastic habitat loss was specifically for
Premium Human Extinction Natural environment
HUMANS help make big fierce animals rare. We hunt them for many reasons: 1. they’re killing our livestock 2. they eat our pets because we’ve moved into their natural habitat 3. pride and the need to assert one’s "machismo" over the forces of nature. This one is incredibly disgusting‚ especially in so called "canned hunts." These hunts trap animals and put them in an enclosure‚ so that people can come and "hunt" them with a guarantee of a kill. 4. we want to sell parts of them: tusks/horns‚ heads

India all the way north to Uzbekistan -- houses a variety of endangered species. Dwindling populations of both larger animals like the snow leopard and smaller animals like the Bunn’s short-tailed bandicoot rat are primarily due to habitat fragmentation and destruction. Habitat conservation and awareness are imperative in preventing these endangered species from becoming extinct. Large Mammals One of the best-known endangered large mammals in the Middle East is the snow leopard (Panthera uncia). These

Environmental issues are harmful effects of human activitity on the biophysical environment. Environmentalism‚ a socialand environmental movement that started in the 1960s‚ addresses environmental issues through advocacy‚ education and activism. The carbon dioxide equivalent of greenhouse gases (GHG) in the atmosphere has already exceeded 400 parts per million (NOAA) (with total "long-term" GHG exceeding 455 parts per million). (Intergovernmental Panel on Climate Change Report) This level is considered

The legislation forbidding commerce includes wildlife threatened with extinction anywhere in the world. Critical habitats must be targeted for preservation and management to aid the recovery of the species. 7. Hgljjj; 8. Biodiversity is a result of speciation and extinction

marine ecosystems are threatened to the extent that their structure and function is being jeopardised. The most serious threats to marine biodiversity are: • Over exploitation - recreational and commercial • Pollution • Habitat destruction and fragmentation • Non-native species invasions • Global climate change Threats to marine biodiversity have widespread social‚ economic‚ and biological consequences‚ the combination of which could threaten our own existence‚ including: • Economic
