Because these ecosystems are so vast‚ and have such impacts‚ it is important to understand how they function. To determine how an ecosystem is functioning‚ the stability of the ecosystem is taken into consideration. Stability is defined as the tendency of a system

us. Forests act as a habitat and shelters to millions of species. However‚ these trees are being depleted at a very fast rate. According to some estimates‚ more than 50 percent of the tree cover has disappeared due to human activity. Deforestation is the destruction of forests and woodlands. The term does not include the removal of industrial forests such as plantations of gums or pines. Deforestation has led to the reduction of forests to four-fifths of their pre-agricultural area. Forests now cover

Over the decades‚ Invasive species have shown a significant negative impact upon the fabric of the ecosystem. Whether they are endangered or not‚ in-habitat species are making their presence known throughout the ecosystem‚ and such‚ throughout the United States. In fact‚ Invasive species have posed as a problem within society as around the early colonies of the 1800’s. The uncommon native-species are able to enter through different routes. Some are transported intentionally and others are able

The creeping water primroses can cause a lot of harm to the ecosystem such as depletion of oxygen levels in water‚ attract mosquitoes that carrying virus‚ and completes with native species for space and resources.

Environmental issues are harmful effects of human activitity on the biophysical environment. Environmentalism‚ a social andenvironmental 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
