Humans have been associating with ecosystems and changing them for as long as the start of human life. An ecosystem is a community of species and their non-living environment working in cohesion. Ecosystems at risk‚ such as The Amazon rainforest and the GBR are those which are heavily affected by change and if altered they require a long time to return to their former state. Human activities such as fishing‚ tourism and deforestation have had huge impacts on the balance of these ecosystems. The

The natural world is seemingly perfect‚ a multitude of entities exist that allow complex life forms to survive‚ while permitting various species to live alongside each other. The environment allows for biodiversity to take place; this factor allows for many forms of life to exist in harmony‚ also allowing for genetic variations of various species to survive. Since humans have been introduced into the environment‚ we have desired to maintain control of our surroundings by forcing nature to work for

Biology Ecology Diversity Index Lab Introduction The measure of the biodiversity of organisms in a given area is known as the diversity index. The diversity index values will vary between 0‚ which would indicate no diversity‚ and 1‚ which is very diverse. Any values above 0.5 usually indicate a relatively diverse population. For example‚ a healthy forest or woodland should have a diversity index of 0.7. An area that is not very diverse‚ like a cornfield‚ might have a diversity index of

The North Cascade Mountains are a vital part of Washington’s environmental function and beauty. They are being threatened by deforestation and mining. The clear-cutting of the forest would result in loss of wildlife and biodiversity due to loss of habitat and environmental “disruption”. Mining is potentially dangerous to water supplies which in turn affect the animals that live in and drink from them. Washingtonians are attempting to preserve two hundred thousand acres of land surrounding the North
