Extinction is the ceasing of a species to exist on this Earth. A species officially becomes extinct when all of the species no longer exists. A species is to become certainly extinct when there is an extremely small number of it and it is unable to reproduce to create more of itself. Therefore‚ we say a species is in for certain extinction if it cannot reproduce itself. Extinctions occur at a great pace and species that we did not even know existed become extinct all the time. Scientists say that

Land pollution is the deterioration (destruction) of the earth’s land surfaces‚ often directly or indirectly as a result of man’s activities and their misuse of land resources. It occurs when waste is not disposed off properly‚ or can occur when humans throw chemicals unto the soil in the form of pesticides‚ insecticides and fertilizers during agricultural practices. Exploitation of minerals (mining activities) has also contributed to the destruction of the earth’s surface. Human actions have

EVS REPORT – BATCH 2 – THE MAP OF ENDANGERED No one will ever again see a paradise parrot flash its rainbow colors across the sky or see the Tasmanian tiger slink through the wet Tasmanian forest. They are gone forever – they are now extinct. It is very sad‚ but it is too late. Extinction is forever. Plants and animals have become extinct before. Dinosaurs are an example. However the process is slow‚ taking thousands of years and longer‚ allowing sufficient time for other life forms to adjust to

coastal regions are volatile components‚ oil drilling‚ ocean acidification‚ habitat and biodiversity destruction‚ and extreme weather conditions. Surprisingly‚ the routes by which theses stressors are released are via the atmosphere‚ lithosphere‚ and hydrosphere. In the article A Procedure for Evaluating Environmental Impact it demonstrates the need to properly assess plans into human infrastructures in various habitats; especially that of coastal biomes. This article encourages to consider the

human- induced stress. Ecosystems rich in biodiversity generally have greater resilience than those with little diversity. They are able to recover more readily from naturally induced stress (including drought and fire) and human- induced habitat destruction. 2. Under what conditions does long-term degradation occur? Long-term degeneration occurs when the magnitude and duration of the stress exceed the ability of the component to repair itself. 3.Explain the

By destroying the marine habitats within our seas and oceans‚ humans are threatening their own livelihood by not only destroying a food supply but also other benefits that marine life offers. Pollutants such as‚ everyday trash‚ chemicals‚ and farm fertilizers are not only killing off marine life‚ but also destroying natural habitats within those waters.

Seagrass Habitat Executive Summary The purpose of the report is to propose a research on the impact of coastal development to seagrass habitat. This project shows the processes and final results from the survey and research on library and internet that we have conducted. From the survey‚ we found that the impact of coastal development to seagrass habitat have become a serious problem that will face by human being. Meanwhile‚ the major problem they might face if loss of seagrass habitat is lack
