Loss of Biodiversity

Nowadays it is common to read articles in newspapers and magazines regarding biodiversity issues. Human beings have been knowingly and unknowingly destroying biodiversity since their existence. Biodiversity is the measure of the variety of species of animals living in an area. Forests are usually areas with high biodiversity while deserts are the opposite. Human beings have always destroyed biodiversity either by deforestation, or by some other means. Biodiversity depletion is a natural phenomenon. But the present levels of biodiversity depletion are many times higher than the natural rate. Recently the levels of loss in biodiversity have started causing global concern. Some of the main causes for loss in biodiversity are alteration of habitats, increasing levels of pollution and human population growth.

One of the reasons for loss in biodiversity is alteration of habitats. A habitat is the natural environment in which a species of living organism lives. If the habitat of a species is changed, it will cause the species to die or migrate to other places where it can find its natural habitat. There are many ways in which the habitat of plants and animals can be altered. One of them is land use changes. Since the beginning of human life, human beings have been changing land use for farming. Large areas of forests have been cleared by humans to increase the area of farming to satisfy their growing needs. Many biodiversity-rich landscape characteristics have been lost due to intensive farming (Young, Richards, Fischer, Halada, Kull, Kuzniar, Tartes, Uzunov & Watt, 2007). For example, traditional farming was replaced by private farms in Europe after the First World War causing an immense change in land use patterns. Another major proble...

Loss of biodiversity is an environmental issue that is causing a lot of global concern. Some of the main causes for loss in biodiversity are alteration of habitats, increasing levels of pollution and human population growth. There are measures that are being taken worldwide to prevent loss of biodiversity. Many wildlife sanctuaries have been built worldwide to preserve the lives of various endangered species. However, it is important to remember that every individual has a role in the protection of wildlife and biodiversity. Every human being should play his part of the role by following simple rules such as stopping others from the hunting of endangered species, preventing deforestation, encouraging reforestation and creating awareness among fellow human beings.
