Loss Of Biodiversity Essay

1094 words - 4 pages

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 problem that contributes to habitat alteration is introduction of exotic species. Exotic species are those that are introduced into a habitat that they do not belong to. Species that are genetically modified by scientists and researchers fall under this category. Even the presence of exotic species might be highly destructive to existing biodiversity (Prévot-julliard, Clavel, Teillac-deschamps & Julliard, 2011). This is because exotic species tend to establish themselves when they are newly introduced in a habitat. They scatter through the area and create a negative effect on the existing biodiversity. Sometimes, the alteration of habitats can reach such an extent that there is extensive loss of land use characteristics. This leads to a complete loss of the entire habitat. In extreme cases this may lead to extinction of species in that area.
Increasing amounts of pollution is another reason for loss in biodiversity. Pollution is the introduction of such foreign substances that can cause damage to the natural environment. One of the main effects of pollution is climate change. Climate change in turn causes a huge change in biodiversity patterns. Moreover, the consequences of climate change are almost irreparable (Kappelle,...

Dangers to biodiversity include intentional murder of species by hunting, or by contaminating their environment with various toxins, and by destroying their habitat. The loss of biodiversity through any means must, in the end, be changed by changing human behavior. Otherwise, we humans will annihilate the same environment that cares and provides for us. It

The subtle loss of biodiversity fails to indicate the significance that fewer species in the ecosystem increases the fragility of life for all species. Despite the negative effects of deforestation and the consequential decline of biodiversity, trees are cut down for an economic and consumer benefit. Members of

This lack of organisms due to food will result in loss of biodiversity and thus loss of ecosystem function. Another component of proper ecosystem function is nutrient cycling. Nutrient cycling is important to an aquatic ecosystem because certain recourses in an ecosystem

The largest contributions to biodiversity loss are all rooted in human overpopulation, and brought about
