To what extent are surrounded species able to stand the anthropogenic activities?

julsineya [31]

Answer:

At the current rate, surrounded animal species might not be able to stand anthropogenic activities in the nearest future.

Explanation:

Anthropogenic activities are those human activities that causes change in the biophysical environment, ecosystems, biodiversity, and natural resources. It also includes global warming, mass extinction of animals and loss of bio-diversity and other global disasters brought about by human activities.

The main driving force of anthropogenic activities is the pressure brought about by the ever growing human population. The earth is overpopulated by humans, and this pushes man to maximize his environment, even to the detriment of this environment. Animal species are hunted to extinction due to increasing demand for their meat, or ornaments gotten from these animals, or some of their body parts, perceived to hold medicinal power, industrial activities poison the environment and natural resources all around, and some ecology has been destroyed and native species population decimated, just because man felt he had to control his environment, sometimes by introducing foreign species he feels he needs.

If nothing is done to halt the current rate of anthropogenic activities, by controlling human population growth, man might end up occupying the planet all alone by himself with surrounding species utterly destroyed.
