Assess the effect
The effects of loss of biodiversity are :
1. There is a continuous loss in species. It has been declining rapidly. One example is the human habitation in the tropical Pacific Islands which led to the extinction of around 2000 species of native birds. In the last 20 years, more than 27 species have disappeared. Among various animal groups, amphibians are more vulnerable to extinction. The loss of various species on a large scale had taken place earlier on earth even before humans appeared. This has been confirmed by archaeologists, palaeontologist etc. by studying the fossil records. As is said history repeats itself, so is it happening. Just the difference is in today’s world the rate of extinction is way higher and faster than before.
2. Another major effect is the declining production of plants. This is the major cause driving animal extinction. The most shocking example is the reduced vegetation of tropical rain forests. Its coverage has reduced from 14% to 6%. They are being destroyed at a faster rate. Major forest areas of the world are being cleared just for making space for cultivation and human habitation.
Humans are never satisfied with what they have. They are always in search for more and more. This has led to over-exploitation of natural resources. Over exploitation hampers the normal functioning of a food chain, disturbing flora and fauna.
Due to loss of biodiversity species are also affected. In nature, there are many species which are interdependent on each other for various reasons. Extinction of one species may lead to the extinction of other species which are associated with it.
