The number of species of living organisms and plants available in any natural region is called bio – diversity. The word bio – diversity was first used by American entomologist E. A. Wilson in 1986, which was later adopted by other scientists and environmentalists in the form of a concept.
There are countless organisms present on the earth, in which genetic, ethnic and ecological diversity is found. Biological diversity is defined differently by different people. Different types of variations found in living beings are the result of biological evolution in millions of years. All the biospheres are evolved and controlled through these variations. This variation in animal and plant species scientific is called bio – diversity in language. Some scholars have written that the basis of human life on the earthly, homestead ship is the bio – diversity.
Concept / Theory of Bio – diversity: The body of each organism is made of its genes, and the functioning of its body is also controlled by these genes. Gene is the fundamental basis of the bio – diversity of the biosphere. Concept / theory of bio – diversity has developed in the past years due to environmental degradation. Biological diversity and prosperity is one of the most important qualities of nature, which is the result of the process of development on the earth and which requires sustained protection.
Due to the unimaginable destruction of natural habitats, there has been a crisis of declining bio – diversity over the past years. For example, the hunting of Krishna (black) deer in our province of Rajasthan, hunting of around half a dozen elephants in the world famous Jim Corbett National Park, the death of 13 tigers in due to a disease called Triapinasymiosis, in Nandan Kanan reserve, etc. Such unbearable events strongly support this reality that even in our country, the bio – diversity sphere has not remained untouched by the imminent crises.
The survival of bio – diversity is very important for the sustenance of human life. The origin of pollution is the product of human activities. The graph of bio – diversity is definitely decreasing due to pollution which continues to be progressively increasing. So far, humans have ended the entire existence of about one million animal species and about 76% of wild animals, for their own benefit.
The decrease in bio – diversity is an important problem in the current world. Its deficiency affects the evolutionary capacity of living organisms and they find themselves helpless to adapt to environmental changes.
In the concept of bio – diversity, the species have a decisive position. In nature, it is said to be a kind of productive life and the same type of living creature as the productive descendant of a lineage growth. In nature, species join and give rise to new ones through evolution. Thus, bio – diversity is a very important condition for sustainability of life and longevity and sustenance of the environment.
