Abstract- There is diversity of life on Earth. The diversity of living beings is the basis that every civilization has used for its growth and development. Who used this gift of nature wisely and sustainably. Those civilizations survived while those that overused or misused them were destroyed. Science has been attempting to classify the diversity of nature for more than a century. Due to this he came to know about various types of communities of plants and animals. This information has helped in using the Earth’s living resources for the benefit of mankind and has been an integral part of the process of “evolution”. This also includes better health care, better crops and the use of these life forms for industrial development, due to which the standard of living has increased in developed countries. But due to this, modern consumerist society has also arisen which is adversely affecting the diversity of the biological resources on which it is based. The diversity of life on Earth is so great that if we If we use it, we will continue to develop new products from biodiversity for many generations. Biodiversity plays an extremely important and major ecological role in the biosphere. Biodiversity brings stability to the environment. Therefore, bio-diversity is very important to keep the ecosystem favorable for living beings so that there can be sustainable development of all living beings and we can also continue our existence in the future. Biodiversity and conservation have been explained in detail in the presented paper.
