i. Conservation of Watershed
There are large varieties of plants and trees on the earth. These vegetations help to
conserve the sources of water. The areas which are covered by vegetations have less
chances to get dried up than the other regions. So, the sources of water are conserved in
such areas. It supports the life of different types of biodiversity. Without water resources,
biodiversity cannot survive and vice versa. Thus, the biodiversity plays an important role
in conserving water resources.

j. Tourism Development
Biodiversity provides beauty to nature. The tourists
are attracted towards those places which are rich in
biodiversity. They are interested in the observation,
study, conducting research and recreation. The
development of tourism in naturally rich places, helps
to develop eco-tourism. Eco-tourism helps to attract
domestic and foreign tourists which ultimately help
to develop economic condition of any place. Fig: 4

k. Environmental Balance
Biodiversity helps in maintaining the balance among the environmental aspects. For
example, plants and trees help to conserve the soil and water resources. After their death,
they mix in the soil and help to increase the fertility of soil. When any one of the components
are disturbed, the whole environment is affected. Our environment consists of biological,
social, economical and physical aspects. The biodiversity keeps various aspects interrelated.
Thus, the conservation of biodiversity helps to balance the environment.

l. Existence of Natural Ecosystem

Biodiversity is the main part of ecosystem. It has developed the natural processes like
water cycle, food cycle, carbon cycle, etc. It also helps in recycling carbon, oxygen and
other atmospheric gases. Its existence helps to maintain the fertility and productivity of
soil. Thus, biodiversity is important for the proper functioning of human life cycle and
natural ecosystem.

m. Study and Research Work
Biodiversity is an important field of study and research for several scientists, students,
researchers, etc. There is a wide scope to make research on it which will contribute to the
welfare of the whole living things including man. Similarly, by improving the breeds,
biodiversity of better quality can be produced. The economic and social development also
depends upon the study and research conducted on various aspects of biodiversity. The
study of biodiversity can contribute for the welfare of all living beings in the world.

Need of Conservation

Conservation refers to the preservation of all living beings, their required habitat and
their breed quality. Their conservation helps in increasing the number and quality of
