BIODIVERSITY :-
Biodiversity is the sum total of all
the varieties of species of
plants,animals and micro-
organisms living on the earth.It
also includes the habitat in which
they live.
Values Of Biodiversity
Direct values :-
Rosy periwinkle of Madagaskar for
leukamia.
Cinchona for Malaria.
Coca for Anaesthesia.
Domesticated animals provide us a number
of products like milk,wool,meat,skin,etc.
Indirect Values :-
Soil formation and its protection
from erosion.
Photosynthesis and carbon fixation.
Reducing the impact of flood and
drought.
Climate regulation at local as well as
global level.
Levels Of Biodiversity
Genetic Diversity
Species Diversity
Ecosystem Diversity
Hotspots In India
The two hotspots of biodiversity in
India are :-
The Western Ghats and
The Eastern Himalayas.
Threats To Biodiversity
The major threat to the
biodiversity is the human
consumption of resources.
Deforestation is the cause of
habitat destruction.
Forest fire.
Types Of Conservation Of
Biodiversity
In-Situ Conservation
Ex-Situ Conservation
In-Situ Conservation :-
• The in-situ conservation protects
the species in their natural habitat
or where they are.
• The in-situ conservation is more
cost effective.
Ex-Situ Conservation :-
The ex-situ conservation protects
and preserves the species in a place
that is away from their natural
habitat.
It includes ways like storage of
seeds in banks,setting up of
aquariums,botanical gardens,etc.
Mitigating People-Wildlife
Conflict :-
Fences and trenches is
recommeneded as it reduces the
interaction and thus the conflict also.
Some areas lack water bodies which
leads the animals from straying
outside the forest areas so water tanks
should be build in the forests.
A bufferzone should be created at
the forest periphery where people can
make limited use of forest products.
Hunting and poaching should be
strictly banned.
Eco-tourism and recreation forestry
should be tried as an income-earning
options.
Protecting Biodiversity
Wildlife Protection Act (1972) :-
Its objective is to preserve the biodiversity.
