2. BIODIVERSITY
Biodiversity is the variety and variability of life on Earth.
Biodiversity is typically a measure of variation at the genetic,
species, and ecosystem level. ... These tropical forest
ecosystems cover less than 10 percent of earth's surface, and
contain about 90 percent of the world's species.
3. CONCEPT OF BIODIVERSITY
Biodiversity is the variety of different
forms of life on earth, including the
different plants, animals, micro-organisms,
the genes they contain and the ecosystem
they form. It refers to genetic variation,
ecosystem variation, species variation
(number of species) within an area, biome
or planet.
4. SIGNIFICENCE OF BIODIVERSITY
Ø Most of the drugs which are now in commercial trade are derived directly or indirectly from biological resource
Ø About 50% of drugs used in US are derived from biodiversity
Ø According to WHO, 80% of world population depends on medicines from nature (biodiversity is the integral part of
nature)
Ø Many industrial materials are deriving from biological sources. These include building materials, fibbers, dyes, rubber
and oil
Ø Biodiversity provide security of resources such as water, timber, paper, fibre and food
Ø Biodiversity support leisure activities such bird watching and trucking
Ø Biodiversity also inspires musicians, painters and writers
Ø Gardening, fishing & specimen collecting are depends on biodiversity
5. WORLD BIODIVERSITY
Man has made remarkable advancements in many fields of science but when it comes to
recording and scientifically describing different kinds of plants, animals and
microorganisms, there remains much more to be explored and recorded than they are
known. The known and described number of species of all organisms on the earth is
between 1.7 and 1.8 million, which is fewer than 15% of the actual number. The
predicted number of total species varies from 5 to 50 million and averages at 14 million.
Out of the total known species, about 60 % are insects, about 16 % are higher plants and
only about 0.3 % are mammals. There are many more species that have not yet been
6. VALUES OF BIODIVERSITY
Direct values. These are those ways by which we can directly use biodiversity for our benefit. ...
Indirect values or Non-Consumptive value. ...
Social values. ...
Ethical and Moral value. ...
Economical value. ...
Aesthetic value. ...
Ecological value. ...
7. WHY BIODIVERSITY IMPORTANT
Biodiversity boosts ecosystem productivity
where each species, no matter how small, all
have an important role to play. ... A larger
number of plant species means a greater
variety of crops. Greater species diversity
ensures natural sustainability for all life
forms.
8. GENITIC DI VERSITY
Genetic diversity is the total number of
genetic characteristics in the genetic
makeup of a species. It is distinguished from
genetic variability, which describes the
tendency of genetic characteristics to vary.
Genetic diversity serves as a way for
populations to adapt to changing
environments.
9. What is tha good of conversation
Objectives and advantages of biodiversity
conservation
The genetic diversity of plants and animals is
preserved. It ensures the sustainable
utilisation of life support systems on earth. It
provides a vast knowledge of potential use
to the scientific community.
10. CONCLUSION OF
BIODIVERSITY
The problems and benefits of biodiversity are many. They focus on
the need for sustainable development and adequate use of coastal
resources. Loss of biodiversity and biodiversity conservation are
concepts that provide the basis for biodiversity management
