6. INTRODUCTION
The term BIODIVERSITY
was first coined by
WALTER.G.ROSEN in 1986.
Biodiversity is abbreviation
Of Biological diversity.
The biosphere comprises
complex collection of
innumerable organisms known
as the biodiversity which constitute the vital
life support for survival of human race .
Biodiversity represents various life forms such as
plants ,fishes ,mammals etc. at various biological
levels.

7. THERE ARE THREE TYPES OF
BIODIVERSITY
 Diversity of species.
 Diversity of ecosystem.
 Diversity of genes.

8. IMPORTANCE OF BIODIVERSITY
 Balance of nature.
 Biological productivity.
 Regulation of climate.
 Maintenance of soil
fertility.
 Cycling of nutrients.

9. BIODIVERSITY HOTSPOTS
A region with high
biodiversity with most of
species being endemic .
 India have two
biodiversity hotspots –
East Himalayan region
and western ghat.

10. THREATS TO BIODIVERSITY
 NATURAL CAUSES
• Narrow geographical area
• Natural disasters.
 ANTHROPOGENIC CAUSES
• Habitat modification.
• High population.
• High breeding rate.

11. • Pollution.
• Global warming .
• Change of climate

12. RECENT ISSUES ON
BIODIVERSITY
 We lost 75% of crop plants
in past century.
 Scientist estimated 3 species
per hour are going extinct and
20,000 extinctions occur each
year.
 One third of the world coral reef system have
been destroyed.
 About 24% of mammals and 12% of bird
species are currently considered to be globally
threatened.

13. CONSERVATION OF
BIODIVERSITY
 Imparting environmental
education.
 Population control.
 Reviewing the agriculture
practice.
 Controlling urbanization.
 Conservation through
biotechnology.
 Enacting, strengthening and enforcing environmental
legislation.

15. CONCLUSION
Biodiversity is our life.
If the biodiversity is lost at
this rate then the survival of
human in future will be
threatened. So it is our moral
duty to protect biodiversity
and environment.

16. We celebrate international day on
biological diversity on MAY 22 .
