2. the variety of plant and animal life in the
world or in a particular habitat, a high
level of which is usually considered to
be important and desirable.

3. There are three types of biodiversity
 Diversity of Species
 Diversity of Ecosystem
 Diversity of Genes

4. Diversity of Species
 Species is a basic unit of classification and is
defined as a group of similar organisms that
mate and produce offspring’s with one another
and thus, share a common lineage. The numbers
of species of plants and animals that are present
in a region constitutes its species diversity.

5. Genetic Diversity
Each member of any animal or plant species differs
widely from other individuals in its genetic makeup
because of the large number of combinations possible in
the genes that give every individual specific
characteristic. Thus, for example, each human being is
very different from all others.

6. Diversity of Ecosystem
 Ecosystem diversity deals with the
variations in ecosystems within a
geographical location and its overall
impact on human existence and the
environment.

7. BENEFITS OF BIODIVERSITY
Consumptive value:
 Food/Drink
 Fuel
 Medicine
 Batter crop varieties
 Industrial Material
Non-Consumptive Value:
 Recreation
 Education and Research
 Traditional value

8. THREATS TO BIODIVERSITY
Natural causes:
 Narrow geographical area
 Low population
 Low breeding rate
 Natural disasters
Anthropogenic causes:
 Habitat modification
 Overexploitation of selected
species
 Innovation by exotic species

9.  Pollution
 Hunting
 Global warming and climate
change
 Agriculture
 Domino effect

10. • India is the seventh largest country in the
world.
• Second largest nation in Asia.
• land frontier- 15,200 kms
• Coastline of 7,516 km.
• One of the top twelve megadiversity
countries

11.  No of plant species- 49,219 (12.5% of the
world)
 No of animal species- 81,251 (6.6% of
world fauna.)

12. No. Category No of species %
1 Bacteria 850 0 67
2 Algae 2500 2. 00
3 Fungi 23000 18.23
4 Lichens 1600 1.30
5 Bryophytes 2700 2.14
6 Pteridophytes 1022 0.80

8 Angiosperms 17000 13.50
9 Protozoans 2577 2.04
10 Molluscans 5042 4.00

13.  Species endemism among plants- 33%.
 Endemism among animals
1. mammals –low, only 44 species.
2. Birds-low, only 55.
3. Reptile-high,187.
4. Amphibia- high,110
 National parks-89 &
 Wild life Sancturies-497}1.56 lkh sq.km-
 Tiger reserves-27- 37761 sq.km

14.  Area- 38,863 sq. km, (1.2 % of the total
geographical area of India.)
 Coast line- 560 km .
 Altitudes up to 2694 m above msl.
 mountainous upland-75-2,694 m above msl- 48%
( Forest
biodiversity)

15. • Midlands-8-75 m above msl- 42%
(Agrobiodiversity)
• Coastal belt-0 to 7 m above msl-10%
(Aquatic biodiversity)
• Among the States located within the
Western Ghats region, Kerala is the richest
in biodiversity.

16. • Biological Diversity Act, 2002(Central Act
No. 18 of 2003)
• Biological diversity rules, 2004
• Chapter VI section 22 to 25 of the Act calls
for the establishment of state biodiversity
boards by the state governments
• This act and rules provide guidance to union
and state governments for:

17. Some Questions

18. Why should we care about
biodiversity?
 Human activity is causing the diversity of life on earth to be
lost at an accelerated rate (1000 times its usual rate!)
 Biodiversity is essential to sustaining the living networks and
systems that provide us with, health, wealth, food and fuel.
 Without biodiversity life as we know it today would not exist.
Humans are part of natures Biodiversity, we have the
power to protect or destroy it.

19. What can we do?
 Spend time outdoors
 Plant trees
 Support companies that work in ways to
reduce environmental damage.
 LEARN MORE about Biodiversity.
What else can YOU think of?

20. Reflection
Lets reflect on what Biodiversity means
to us and our community and how it
influences the way we live. Why should
we care about biodiversity?
