4. Introduction
 The science of biodiversity originates largely from
ecology (the study of the relationship between
organisms and their environment) and evolution (the
study of the origin of diversity).
 From these two fields come its two main goals: to
understand the way the natural systems work and
are structured, and to understand how it got that
way.
 Biodiversity also provides us with a community of
life, with which we share planet Earth, and the
opportunity to practice thoughtful stewardship

5. What is biodiversity?
Biodiversity is the variety of all life
forms:the different plants,animals and
micro-organisms ,their genes and the
ecosystems of which they are a part.

7. Types of biodiversity
There are three kinds of biodiversity.
One type is
genetic diversity
which is
the diversity of genes in a species. Species
need certain genes to survive. If the diversity
is lacking, the species may die, and its numbers
will diminish.

8. Types of biodiversity
Species diversity (another kind of
biodiversity) is the variety of living things in
areas such as rainforests, reefs, deserts,
tundra, etc.
The last type of biodiversity is ecological
diversity. It’s the complexity and richness
of an entire ecosystem.

10. Why is biodiversity important?
Biodiversity increases ecosystem
productivity; all of the species in that
ecosystem, no matter their size, have a
big role. A diverse ecosystem can
prevent a nd recover from lots of
disasters. Humans depend on plants and
animals. For example, one quarter of all
prescription medicines in the U.S. have
ingredients from plants. If a diverse
ecosystem is more productive, it's easier
to get these plants.

11. Why is biodiversity important?
Humans also directly benefit from a diverse
ecosystem: plants, clean water and air, provide
oxygen, and control erosion.

12. Ways of biodiversity that
helps human
Plants absorb greenhouse gases and help
stop global warming.
It is easier for biodiverse ecosystems to
recover from natural disasters.
Healthy biodiversity of species can provide
a variety of food (like meat and produce).
Many of our medicinal drugs come from
plants.

13. Ways of biodiversity that
helps human
All of our wood products come from nature.
We can learn more about our earth by
observing a diverse ecosystem.
Many recreational areas benefit from a
healthy ecosystem, which promotes tourism.
Biodiversity is beautiful and should be
enjoyed.
These values are free to us, but as we lose
biodiversity the cost of replacing these would
be very high!

14. What are the threats of
biodiversity?
There are a lot of threats to biodiversity.Here
are some of the major threats:
1) Using up natural resources before they can
be renewed (over-fishing in oceans, or
over-harvesting trees on land)
2) Habitat destruction like clearing forests or
draining wetlands for towns or agricultural
purposes

15. Threats
3) Releasing invasive species into foreign
ecosystems (like the cane toad in Australia or
the zebra mussel in the Great Lakes)
4)Any kind of pollution (water, air, soil, etc).
5)Failure of food chains.
Those are some of the big threats to biodiversity,
and some of those are threats to other things, too.
For example, using up natural resources can hurt the
world's economy.

17. Where is biodiversity found?
 Biodiversity is found wherever there is life which is
all around the world. However, some parts of the
world are more biologically diverse than others.
For example, the Great Barrier Reef contains many
different species: 1500 fish, 350 kinds of hard
coral, 5000-8000 mollusks, 22 species of sea
birds, and many more animals species. Over 30
different species of marine mammals and 6 species
of sea turtles are listed as threatened.

18. Where is biodiversity found?
In the Amazon Rainforest, over 500 kinds of
mammals, 175 lizards and over 300 reptile
species live there. About 1/3 of the world's
birds live there and about 30,000,000 insect
types can be found there.

19. Where is biodiversity found?
The African Savannah has about 45 species of
mammals, about 500 bird species, and 55
species of acacia (plants that are shrub-like).
The savannah has the largest diversity of
hoofed animals in the whole world. Overall,
biodiversity is found all over the world, and
even in your own backyard.

20. CONCLUSION:A:
Here are a few things you can do to help
biodiversity:
 Put out bird feeders, bird bathes, and houses.
 Put up a bat house.
 Be careful not to buy coral, ivory, or tortoise shell
products. They come from endangered species.
 You can volunteer at a nature center, park, or a
zoo.
 Add mulch to soil to prevent erosion.
 Composting can add nutrients to your soil.

21. Buy organic produce.
Don’t use pesticides; they can kill plants and
animals.
Stop junk mail to save paper and protect our
forests.
When renovating your house, buy FSC approved
wood, because it is harvested in ways that
don’t harm the forests.
Use cloth napkins.
Recycle old newspaper and buy recycled paper
products.
Use e-mail since it saves paper.

22. B:Our trip to a Biodiversity
Plant at Nagpur
At Gorewada we found the beautiful diversity
of plant species.
We also discovered about variety of birds
migrating in that region.
We also learnt about various spices that they
grow there.
