3. Why conserve biodiversity?
Indicators of healthy ecosystem
Edutainment
We share and affect their locality
All organisms play an important role
Boosts ecosystem’s productivity
Healthy ecosystems can better withstand and recover from a
variety of disasters
4. Primary strategy
Maintain intact (viable) landscapes.
Reverse declines.
Recover threatened species and ecological communities.
Control emerging threats.
5. Threat to biodiversity
Habitat destruction
Habitat fragmentation
Pollution
Over exploitation
Introduction of exotic species
Diseases
Poaching of wild life - make the species distinct
6. GMO
Virus, bacteria and fungi tolerance
Hybrid (golden rice)
Drought and flood tolerance
Disease resistance
Climate change adaptation and production
Herbicides, pesticides, insects and fertilizers resistance
High yield and fast growth
Delayed softening in fruits – prolonging storage life.

8. Cloning
Management of endangered species.
Mutant organism production will lead to evolution.
Retrieval of old species.
Many clones can be produced in short duration.
Offspring is superior than the parent.
Undo the harms that humans had done earlier.
Restore ecosystem and preserve biodiversity.

10. National parks
Protected environment to bio species.
Earliest national parks are: The Yellowstone National Park in
USA and the Royal National Park near Sydney, Australia.
WCMC has recognized 37,000 protected areas around the
world.
515 wildlife/animal sanctuaries in India (including
biosphere reserves and forests),
48 are governed by Project Tiger.
Forest preservation is required to preserve
species in their habitat.
11. Biosphere Reserve Programme
Protection of land or coastal regions,
ecosystems and the genetic resources.
Concept was launched in 1975
(UNESCO).
May 2002 - 408 biosphere reserves
dispersed in 94 countries.
Functions : conservation, eco
development, research.

13. Cryopreservation
In vitro conservation is done in liquid
nitrogen at a temperature of -196°C.
Vegetative propagated crops, e.g.,
potato.
Either by very rapid cooling (seeds) or by
gradual cooling and simultaneous
dehydration (tissue culture).
Stored for long time.
14. Seed gene banks: easiest way to store germplasm of
wild and cultivated plants at low temperature.
Field gene banks: preservation of genetic resources is
being done under normal growing conditions.
15. Botanical Gardens
They benefit pollinators like
butterflies, honeybees and birds.
Linking plants with the well being of people and also
helping conserve indigenous and local knowledge.
33 government Botanical Gardens (Universities have
their own botanic gardens).
1500 botanic gardens world wide preserving more
than 80,000 species.
Herbarium-plant specimens for research studies.
16. General measures
Important and endangered species should be identified.
Preservation of unique eco systems.
Avoiding of poaching and hunting.
Reducing pollutions.
Public awareness and education.
NGO.
Prevention of over exploitation of natural resources.
Environmental laws should be strictly followed.
17. Steps that an individual can take
Sugar for ants
Inform corporation about street dogs
Kitchen garden
Terrace garden
Back yard
Avoid pesticides
Honey comb
Fish tanks
Water for birds
