WHAT IS BIODIVERSITY?
BIODIVERSITY AND ITS IMPACTS
Climate change refers to any significant change in the
measures of climate lasting for an extended period of time. In
other words, climate change includes major changes in
temperature, precipitation, or wind patterns, among other
effects, that occur over several decades or longer.
Biodiversity is the shortened form of two words "biological"
and "diversity". It refers to all the variety of life that can be
found on Earth (plants, animals, fungi and micro-organisms)
as well as to the communities that they form and the habitats
in which they live.
5. CLIMATE CHANGES
The term "climate change" is often used to refer specifically to
anthropogenic climate change (also known as global warming).
Anthropogenic climate change is caused by human activity, as
opposed to changes in climate that may have resulted as part of
Earth's natural processes.
Food and fresh water disrupted
Millions of people displaced
Disease altered dangerously
17. 1916 - The term biological diversity was used first by J. Arthur
Harris in "The Variable Desert," Scientific American, "The bare
statement that the region contains a flora rich in genera and
species and of diverse geographic origin or affinity is entirely
inadequate as a description of its real biological diversity."
1975 - The term natural diversity was introduced (by The
Science Division of The Nature Conservancy in a 1975 study,
"The Preservation of Natural Diversity.")
1980 - Thomas Lovejoy introduced the term biological
diversity to the scientific community in a book.It rapidly became
18. 1985 - According to Edward O. Wilson, the contracted
form biodiversity was coined by W. G. Rosen: "The National
Forum on BioDiversity ... was conceived by Walter G.Rosen ... Dr.
Rosen represented the NRC/NAS throughout the planning
stages of the project. Furthermore, he introduced the
1985 - The term "biodiversity" appears in the article, "A New
Plan to Conserve the Earth's Biota" by Laura Tangley.
1988 - The term biodiversity first appeared in a publication.
The present - the term has achieved widespread use.
20. Distribution of Biodiversity-Flora and Fauna
diversity depends on
Presence of other species
Most of the biodiversity concentrated in tropical region
21. Ecological Services:
Balance of nature
Regulation of climate
Degradation of waste
Cycling of Nutrients
Detoxification of soil
Stabilization of land against erosion
Maintenance of soil fertility
22. Snakes feed with rats, if we kill
snakes we will be end up living terrible rat
23. Conservation of Biodiversity
Conserving Biodiversity in protecting habitats
In Situ Conservation
Ex Situ Conservation
Seed bank, Gene bank, Pollen bank, DNA bank.
Restoration of Biodiversity
Biodiversity is our life. If the Biodiversity got lost at this rate
then in near future, the survival of human being will be
threatened. So, it is our moral duty to conserve Biodiversity as
well our Environment. Long- term maintenance of species and
their management requires co-operative efforts across entire
Usually it is used in a context that stresses the need for
attention on our living environment and the sustainable use of
