This is a presentation made by Sarthak Bhardwaj.This ppt tells about the World Nature Conservation Day.I hope that this presentation would educate the today's youth that how important environment is.

3. World Nature Conservation Day recognizes
 a healthy environment is the foundation for a
stable
 productive society
 to ensure the well-being of present and
future generations
we all must participate to protect, conserve,
and sustainably manage our natural resources.

4. To keep the balance in the natural world, we must also help
various species to continue to exist.
A report from the global conservation organization World
Wildlife Foundation suggests that since 1970, the pressure
that we exert on the planet has doubled and the resources
upon which we depend have declined by 33 percent.
Despite the efforts put into conservation by organizations and
conservation activists, their work has been undermined by
those who have interests.

6. • Also called global warming
• Refers to the rise in average surface
temperatures on Earth.
• An overwhelming scientific consensus
maintains that climate change is due
primarily to the human use of fossil fuels,
which releases carbon dioxide and other
greenhouse gases into the air.

7. • Deforestation is clearing Earth's forests on a
massive scale
• Resulting in damage to the quality of the land.
• Forests still cover about 30 percent of the world's
land area, but swaths the size of Panama are lost
each and every year.

8. • Pollution is the introduction of contaminants
into the natural environment that cause
adverse change.
• Pollution can take the form of chemical
substances or energy, such as noise, heat or
light.
• Pollutants, the components of pollution, can
be either foreign substances/energies or
naturally occurring contaminants.

9. The generic definition is:
• The number of species in an environment
• The number of individuals in each species.
• To put it simply, it is the number of different
species in one area and the quantity of
each of these species.

10. • Dead zones are hypoxic (low-oxygen) areas in
the world's oceans and large lakes
• Caused by "excessive nutrient pollution from
human activities coupled with other factors
that deplete the oxygen required to support
most marine life in bottom and near-bottom
water. (NOAA)."

11. Definition of population explosion. :
• a pyramiding of numbers of a biological
population;
• especially : the recent great increase in human
numbers resulting from increased survival and
exponential population growth.

12. The definition of sea level rise-
• When ice on land, such as mountain glaciers or
the ice sheets of Greenland or Antarctica, melts,
that water contributes to sea level rise.
