This document discusses biodiversity, including its distribution across terrestrial, aquatic, and aerial environments. It notes that biodiversity provides many benefits but is facing threats from habitat loss and human activities. Specifically, 30% of natural species are predicted to go extinct by 2050 due to causes like deforestation, pollution, climate change, and overhunting. The document calls for conservation efforts like banning forest destruction, prohibiting hunting, planting trees, and protecting animal habitats in order to preserve endangered species and maintain ecosystems.

 CONCLUSION

3.  BIODIVERSITY IS THE DEGREE OF
VARIATION OF LIFE FORMS WITHIN A
GIVEN ECO SYSTEM OR A PLANET
 IT CONSISTS OF MILLIONS OF LIFE
FORMS ON THE EARTH SPREAD UNEVEN
ON EARTH
 THE YEAR 2010 IS DECLARED AS THE
INTERNATIONAL YEAR OF
BIODIVERSITY

4. BIODIVERSITY IS NOT EVENLY
DISTRIBUTED.IT DEPENDS UPON
CLIMATE,ALTITUDE,SOILS AND
PRESENCE OF OTHER SPIECES.IT
CONSISTENTLY MEASURES HIGHER
IN TROPICS THAN IN POLES.
THE FOLLOWING TABLE PROVIDES
MORE INFORMATION ABOUT THIS
TOPIC.

5. DISTRIBUTION
TERRESTRIAL AQUATIC ARIEL
(LAND SPIECES)(WATER SPIECES) (AIR SPIECES)

6. DISTRIBUTION

7. THE ECOSYSTEM HELPS US IN MANY
WAYS
 HUMAN BENEFITS AND HUMAN HEALTH
BIODIVERSITY IS RESPONSIBLE FOR AIR
QUALITY,CLIMATE,WATER PURIFICATION,POLLINATION
AND PREVENTION OF EROSION.THEY ARE THE SOURCES
OF MANY DISEASES AND MANY MEDICINES TOO.
 AGRICULTURE
THEY ARE VERY USEFUL IN THE PRODUCTION OF A CROP.
THEY CARRY OUT DECOMPOSITION AND NITROGEN
FIXATION ETC

8.  BUSINESS AND INDUSTRY
THEY PROVIDE US WITH BUILDING MATERIALS,
FIBRES,DYES,RUBBER,OIL,TIMBER,PAPER,
FOOD,MEDICINAL RESOURCES.
 OTHER USES
IT PLAYS A PART IN REGULATING THE CHEMISTRY OF
OUR ATMOSPHERE BY PURIFYING WATER,RECYCLING
THE NUTRIENTS AND BY POLLINATION

10. ACCORDING TO THE GLOBAL TAXONOMY
INITIATIVE THE TOTAL NUMBER OF SPECIES ARE
DENOTED AS BELOW
 10-30 MILLION INSECTS
 5-10 MILLION BACTERIA
 1.5 MILLION FUNGI
 1 MILLION MITES
MANY SUCH NEW SPIECES ARE
DISCOVERED INTHIS NEW WORLD .

12. DURING THE LAST CENTURY,DECREASES IN
BIODIVERSITY HAVE BEEN INCREASINGLY
OBSERVED. 30% OF ALL NATURAL SPIECES
WILL BE EXTINCT BY 2050. OF THESE ABOUT
ONE EIGTH OF KNOWN PLANT SPIECES ARE
THREATENED BY EXTINCTION. ABOUT
1,40,000 SPIECES BECOME EXTINCT BY ONE
YEAR.ONLY A SMALL NUMBER OF SPIECES
EVOLVE EACH YEAR. BUT THE DESTRUCTION
IS MORE.

14. MOST OF THE SPIECES EXTINCTION FROM 1000AD TO
2000 AD IS DUE TO HUMAN ACTIVITIES. THEIR
HABITATS ARE REFORMED AS CROPLANDS,PASTURE
LANDS,ORCHADS ETC. THE SIZE OF THE HABITAT
AND THE NUMBER OF SPIECES ARE SYSTEMATICALLY
RELATED.MORE SO THE RIVERS WHICH ARE HOME
FOR MANY SPICES ARE POLLUTED BY HUMAN
ACTIVITIES.HYBRIDISATION,OVER HUNTING,CLIMATE
CHANGE HOLOCENE EXTINCTION ARE THE MAJOR
CAUSES FOR THEIR EXTINCTION.DECLINE OF FOREST
ALSO RESULTS IN GLOBAL WARMING WHICH
THREATS THE WHOLE WORLD NOW.

15. CONSERVATION OF THE SPICES
BECOMES A MATTER OF CONCERN
DURING THE 20 TH CENTURY. MANY
STEPS AND EFFECTIVE MEASURES HAVE
BEEN TAKEN TO CONSERVE NATURE.
THEY HELP US IN MANY WAYS, BUT IN
TURN WE ARE KILLING THEM. IF
PLANTS WERE NOT THERE WE ALSO
WILL NOT BE HERE.AS THE ECO SYSTEM
IS INTERDEPENDENT,THER IS A
NECESSITY TO CONSERVE THEM.

16. SOME STEPS TO CONSERVE NATURE
 DESTRUCTION OF FOREST SHOUD BE
BANNED
 HUNTING SHOULD ALSO BE BANNED.
 PLANT MORE TREES.
 ANIMALS SHOULD NOT BE ILLTREATED.
THEY SHOULD RETAIN THEIR HABITATS
AND ALLOW THEM TO BREED FREELY.
BY FOLLOWING THESE MEASURES THE
ENDANGERED SPECIES CAN BE RECOVERED.

17. WE SHOULD CONSERVE NATURE
THERE BY PROTECTING OUR
FRIENDS AND FOES. THE WORLD
IS NOTHING WITHOUT THEM. AS
THIS IS YEAR IS CELEBRATED AS
THE INTERNATIONAL YEAR OF
BIODIVERSITY IT IS OUR DUTY
TO CONSERVE THE SPIECES.
