2 BIOLOGICAL DIVECITY v BIO DIVERSITY THE VARIETY

2. BIOLOGICAL DIVECITY v BIO – DIVERSITY : THE VARIETY THAT WE SEE IN THE LIVING THINGS THAT EXIST ON THE EARTH IS CALLED BIO-DIVERSITY. v THOUSAUNDS OF SPECIES PF ANIMALS & PLANTS CAN BE SEE TO THE SURFACE OF THE EARTH THERE IS AN ABUNDANCE O VARITY IN THERE SHAPES , SIZES & BODY PARTS. v SIZED. v EATING HABITS.

v THERE IS ALSO MUCH VARIETY IN THE BODY STRACTURE , LIFE PATTERNS & HABITATS OF SPECIES BELONG TO THE SAME CLASS v ENVIRONMENT IS ALSO AN IMPORTANT FACTOR THAT BRINGS ABOUT THIS BIOLOGICAL DIVERSITY. v ATUATIC LIVING THINGS WHETHER THEY LIVE IN PONDS , RIVERS , LAKES OR SEAS , ALL SHOW A GREAT AMOUND OF VARITY. v THE IMPORTANCE OF THE CONSERVATION OF BIO-DIVERSITY

v. THE NEED OF ALL LIVING THINGS INCLUDING THOUSE OF HUMAN BEINGS ARE MET BECAUSE OF THE DIVERSITY OF LIFEFORMS. THAT IS WHY BIO-DIVERSITY IS IMPORTANT FOR THE EXISTENCE OF LIVING THINGS. OUR BASIC NECESSITIES OF FOO CLOTHES & SHELTER , OTHER IMPORTANT NECESSITIES LIKE MEDICINES ARE MET ONLY BECAUSE OF BIO-DIVERSITY. v. ENVIRONMENTAL IMPORTANCE : IN SHORT , IT IS ONLY IF TH BALANCE BETWEEN THE NUMBER OF PLANTS WHICH ARE PRODUCERS , & THE NUMBER OF HERBIVORES , CARNIVORES , ALSO OF DECOMPOSERS SUCH AS BACTERIS IS MAINTAINED , THAT NATURE’S CHAIN CAN CONTINUE TO SURVIVE. v REASONS FOR THE DECLINE IN BIO-DIVERSITY : -

THE EXPLOSIVE R AT WHICH THE POPULATIONS OF OUR COUNTRY IS GROWING I THE MAIN REASON FOR THE DECLINE IN BIO-DIVERSITY. v POLLUTION IN THE ENVIRONMENT IS ANOTHER CAUSE FOR THE DISAPPEARANCE OF MANY SPECIES. THE RISING TEMPERATURE OF THE EARTH CAN PROV DANGEROUS FOR SOME RARE AND SENSITIVE SPECIES THAT CA ONLY SURVIVE IN CERTAIN SPECIFIC CONDITIONS. TO CONSERVE BIO-DIVERSITY, IT IS NECESSARY TO PROTECT AND CONSERVE ENDAGERED SPECIES. v PROTECTION OF RARE SPECIES : VARIOUS OTHER MEASURES ARE ALSO BEING UNDERTAKEN

SOME OF THEM ARE GIVEN BELOW : Ø CREATING NATIONAL PARKS AND SANCTUARIES. Ø DECLARING SOME AREAS AS RESERVED BIO-DIVERSITY ZONES. Ø UNDERTAKING SPECIAL PROJECT TO NURTURE SPECIFIC SPECIES. Ø TO NURTURE SOME SPECIES OF ANIMALS AND PLANT IN ZOOLOGICAL OR BOTANICAL GARDENS , RESPECTIVELY. Ø TO COMPILE AND DOCUMENT TRADITIONAL KNOWLEDGE. v LOCAL SPECIES SHOW MANY CHARACTERISTICS SUCH AS RESISTANCE TO DISEASE , SURVIVAL IN ADVERSE CONDITIONS , SHORTER LIFE-CYCLES. v SEED BANKS HAVE NOW BEEN STARTED FOR THIS VERY

PURPOSE. THERE ARE GENE BLANKS FOR PRESERVING THE GENES OF LOCAL VARIETIES. ALL THIS HAS BECOME POSSIBLE DUE TO ADVANCES IN THE FIELD OF BIO-TECHNOLOGY. v RESERVED BIO-DIVERSITY ZONES : A TREATY FOR PROTECTING PLANTS & WIELD ANIMELS IN DANGER OF EXTINCTION BECAUSE OF INTERNATIONAL TREATY HAS COME INTO FORCE SINCE 1975. THIS TREATY REGULATES THE IMPORT & EXPORT OF ALL KINDS OF WILDLIFE.
