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

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