Answer 2

Hello friends, I wish to speak on the topic of relevance to all of us in the 21st century.

 Introduction:

Our Environment is a very essential part of our life.  It is the main source for us to live  in and get food from, to eat, play, work, enjoy, walk, breath, hear or drink.  The environment is basically the atmosphere, and surrounding geographical area.  We know very well that quality of our life depends on our environment. 

 Let us question ourselves, who spoils the environment ?

           Long ago, people lived adapting themselves to the environment and could not harm the environment.  In these days we are harming and degrading the environment, and thus indirectly harming ourselves.  Power of the technology and science has enabled the man to exploit the environment for selfish and indiscriminate use.   This is creating problems for everyone. 

 The causes of worry are:  

1.  Deforestation,  

2.  Growth of population and Rapid urbanization  

3.  Loss of biodiversity  

4.  Air pollution (greenhouse gases), drinking water pollution, river pollution by mixing poisonous chemicals, plastics.

5.  Global warming and Depletion of ozone layer  

6.  Depletion of underground water, oil and gas reserves and natural resources like minerals. 

 Effect of our irrational or selfish actions:

      Famines, untimely rains, cyclones, polar ice melting, ecological imbalance, increase in erosion of land, less protection from UV radiation, diseases and life amidst pollution and so on.

Let us know what we have to do :

     We have to adapt our manufacturing and domestic product usage processes to the  environment.  We must use reducible, reusable, regenerative and recyclable techniques.   The  governments of various countries and the United Nations Organization must take up actions at a global level.  

   Long term planning and monitoring of actions of private corporations is needed.  The young must be educated to live in harmony with environment rather than exploit it.  

Conclusion: 

      Each of us has a role and responsibility to protect our environment.  Only that saves our race on Earth.
