Solve this: a) 'Down to Earth' an environmental awareness magazine has launched a marathon ' clean your city campaign' As an active participant, write a speech on urging students to participate in the campaign.

Dear Student

Dear fellow campaigners
We are all present here to take part in this important mission of conserving our environment. Mother nature has put up with outrageous behaviour from man and has started to strike back out of exhaustion. Her frustration reaches us in the form of global warming, drought and other natural disasters. The air is polluted with all sorts of gas emissions that have resulted from the scientific advancement of man. The water has been polluted by industrial wastes and other human waste materials. What about land? It is so much polluted that farming has become next to impossible in many parts of earth. You and I know that this cannot go on for long.
So what do we do? Obviously cleaning! But where do we start? Like every good things, it has to be started from the grass root level.  We must start the cleaning campaign from our houses and must spread it to our city which is the only possible solution.
But then the question arises what to do with the waste. We must go around popularizing the idea of handling the waste at sources itself. Bio gas plants are the most effective methods to do this. Moreover people should be encouraged to use bio-degradable  materials. 
I conclude my words my urging every one to spread awareness and need of protecting the environment 
Thank you.
