Answer 2

Answer:

Dear Sir,

I heard that the department of environment had decided to clear the major portion of the forest for making a flyover and expressway. I would request you all not clear the forest area as it prevents soil erosion and provide many things. It also provides with watershed protection and are homes to many animals.  

Thanking you,

Yours truly,
