write a letter in about 120 words to your friend advising him celebrate diwali without crackers.

i think u definitely know the formats n all.. so i'll start with the content :-
and im writing to ''Sonu'' , u may use any name of ur wish !

Dear Sonu,
                How are you ? How are aunty and uncle ? i hope that this letter finds in the pink of ur health ! 
 Recently, i was goinng through a survey about pollution and You will be shocked to know that India is also one of the most polluted country. Then I thought that it must be like land pollution and all, but more shocking was that we are also ahead in Air and Noise pollution ! And the given reasons were Vehicles and Crackers ! 
I suddenly realized that its definitely true, b'coz the way we burn crackers in Diwali and other family festivals like wedding, retirement party etc... it definitely causes alot of Noise and Air pollution ! I know that you love to burn crackers.. but you see my friend how harmful it is for us and for our comming generations ! So, I would not say completely stop burning crackers but burn those wich are eco-friendly and causes less noise pollution ! 
Hope you will listen to your best friend and this diwali lets all be eco-friendly ! :D :D
Give my greeting to aunty n uncle and lots of love to Anurag !
Yours'
Aman ! 

Hope this helps ! :)
