We should all come out for 1 day in the week and every lerson should plant 10 trees
in this way one man will plant 40 trees in 1 month
and in one year 1 man will brush 480 trees
think of this, when all the people's will brush this trees in the same way.
then how many trees brush in 1 year .
think about it , this is very good way to plant trees , and save environment
i hope you like my tip.
thankyou dear sir/madam
