Nice que..
well i think it is true that if one grows one tree then we can make our city green but on the other hand we must have to make sure that no one cuts tree for once personel purpose.. otherwise we wont make green eventhough one grows more than one tree!!!
And only growing trees is not enough for that.
Many other things also must be given equal importance
such as we should minimize the use of those products which are harsh to an environment...we should take care of natural resources and many more.....
