evergreen is always life,but do we think about the polution we cause to innocent plants,water and animals that leave in our care. factory,companies,societies,communities,town,cites,countries. lets be wise and think of tomorrow's generation.because what was alive 500 years ago we can not see,feel or touch them any more. we must start to develop and educate the world now. climate change for good is required not for the bad as at now. think twice every concern person.
