Carbon is only bad when there isnt enough trees to filter it, and if the government would stop spraying crap in the air to block the sun, again a precious commondity we all Proud Parrot Dad Bird Lover TShirt need to survive, they wouldnt be killing off not only the trees but us too, you can literally see the trees dying from what they are spraying, not really sure why or what is going threw their heads, but it is killing them also.
