This is so flipping stupid that it forces me to use the word flipping. The entire atmosphe's air should be clean,and not poluted to the hilt, I mean the toxins that a lot of cars and businesses realese are very dangerous,. but no.... lets just keep adding more of them into the air we breathe, The polluted air is a fine comparrison to that of pseticides to weeds and small insects. The other day my friend was at work when he walked by a room the was getting sprayed with deadly chemicals, when the guy spraying them turned around and completly spayed my friend with DEADLY CHEMICALS!!! what is this worls coming to?!! so basically to sum this long rant up... We need all the clean air we can get you crazy person!!
