By 2050 air pollution will be the biggest cause of premature death. What is interesting though is that already it is a bigger issue than malaria. Now, no one can possibly have missed fund raising campaigns against malaria. As it turns out, air pollution, inside and outside, are bigger issues. Yet, how much is being done against that? Lots of conventions and commissions and other words on C but because you have big corporations and powerful people who choose to believe its bullshit people are dying.
