It's not just about carbon. It's about toxic sludge byproducts being used in fules, transported by truck and rail, being stored in tanks, emitting voc, fymalihide, and tons of random waists in the air in a condensed area. Luckily it's spaced out better in America than China, but all you have to do is look around your back yard and open your eyes to the new mega plants, and research the companies, and just watch when they operate, most of the time smok stacks are going full force at night when normal people sleep. There is a reason for that.
