Ditto. Pollution -- like trash mountains -- are a problem. However, more CO2 is good, so more of those emissions is great. Most don't realize that we are in a CO2 famine. This is why commercial greenhouses pump lots of CO2 into them. And those rumors about plants growing better when you talk to them ... well that's true for a different reason. Plants love your breath because it's full of CO2. But they will only grow better by breathing on them in the daylight, since they use sunlight (photosynthesis) to process the CO2.
