Sure it would change something but it wouldn't be enough to actually change the outcome. Companies are polluting way more then those over 8 billion people are. But yet everything governments come up with is you have to do this you have to do that. I mean growing up recycling was pushed hard on us. And look at the scam that turned out to be cause companies where just sending it to third world countries or dumping it in the landfills. Not to mention the best one is reduce but that hurts corporate profits.
