Ok, that's an excellent sentiment, but utterly worthless in the real world. People will buy what is available and what is cheap. A handful of people choosing to be conscious with what they purchase is a drop in the bucket compared to what the masses will do.

I get it. Convincing the people to not buy stuff that pollutes should be the easy route, but it's not. And unfortunately we don't live in the world of "it should be this way", we live in reality. And in reality, the only real way to stop pollution heavy products from being sold is to go after the companies making them directly. Boycotts alone will not work because, again, as long as the products are available and cheap, people will buy them; morals be damned.
