Even the air we breath

"They have taxed and made a profit even from the air we breath"

Actually, the sole reason is the precautionary principle, which is not a physical or scientific principle, and if we would adopt it, there wouldn't be any activity, because in every activity there exists a risk. We shouldn't go out, because there is risk, and we couln't stay in, because there is risk, even there. there are so many domestic accidents...
