TFA makes a fair point that some authors will talk about "chemicals" as having specific toxic effects on certain species, without specifying which chemicals they are talking about. She is not arguing against environmentalists, though. Clearly when people complain about chemicals in the environment, they are talking about man-made toxins that need to be regulated better, not about dihidrogen monoxide or whatever other smartass examples people want to come up with. The fact still stands that there are A LOT of toxins in our environment, and that number is growing at an alarming rate.

got it, thank you!
