Yes, the Chinese are infuriatingly irresponsible.
But so are we. As in NZers and Aussies.
We are not as bad. But only just.
Nz has a pretty shocking record for industrial filth and general pollution - it's just because we have such a tiny country that we can get away with blue murder. You probably know about the state of fish stocks in NZ waters. Yes, we've had poaching from Russian, Korean and Jap (I think) vessels, but the kiwi boats had a rape and pillage mentality as well.
I worked on longliners and factory boats a while back, and the amount of fish dumped just made your blood boil.

So what I'm trying to say is it's easy, and justified, to get really pissed off at countries like China and India, but we aren't exactly squeaky clean either.
Illuc ivi, illud feci.
Buggrim, Buggrit.
