Exactly, and then it flows down the rivers into the Pacific ocean and swirls around to the US or sinks and poisons the fish that are caught and sold to US. Hm.

(For those dislike any and all criticism of, well, China, a possible solution would be to require that trade partners implement and enforce similar levels of environmental regulations on manufacturing so that international trade is not just "exporting pollution". This is not simple though because China has a habit of fake-certifying things (for example much Chinese-grown "organic" food is organic in certification alone). So to work in reality and not theory, this would involve non-Chinese inspectors throughout the country with full access to inspect things, which would probably not be acceptable to Chinese State officials. In reality, things will continue as they have been going until the oceans can no longer support life, followed by massive extinctions of other animals such as humans and all other species whose ecochains have links relying on healthy ocean functioning to live.)

I'd love that, but you do realize that it would stop 'outsourcing' pretty much dead in its tracks. (not a bad thing by itself).

This will also immediately be reflected in the sticker price of the goods.
