FYI, I am sure they still have acid rain in CHINA.
From all the coal fired electrical generation plants.
Also, keep in mind that we really did pollute the air and water back in the 1930s-1980s than we do today.
The river in Cleveland actually caught on fire because all the crap they were dumping in it. That all spilled into Lake Erie and Ontario.
I grew up in Buffalo. There used to warnings on the radio that pregnant women should not consume the fish out of Lake Ontario more than once a week. That is because the amount of MERCURY in the apex predator fish species like Lake Trout.
In Niagara Falls, NY they buried thousands of barrels of chemicals then built a school and neighborhood on top of it.
50% of the people living there got cancer.
It was called Love Canal.
The EPA really did clean up the environment in the USA.
I can think of three Super Fund sites within ten miles of where I live right now in NH. One company made hand tools. They dumped all sorts of chemicals out back. Another made paint. The ground around there is toxic from the stuff they poured into it.
Another is a plastics company that screwed up the water table so bad near their plant that they had to pay to put every house/condo on city water.
“The river in Cleveland actually caught on fire because all the crap they were dumping in it. That all spilled into Lake Erie and Ontario.”
That story is not really true. Another exaggeration made up by the enviros. Yes, the river was badly polluted but what actually happened was a pile of trash caught in a backwater was ignited by sparks from a passing train. That picture they always show of the fireboat hosing down an oilslick fire on the river was from the 1950s.
