The problem is the Environmentalists in name only that are actually just political activists. They really don't care who they kill. They just want their imaginary causes to be victorious.
US Environmentalists know that shipping products overseas cause 2 things:
1) Mostly unregulated pollution
2) Lower Price. Lower Quality. More trash and consumerism.
You don't fix cheap Chinese junk. You buy a new one.
So you double the manufacturing pollution. Double the shipping pollution. Double your trash pile.
All of that would alarm someone really interested in the environment.
They would want it made in the USA and to be of the highest value to prevent waste.
