Just as the pandemic accelerated global cooperation and change, so could the climate issue. If the US wanted to shut down this problem, regulators could find the key spot to put a bullet into. Ideally the US would take the responsibility that comes with globalism after nuking the world with trash.
Trash is how I view everything I buy. I'm walking into a store to buy trash. It doesn't matter that I still wear a belt daily which I have had for 15 years and much of my clothes are seriously straining from overuse. It still goes to trash eventually. If I take it to my grave, then I'm trash wrapped in trash. When I first stayed in a developing country, there was no trash service for much of the region. If you wanted to get rid of something, you burned it. Today I do all my shopping considering what it would be like to burn it. Car shopping would be so much fun.
Don't think it matters what we do individually. This needs to be an urgent thing taken at levels where people actually have power to change things.
Also, I think the issue is that this is essentially a scheme to cheaply get rid of trash. You could probably pay these importers to take the trash and it would still be worth it. "You mean, you'll pay us to take our trash?! Thank you so much for solving that nightmare of a problem for us. This was looking REALLY expensive for us to deal with in our own country."
