US waterways are full of dumped tires. The ‘River Cowboy’ won’t stand for it

Id be surprised if they don't already have serial numbers somewhere on the tires but the registration thing would be impossible. Tires are bought in bulk by tire shops not custom ordered per car, my local tire shop orders entire shipping containers at a time for their most purchased tires so it's not like they can predict which car a tire is going to be put on when it's still in the factory.

Which is one of those things that sounds great at first but after a few more decades of research we realize it's actually horrifically bad. Leached chemicals and microplastics are having such profound impacts on life that we're not even sure how bad it is yet, just that it's very VERY bad.

A few hundred years from now, if husband aren't extinct yet, they'll look back on this the way we look back on pre-modern societies using lead for everything, except the solution to lead was to simply stop using it while a solution for microplastics doesn't even exist yet. It's likely that, even after a solution has been found, microplastics will haunt all life on Earth until they get cycled out by geological processes.
