When I was a kid in rural Louisiana, we didn't have an "ecosystem." There were lead pipes, copper pipes, soldered gutters for water into the cistern. Agrichemicals in the air very often that the rain washed into our water. DDT, Chlordane, Arsenic, HeptaChlor, leaded gasoline, lead based paint, creosote wood products for fence post and piers. We burned our own trash. And of course the brakes, gaskets, insulation and all was asbestos. And of course we had no air conditioning at all and butane for hot water heater, stove and space heaters. Now California leads us a merry chase to do away with all those bad things and will replace them with windmills, solar electric cars with huge heavy metal batteries. Where does the tire material go as tires wear out? HaHa We are fools...
