We got rid of lead products because governments put out new regulations that prevented companies from making products with lead, not because the population collectively decided not to buy products with lead in them. If companies had been allowed to continue making lead products, they’d have done so, and people would have continued buying them despite the science pointing to them being bad for you.

Companies will do whatever is profitable unless prevented from doing so by regulations, and people will buy what companies sell because most people don’t know, and don’t have the time to figure out what products they buy are harmful to themselves and others. Even when they do, they often don’t have the wealth to make a change to buying safer, more expensive products.

“How society works” is that people have to buy products to survive, and often have little choice among what products they can afford. If we want companies to start lowering their emissions, we need to force them to do so with regulations, just like we had to do with lead.
