I don't see how it's observably not the case when my mother is working in a hospital where people are kept alive for decades just for the slight chance that medicine might evolve enough to cure them or they just wake up one day; when they are spending extraordinary amounts of money and time of dozens of researchers and doctors on experimental treatments, etc. I don't understand how vehicles or pollution change anything. I never said there are no bad actors, there are in every civilization, and there are compromises you need to make but that doesn't mean you would not do anything to save someone. Awareness about pollution and its effects is just starting to exist. We didn't think it's bad a few decades ago.
