I think it would take an incident that kills a bunch of people that effect global economies for anyone care.

Everyone dies in a small Vietnamese town that makes t-shirts on the cheap. It wouldn't be the people that died that would matter, it would be the stop of cheap production. If the work can be moved elsewhere, their deaths are unimportant.

The world is a meat grinder for the rich and powerful. Eventually most of us will die because of it, the trajectory has been that way for so long. We did stop the hole in the ozone, but only because we developed technology to reduce factories producing CO2 not because we were willing to turn them off.
