People often say that about climate change but isn't it fairly general and obvious that widespread problems hurt poor people the most? In a food shortage, the people who can't afford for food starve first. In developed coastal land shortage, the people who can't afford mitigations have their lives disrupted the most. When a war happens, the people who can't afford to flee get caught up in it. People who can't afford to move out of a high crime neighborhood are more often victims of crime. Disease causes more harm to people who can't afford medicine.
Is being poor really more desirable for anything? Perhaps instead of worrying about global warming, we should solve poverty, then they won't be affected so badly.
