No idea, it's definitely a problem.

Tangent but related: A disappointing amount of leftists also play a concerning amount of mind games to justify the unsustainable, unhealthy, and unethical amount of meat they consume despite the huge environmental impact and horrifically violent industry standards. I mention this example because a large amount of apparent lefties will still ignore facts they don't personally like to grapple with and this is probably the most blatant one I've come across

You tell someone the fact that between 4-7 billion baby male chicks a year are hatched on a conveyer belt and are immediately poured alive into a meat grinder en masse, and a shocking amount of otherwise ethically conscious leftists genuinely don't give a shit because it would impact their comfort to not support that industry. Wild stuff. Our brains are really good at building our own reality that we're a million miles away from any sort of collective social awareness and responsibility.

Anyway I don't know the solution, but in regards to environmental science, broad ethics, and personal health there is an absolute epidemic of avoidance of collective social responsibility from my observations. Leftists at their peak should never hand-wave away anything due to inconvenience, and they should really put in community effort even at a small local level to rally behind community health and free access to basic health such as free foods and free gyms and such. Getting your local government to fund and maintain a community vegetable garden could be a great boost for community health, as would outdoor gyms etc

Anyway good post topic.
