I do care, I think society should pay more attention to climate change and environmental protection. Also I think that the spread of nuclear technology and nuclear weapons is a huge problem for national security and the safety of the entire planet. Not so long ago I found info about best detectors here https://ecotestgroup.com/products/ecotestvip/ and I ordered radiation detector for home use too. We should do all possible to protect our home and environment.
I think it gets presented incorrectly. The Earth will recover from whatever we do to it, but humanity won't. People are quite selfish by and large, the focus needs to shift to what we lose if we don't recycle or change our habits.
Your average punter doesn't care about an animal in another part of the world, but they'll soon notice when we run low on resources and all the prices shoot up.
So we absolutely should care, I just think if we want to see a difference in behaviour, we need to change the focus.
