Longer Step: Ideas for Justice and Sustainability

  Mercury in tuna: Got interested in this last week, and did some research (I'm not a trained nutritionist; do your own research). Here is an interesting piece in Consumer Reports, which I summarize here, with some other reading results: ***Eating too much mercury can wreck your nervous system and damage your brain. Some tuna have dangerously high mercury levels. But low-mercury tuna has very healthy fats in it, and should be eaten (unless you're vegetarian). 1.

The only way to view this is to admit that most of us just don't care if we kill or maim others, if we help create worse new Covid variants, or if we get sick ourselves. Are we that selfish and uncaring, even about our own health?
