The fact that we can't eat fish normally is something that all Americans should be mad as hell about. CEOs of chemical plants and their families should be forced to live within 1 mile of one of their plants. Things would get cleaned up right away.
I have a friend who loved sushi and she ate it at least once a week, if not more. Her daughter was born in the bottom 1% of size, so they took a blood test and her blood was poisoned with mercury from how much fish she consumed. She went through months of chelation therapy to bring it down, but the fact that she had to go through that is a testament to how fucked up our water is and how much we are killing the environment and ourselves.
Everyone should do this, honestly. I am currently renting, but I previously owned a home in another state. One of the first things I did after buying my previous house was a whole-home filtration system. The cost isn't that high if you already have a water softener or similar plumbed in off the mains, as the filter system itself isn't the expensive part, it's the plumbing work.
Even in cities with good water, it makes sense to filter heavily and remineralize at home. This ended up helping me in myriads of ways due to natural disasters causing boil orders, finding out about chemical spills in the area that affected water supplies, etc. No worries at my home, thanks to significant filtration.
