Let’s put any amount of contaminates in our drinking water just so people can “filter them out.”
Someone mentioned arsenic earlier in this thread, and I think I can find some study that says arsenic is good for you. Let’s add it to our water and anyone who thinks it’s harmful can just filter it out.
Also, I’m adding my fecal matter to the water supply to improve people’s microbiomes. They can just filter it out if they don’t like it.
