> But it's not known if that poses health risk This is the big question. I think people around the world have been ingesting microplastic for 30 years or longer, yet there's no reported case of any direct toxic effects. So I guess microplastic doesn't have immediately effects on health, but I won't be surprised if future studies find longterm effects, such as increasing the risk of cancer, damage to the circulatory system or the brain. Overall, I think we must take actions immediately for solutions, but I won't particularly worry about this problem and I'll continue buying bottled water. It's not unlike the air pollution in the 20th century, one has to live with it. Nevertheless, "microplastic is going to kill all of us" surely is going to be the trope of the next decade.
