Fish Kills Linked to Water Pollutants

I love eating fish. I think most of Japanese people like it, too. I felt sad to read this article. In the US, fish killed by water pollution.

About 50 years ago, there was a disease called "Minamata disease" in Japan. It caused by water pollution. The reason was industrial waste water from factories nearby the river. At first, fish were polluted, then people eat them without knowing that they were contaminated. After that, people became sick because of the fish.

I think water pollution returns to us. We have to think about the environment when we catch fish.
