When I went fishing with my father as a child, we could eat the fish we caught in the lake. We didn't have to worry about the water in the lake having chemicals & bacteria, etc in it. The fish we caught in the lakes were O.K. to eat until I reached my teenage years, although today I would not eat any fish I caught in the lakes where my Dad and I use to fish. Most lakes are full of bacteria & chemicals, people dump trash in the lakes, on the side of the roads, instead of putting their trash in garbage cans. It's very sad to think with all today's knowledge, things have gotten worse, instead of better. Man has polluted the earth, by throwing things into the lakes, which should be thrown into a garbage container. In the good old days man was more respectful of the things around them. People need to wake up and take care of our earth.
