2nd guest speaker Mike

I thought this guest speaker spoke about a very interesting subject. I did not know that California's water was pretty much toxic. And also that there was a risk of eating too much fish. Its a good thing that I don't eat too much fish from California anyways. I also liked how he went more in depth into the different types of mining. It is sad to know that what happened in the past has made California's water tainted with mercury forever, or until the government or somebody finds an efficient way to get rid of it.
