I haven't read all the comments. I just want to add few more thoughts to my previous post.
My concern is not about whether you eat meat or fish but what kind of meat and fish you eat and what kind of vegetables etc.I eat.
Eating meat that is full of hormones and other chemicals that should not be there in the first place is unnecessary. It only makes those chemical companies richer at the expense of your health. You don't care and don't want to support the production of organic meat because it is too expensive or for other reasons? Fine, it's your stomach that has to deal with that crap after all not mine!
Eating fish that is caught with unsustainable fishing practices is irresponsible. The fish eaters cannot keep ignoring the fact that fishing stocks around the world are exploited to the point of no recovery! Do you want to make a difference? As Sambolino44 mentioned earlier eat fish that is not in such a danger of being totally wiped out, buy local species instead of ones that have imported from the other side of the globe, and when eating in a restaurant ask where the fish comes from etc...
Avoiding eating fish that is full of hormones and other chemicals is a tough one if the fish is caught in the wild, if it is a farmed fish then find out as much info as possible about the farming practices. I have recently heard that farmed salmon is really bad because to make its flesh pink farmers add colorants to its diet...Do you really want to eat that?
The bigger the fish the more heavy metals and chemicals accumulate in its body. Where all that nasty stuff comes from? Industrial dumping, farmed fields and us through the sewer. People flush god knows what kind of chemical concoctions down the toilet, especially pharmaceutical drugs, every day! They think that they get rid of these unwanted chemicals once for all, but they do not realize that those chemicals end up in the ocean and accumulate inside the fish and marine mammals. if these people do not care about what kind of fish they eat they may end up accumulating in their own bodies the same chemicals that they wanted to get rid of in the first place!
Dumping this stuff into a storm water pipe or your toilet is not the answer!
Amen!
