honestly this is something that if if was written by a human and had a very good science article around it, I could still care less. It certainly might have an effect but its not going to be impacting the way the rest of global warming is or the worse effect of pollution in general and species die off. One thing that got me the other day is we are living in an age where you are warned not to eat to much fish because of mercury content and you have to be careful about the grains you eat do to pesticide usage.
