You misread the article:
” The results contrast with those released by the Environmental Protection Agency in August 2010. That study found that a mixture of oil and Corexit isn’t more toxic than oil alone to both a species of shrimp and species of fish. However, several studies have found the mixture is more toxic than oil to the embryos of several fish species. The EPA could not immediately be reached for comment.
“To date, EPA has done nothing but congratulate itself on how Corexit was used and avow they would do it the same way again,” MacDonald said.”
I think instead of science and reason, we have a gaggle of fools leading us in circles down the drain.
