Carl Freeman, a Wayne State University biology professor, commented about the Ontario government's decision to level charges against Royal Polymers, the company that dumped cancer-causing chemicals into the St. Clair River during last year's power blackout. Freeman said Canada's crackdown on the company shows that the spill was more than just a minor incident. \"That stuff is incredibly dangerous. And, of course, it\'s to industry\'s advantage to tell everyone that they have nothing to fear,\" Freeman said.
