A new type of genetically engineered fish is allowing those working in conservation careers to see the effects of pollution on fish.  A black and white zebra fish shows up green in the parts that are hit the hardest by pollution.  The areas where there is a lot of green are the areas where pollution affects them the worst.  So far, the reproductive system seems to be the worst areas.  This can cause a problem for future generations. 

"This is a very exciting development in the international effort to understand the impact of estrogenic chemicals on the environment and human health," co-author Charles Tyler says in a press release. "This zebrafish gives us a more comprehensive view than ever before of the potential effects of these hormone-disrupting chemicals on the body."
