Green Fish Can Help Prevent Infertility?

This article caught my attention.  It's been widely publicized that infertility is on the rise around the world and that male sperm counts have been dropping dramatically over the past 50 years.  One theory is that estrogen, which can be found in water, soil or even food can contribute to male infertility.  So a team of researchers in China have genetically modified a fish so that when it swims in lakes and rivers polluted with estrogen, it turns green.  Environmental officials can then treat the water to remove the problem.  More details....

Widely found in water, soil and even food, environmental estrogen poses a great threat to the reproductive abilities of humans and animals, researchers said, noting even a tiny level of estrogen can leave men infertile.
