gender bender

i love to fish for bass, and you can catch different types of them in any number of rivers and streams that flow in and around the chesapeake bay. i have been catching and releasing for the last couple of years as reports are released not only on the continued poor health of our waterways but also, the genetic mutations in the fish caused by this pollution. this week, the u.s. geological survey released the results of their nine-year study on fish from 111 different sites across the country: the results are very scary, with a huge percentage of male large and small mouth bass showing female characteristics. they say these morphed fish are not harmful to eat, but i will wait for the next study to verify that! lab experiments reveal "estrogenic compounds" derived from birth control pills, agricultural runoff loaded with pesticides, biodeisel fuel production, as well as an ingredient in plastic as the culprits. simple thought: reduce these chemicals in the waterways.
