Save The Frogs Day is today!

I shamelessly stole this from Rambling Woods' Save the Frogs Day post and I hope she doesn't mind. This is really important to everyone in the human race.

This is toward the end of the short article, but it should be the first thing you read, "Over half of the DNA found in frogs is also found in humans, so if these pesticides kill frogs, imagine what they do to us!"

Pesticides and herbicides are toxic chemicals that generally undergo little to no testing on amphibians prior to their being approved for use. Unfortunately, the law of gravity has it that many of these pesticides end up in waterways, where amphibians live and breed. To make matters worse, amphibians have permeable skin that is highly absorbent. Populations of the endangered mountain yellow-legged frog Rana muscosa that live downwind of highly agricultural areas in California’s Central Valley have disappeared at a significantly higher rate than other populations.

Atrazine, perhaps the most commonly used herbicide on the planet (33 million kg are applied each year in the US alone), can cause hermaphroditism in frogs (males grow female sex organs) at ecologically relevant doses, and can reduce survivorship in salamanders. Atrazine also affects water quality in lakes, resulting in more snails. These snails serve as intermediary hosts of a trematode parasite that burrows into the developing limbs of tadpoles and causes limb malformations.

Roundup (also sold as Touchdown Total) is lethal to gray treefrog and leopard frog tadpoles, and most likely a host of other as yet untested frog species. Roundup is the 2nd most commonly applied herbicide in the USA; it’s produced by Monsanto, the same folks who gave us Agent Orange. Over half of the DNA found in frogs is also found in humans, so if these pesticides kill frogs, imagine what they do to us! Read more about pesticides here, and sign this petition to get Atrazine federally banned and out of production.

AWESOME post Caron. It is good for this information to be spread as so many do not realize the negative power of some of the chemicals "we" use on a daily basis!
