Frank is right. Any community college environmental biology class teaches that it is fertiliser run off that causes the massive dead zone in the Gulf of Mexico. And by the way...anything you use on your lawn or plants is a chemical. There is no such thing as a non-chemical fertiliser or pesticide. Even if it's vinegar. It's not so much the glyphosate that is harmful...it's the inert ingredients, one of which is a suspected carcinogen. The thing is...is that the public can't buy straight glyphosate. We can't even buy it's big brother, Rodeo, which is safe for use near water.

Those dead zones are the result of pollution due to fertilizer run off. Phosphorus which is a nutrient in all fertilizers, moves readily through the soil and into our storm water sewers where it eventually ends up in our waterways and here in the Midwest, the Mississippi river watershed. Phosphorus causes huge algae blooms which as it grows and then decomposes, absorbs oxygen in the water which kills not only fish but all other macroinvertabrae. Glyphosate is not a nutrient. I'm not going to get in a debate over organic versus natural remedies for controlling weeds as if one can control weeds in their own yard without the use of chemicals, I say go for it but herbicides are an important tool in restoring habitats and ecosystems on a vast scale ( several acres ) besides the fact they're more efficient, cost effective and the means justifies the end result. Frank We abuse the land because we regard it as a commodity belonging to us. When we see land as a community to which we belong, we may begin to use it with love and respect.
