Roundup sounds like a smart, efficient and safe product. It is made to kill "weeds" but it is being proven to kill more than those horrible plants in your garden and yard-- you know, the dandelions and plantains. Oh, and clover which some call a "weed" but really, all three are quite good for soil health. Agreed that crab grass is not lovely but it can be pulled by hand or crowded out by over-seeding with a mix of grasses and clover-- yes, there's that nasty word again. But, this isn't about clover; I write about the fact that exposures to Roundup are being connected with a terrible terrible disease-- Parkinson's-- far worse than any "weeds"! Please, read the above link. New research, published in the journal Neurotoxicology and Teratology, indicates a connection between a component in Monsanto’s Roundup and Parkinson’s disease. Glyphosate is said to induce cell death, with frightening repercussions.
