I do not support anything contributing to the massive epidemics of neurodegenerative diseases in our elderly (and not so elderly!) and neurological damage to our babies and children. We have unprecedented numbers of kids with neurological problems (including all the gender differences). We simply MUST have options to opt out from herbicides and pesticides.
You have one. Buy acreage, plant your own food and live as you wish.
You seem like a reasonable person and you have 4 wonderful children. You can buy organic and grow your own food. Those are two options. I have a toxicology background. Everything man made or natural has a toxic dose. The DOSE, is the key basic concept in all of toxicology. The dose diffentiates, the poison, the remedy, and the harmless in all cases.
I use some pesticides according to label, but I also grow most of my own food. Blessings on those children.
