GMOs are often genetically created artificially to tolerate herbicides, made by Monsanto and others, that kill weeds. The herbicides contain glyphosates. Monsanto's Roundup weed killer is meant for Roundup Ready GMO crop seeds. It's an extremely toxic glyphosate agent.

Glyphosates greatly harm grazing animals and pollute the wells and groundwater of farm areas where they're used. (http://naturalsociety.com)

They create sterility and birth defects among animals and humans. Most of the honey bee die-off, or colony collapse, is attributed to glyphosates. If enough pollinating bees disappear, our food chain is endangered further.

Glophosate's chelating capabilities remove minerals from the soil where they're sprayed. So crops get increasingly worse while increasingly abundant Roundup resistant weeds, or super weeds, force farmers to add more toxic materials to Roundup.

It's a vicious cycle for farmers who, conned by greater production promises, unwittingly signed on to Monsanto Roundup Ready GMO binding seed contracts. Monsanto uses patent laws to litigate against farmers whose non-GMO fields are contaminated by GMO fields, forcing smaller farms out of business.

Most farmers fold because they cannot afford the litigation. American farmers are attempting to organize against mostly Monsanto's GMOs. European farmers have managed to resist thus far.

Why you should be concerned
Maybe the reasons summarized above are too abstract. So let's get personal. Contrary to mainstream media's (MSM) outlook, the jury is not out on GMOs. GMOs do destroy human and animal health while endangering non-GMO crops with contamination. That's been discovered by several scientists acting independently.

They jeopardize their careers and even their lives by communicating what they find while the MSM ignores them. Anti-GMO activist and author Jeffrey Smith lists the casualties and summarizes Monsanto's harassment here:
