Monsanto has agreed that glyphosate-based products are neither "biodegradable" nor "environmentally friendly" and has discontinued using these terms in advertising -- at least in New York State.
Glyphosate is the most commonly reported cause of pesticide illness among landscape maintenance workers in California, and the third most commonly-reported cause of pesticide illness among agricultural workers in California. A few more facts:

- Glyphosate is suspected of causing genetic damage.
- Glyphosate is acutely toxic to fish and birds and can kill beneficial insects and soil organisms that maintain ecological balance.
