Industrial agriculture exhausts the natural resources on which we all depend. It makes us sick and undermines the world's capacity to feed itself. It is the very definition of unsustainable.
This model of farming has persisted for more than 60 years, since WWII chemical companies like Monsanto needed a market for wartime inventions and pesticides were put to work in U.S. fields. In the decades that followed, an entire model of agriculture has taken root — one dependent on ever more (and ever more expensive) chemical inputs.
