Usually, when you buy something, you pay for it just once. But if you’re a US taxpayer, you’re paying twice for the food system you’re “buying” with your hard-earned tax dollars. An example: today’s massive federal farm subsidies encourage farming practices that lead to toxic algae blooms, drinking water pollution, and other costly problems we have to pay for again downstream. By contrast, modest investment in just one proven alternative farming system would achieve annual savings—in the form of water pollution averted—of $850 million.
