Tiny Creatures That Protect Rice Fields

These tiny creatures are are one of the most important on earth — and chances are, you’ve eaten them before. You see, farmers first buy them in huge numbers from local markets, then they release them into their rice fields. As they grow, they feed on harmful insects and pests, keeping the rice healthy without the need for chemicals. While crawling through the mud, they also aerate the soil and help improve water quality. Months later, once the crabs are fully grown, they’re collected and sold back to the market — and end up being eaten with the very rice they once protected.
