Save the Soil, Save the World

摘要

DESPITE ITS HUMBLE position, the planet's thin layer of arable topsoil is essential to life. It's both incredibly important and complex, two themes explored in Kiss the Ground, a recent documentary about regenerative agriculture from directors Rebecca Harrell Tickell and Josh Tickell. The main point, delivered with charm and a calm folksiness by Woody Harrelson, is simple: Soil is alive. Every handful of healthy dirt contains more microorganisms than there are humans on the planet. Importantly, all these magical little critters are hard at work around the clock, exchanging water and nutrients, breaking down organic matter, feeding plants, and sequestering carbon.
