Sixty years. That’s how long U.N. officials said we have until all the world’s topsoil degrades to the point that it’s no longer useful for farming (and this was back in 2014, so it’s more like 55 years now).
Massive farms—the kinds that lean on chemical pesticides, large tilling machines, and other growing techniques that strip the ground of nutrients—are one of the biggest threats to our soil. As the global population rises, more hungry mouths to feed will likely mean more of these environmentally damaging growing practices.
On the other end of the spectrum, you’ll find regenerative farming that actually mimics nature to restore soil health by pumping nutrients back into the ground. (You can learn more on how it works here.)
