Soil isn't just dirt-it's what gives your food nutrients. It's the basis of entire ecosystems. It even stores climate-changing carbon safely underground.But soil is at risk.Food today is about 40% less nutrient-dense than it was 50 years ago. The takeaway: Poor soil grows poor-quality food.Soil is also disappearing. By 2050, 90% of the earth's topsoil will be gone. That's one soccer field of precious earth lost every five seconds.At this rate, farmlands have fewer than 60 harvests left.
