China has less than 10% of the world's arable land, yet it feeds nearly 20% of the population, and its grain production continues to break records year after year.
But on the same land, other things are happening. Northeast, South, and Northwest—three regions, three completely different problems.
The land is deteriorating, but grain production is increasing—these two things are happening simultaneously.
Many people blame chemical fertilizers. This answer is probably less than half right.
Ninety years ago, Americans planted 190 million trees to conserve their soil.
Ninety years later, China's answer is a layer of grass.
Today, let's talk about what's wrong with China's soil.
