Who killed this land?

Agriculture is the foundation of social development. Land is the lifeline of agriculture and the foundation of human survival. However, if it is not used properly, the land will become "sick" or even "die". China's per capita arable land area is 1.59 mu, less than half of the world's per capita. Protecting the land is particularly important.

Today is the 34th National Land Day. Let's take a look at what happened to these sick lands and how to properly protect our lands!
