Save Soil

Soil degradation is a global phenomenon. 40% of the soil is already degraded. By 2050, about 87% of fertile soil will be degraded, and the population of our planet will be 9 billion by then. The result will be huge shortages of food, starvation, and migration. Worse still, bringing back its original level of fertility, takes around 15-20 years. The only way to avoid such a disaster is to save the soil. This book explains why soil degradation occurs and how to prevent it.
