As a prepper, I’ve been getting more into permaculture and how it can reverse desertification. A healthy “food forest” is useful in situations where food cannot be found at the grocery store. Healthy land produces better gardens and orchards, and permaculture encourages healthy land.
Much of the world has experienced expanding deserts while losing grasslands and forests. The Great Basin has experienced desertification on a massive scale over thousands of years. The Great Basin contained one of the largest freshwater lakes in the world, surrounded by forests filled with wildlife. Lake Bonneville, as the lake is called, was bigger than many modern countries. Now all that remains is the Great Salt Lake, salt flats, deserts, and some forested mountains.
