Earth - Rejuvenation of our planet/Greening the deserts

What if we could transform deserts into good usable land? What if we could make it fertile and abundant with delicious fruit and vegetables? What if we could raise the water table in the deserts and create natural springs through the landscape where nitrogen fixing tress will grow and birds will nest, where bees will come and spread pollen from flower to flower. This is part of the vision for Rejuvepedia. We want to be able to rejuvenate not only the bodies of the humans living on this planet but also the gardens in which they live.
