Two Brothers, Two Buckets, and World Hunger:
Teenagers Grant and Max Buster are proposing a solution to world hunger that anyone can do. All you need are 2 buckets, a few square meters of ground or rooftop, sunlight, and a some water. Distraught by the hunger in the world, the Buster brothers spent their summer vacation designing this simple garden in a bucket. They placed two five gallon (20 liter) buckets set inside one another, to which they added some soil, water, bits of plastic pipe. and some strategically placed holes. Turns out this simple system for food growing can reduce water usage between 50 and 80 percent, with a 100 percent reduction in weeds (and hence herbicides)! And they figure you can use it anywhere, from rooftops to industrial wastelands. With a bountiful rooftop garden, the brothers are now researching even more efficient and low-impact gardening systems that don’t require the buckets, which are considered very valuable in some remote communities of developing countries.
