Using the unused: Bottles to trees
Douglass Jacobs and Owen Burney have developed Bottles to Trees, a program to address the need for a nursery system that translates into reforestation in countries, such as Afghanistan and Haiti, where trees are desperately needed. With a few cuts and modifications, a discarded plastic soda bottle can work nearly as well as the best technology on the market to grow tree seedlings -- and far better than the one-time-use seedling bags prevalent in those countries. The result has the added benefit of repurposing plastic that would otherwise contribute to local litter accumulation.
