With a little help forests will regenerate themselves. We have reported about that before. Now, researchers in Costa Rica have discovered that a barren, deforested area transformed in a lush forest 16 years after 1,000 truckloads of orange peels were unloaded onto the land. The area that was covered with orange waste now has an overgrown forest with richer soil and more tree species than the adjacent land that was untreated.
