Power of cork key to climate change fight, scientists say

One of the planet's most natural defenses against climate change and a key element in sustainable products is found in wine bottles around the world. Scientists and engineers say cork has been used to make several products in everyday life, from flooring to insulation, and the process of harvesting it leaves a small carbon footprint. "The tree tells us if we can take or not; you cannot force the cork to come apart," Conceição Santos Silva, a forest engineer, told ABC News last summer while the farmers were working on the trees.
