Tree of life is dying: Africa's ancient baobab

Africa's ancient trees of life are being killed by climate change. Researches found that nine of the oldest 13 baobab trees and five of the six biggest ones have partially or completely died in the past 12 years. The baobab tree is revered in Africa. Medicinal compounds are extracted from its leaves, while the fruit -rich in vitamin C -- is used for nourishment and the seeds yield oil. Three trees that were older than 2,000 years have all died in the past decade.
