These Seussian flora need their Lorax. The bulbous mature specimens’ trunks are frequently dry, unstable and on the verge of collapse, and fewer saplings are spouting. The trees, which can grow up to 100 feet tall, are an integral part of Africa’s spirit and landscape. Communities meet around baobabs and worship their ancestors at the trees’ roots. The leaves and fruit have sustained hunter-gatherers for centuries, with the oldest known tree predating Julius Caesar. Although scientists suspect climate change, further investigations are necessary to understand the degeneration — before the last baobab falls.
