The Winds of Adversity
In 1987, 50 miles north of Tucson, Arizona, the Biosphere 2 was launched, an effort to study an enclosed artificial ecosystem. Every ecosystem needs trees, and trees grow rapidly in this protected environment. Everything seemed to be going great until one day some trees started falling over for no apparent reason. Jonathan Haidt in The Anxious Generation explains, “The designers had not realized that young trees need wind to grow properly. When the wind blows, it bends the tree, which tugs at the roots on the windward side and compresses the wood on the other side. In response, the root system expands to provide a firmer anchor where it is needed, and the compressed wood cells change their structure to become stronger and firmer.” (p.72)
