Arvay argues convincingly for the importance of trees in human nature. We evolved from forest-dwelling mammals, after all, and a verdant canopy of leaves is sown deeply into our genetic memory. He cites several clinical studies suggesting strong links between the presence of trees and human health.
"Our immune system is not strengthened by substances from trees," he asserts, "but it is rather weakened by the separation from these substances in modern life. Spending time in nature therefore does not lead to more defense cells; rather it brings their number and activity back to a natural level."
Separation from nature is as much a destroyer as any environmental toxin.
