Dozens of trees around the one that was struck are electrocuted. Within months, a sizable circle of forest can …

In return, the fungi receive carbon to grow their networks. In this way, 13 billion tons of atmospheric carbon dioxide — one-third of fossil-fuel emissions worldwide — enter the soil each year. These fungi cannot live on …
