Apple is planting a forest in Cupertino, California. When the company’s new headquarters is completed later this year, 8,000 trees, transplanted from nurseries around the state of California, will surround the donut-shaped building by Foster + Partners. The trees are meant to beautify Apple’s 176 acres (dubbed Apple Park). But they will also absorb atmospheric carbon.
That’s a good thing. Carbon, in greenhouse gases, is a major cause of global warming. Almost everything humans do, including breathing, releases carbon into the atmosphere. Plants, on the other hand, absorb carbon, turning it into foliage, branches, and roots—a process known as sequestration.
