“When a tree falls in a forest,” Agassiz explained, “it decomposes, and—poof! All that carbon circulates again. When moss sinks in a bog, it doesn’t decompose. It just stays there, down in the dark, as long as it’s not disturbed. Go down home, Jenny Moss! The bogs are the firm’s most precious assets … our vaults. As fast as the storm computer kicks up carbon, we suck it back down, and we keep it here.” She slapped her tail on the moss.
