“People slice up tree trunks, nail the pieces together into boxy shapes, and then go inside to sleep. Trees use the wood in their trunks for a different purpose—namely, they use it to fight with other plants. From dandelions to daffodils, from ferns to figs, from potatoes to pine trees—every plant growing on land is striving toward two prizes: light, which comes from above, and water, which comes from below. Any contest between two plants can be decided in one move, when the winner simultaneously reaches higher and digs deeper than the loser. Consider the tremendous advantage that wood confers to one of the contestants during such a battle: armed with a stiff-yet-flexible, strong-yet-light prop that separates—and connects—leaves and roots, trees have dominated the tournament for more than four hundred million years.”
