When Hurricane Maria roared through Puerto Rico last October, it did more than rip off roofs, destroy the power grid and kill people. It also tore up the forests that cover over half of the island. Many trees were stripped of foliage and branches; others simply blown out of the ground or snapped in half. Lush landscapes were instantly converted to expanses of naked trunks; normally cool, shady forest floors were baked by the sun. In days after, the chatter of frogs stilled, dead birds littered the ground, and bees buzzed around crazily, looking in vain for flowers.
