Last week, Hurricane Maria made landfall in Puerto Rico with winds of 155 miles an hour, leaving the United States commonwealth on the brink of a humanitarian crisis. The storm left 80 percent of crop value destroyed, 60 percent of the island without water and almost the entire island without power, as seen in the nighttime satellite images below.
