Students in the Philippines might soon be required to plant 10 trees before they can graduate. A proposed law in the Southeast Asian country could lead to 175 million trees being planted in a year.
The law addresses the problem of deforestation. Over centuries, people have cut down 75 percent of the country’s forests.
Trees absorb carbon dioxide, a gas that causes Earth to warm up. “The more trees we plant, the better,” says Alice Van der Elstraeten, who fights deforestation for the United Nations.
