There’s a lot of former forestland in the country. What if we planted trees on it again?
The U.S. was once covered in around 1 billion acres of forest. While much of that land has been developed, a recent study led by the Nature Conservancy found that there are still as many as 127 million acres of former forestland in the lower 48 states—an area about twice the size of Oregon—that could feasibly be reforested. In that space, we could plant 68 billion trees, which could capture more than 300 million metric tons of carbon dioxide every year, roughly as much as the pollution from 67 million cars.
