Paris wants to build a massive forest that would be 5 times larger than Central Park

For over 15 years, the city of Paris has planned to plant a new forest on the plain at Pierrelaye-Bessancourt, an outer suburb. But the plan has faced roadblocks as people debate the best use for the land.

French politicians are now actively pushing to make the re-greening project a reality.

The SMAPP plan calls for 5.2 square miles of trees and plants. For perspective, that's about five times the size of New York City's Central Park.
