The US is #61, close with Venezuela, Paraguay, and Georgia. Sigh. We really can do better than this. The study was done by Yale and Columbia.
Though scoring highly in forest sustainability and provision of safe drinking water, [the US score] is offset by high greenhouse gas emissions and local air pollution issues.
It really is sad that the US (a major power in the world) has been unwilling to change. Someday people will wake up and realize that nature is not invincible, that people need to start living more in harmony with the natural world.
