NASA has been improving life on Earth for while too . Back in the 1980s , NASA research led to the discovery of the ozone hole in the atmosphere , which imperiled life on Earth .

We ran to the United Nations . As a result , they signed the Montreal protocol , the treaty that banned those chemicals .. that would have been the end of the world as we know it .

Despite our technological advances , limitations still exist for humans attempting
