Scientists at MIT and other locations have been eyeing the hole in the ozone layer since it came to the forefront in the '80s.
The fear when the hole in the ozone layer was first discovered was that it might lead to harm for humans around the world since we need the ozone layer to protect us from all sorts of deadly things that come from space.
The good news is that scientists have announced that the ozone layer hole has shrunk significantly since 2000.
According to the team of scientists, the ozone hole has shrunk by more than 4 million square kilometers since 2000.
To put 4 million square kilometers in perspective a bit, that it about how large half the area of the contiguous US is.
Scientists have also noted that the healing of the ozone layer hole has also slowed for the first time and the finger is pointed at volcanic eruptions.
