The ozone layer is a thin layer of the Earth's atmosphere that absorbs the sun's ultraviolet rays. When there is a hole in the ozone, these rays are able to hit Earth.
Essentially, the ozone layer blocks the harmful ultraviolet radiation from affecting humans or other living creatures on the planet.
It is believed that the progress in the size of the hole is the result of the ban on ozone-depleting chemicals, known as The Montreal Protocol.
