Answer:
It's been over 20 years since the Montreal protocol was brought into force. The treaty, which aimed to control substances which lead to the depletion of levels of ozone in the earth's stratosphere, has been hailed as a great success.
The ozone layer is vital for the continuation of much of life on earth - its protective effect stops harmful UV-C radiation from reaching the surface. Whilst some of our efforts may have had unintended consequences , the struggle still remains to ensure that the existing hole does not continue to grow.
The data below shows that since the Montreal protocol came into force, the size of the ozone hole has increased in size by 36%. The hole was around the size of Cuba in 1979 (130,000 sq km) and has grown to the size of North America today (25 million sq km).
