While reading BBC News I found an article about the ozone hole and how a scientist says that we need to pick up the pace on protecting the ozone hole. Joe Farman the scientist who discovered the ozone hole over Antarctica says that we need to pick up the pace for protecting the ozone layer of the Earths atmosphere. The ozone layer blocks ultraviolet-B radiation from the Sun, which can cause skin cancers and other medical conditions, as well as harming wildlife. Many countries are starting to switch there chemicals, refrigeration, aerosol, and fire fighting to better ways for the atmosphere, and the countries that have just started switching say they will be done around 2010. One of he chemicals that humans have stared using to protect the ozone hole is called hydrochlorofluorocarbons (HCFCs). There are many different types of HCHCs being used to help protect the ozone layer. Joe farman believes if we start using ways to help protecting the ozone layer and the hole then it should be fixed in about 10 years.
What else can we do to protect the ozone layer? How did Joe Farman discover the ozone hole in 1985?
