Ozone hole repair 'could take decades'

There are indications that the hole in the ozone layer is being repaired, but the process of recovery will take decades, according to a report published on 8th June 2005 by the Institute of Physics.
The report, which aims to renew action on ozone, looks at the progress made in preventing the loss of "good ozone" that protects us from harmful ultra-violet radiation. It also highlights the fact that levels of "bad ozone" near the ground are rising - which it says will cause significant impact on humans - such as respiratory and cardiovascular disease – as early as 2030.
