Soooo, every promise you made was a sham?-----Antarctic Ozone Hole Remains at the Same Size as North America

Antarctic Ozone Hole Remains at the Same Size as North America | General News:
"Scientists previously expected to reduce in size quickly when the use of ozone-depleting chlorofluorocarbons (CFCs) substances were banned 27 years ago, but it remains the same level as it is in 2010 to 2013.
....Scientists remain uncertain why the hole has not reduced more since the Montreal Protocol agreement was signed by countries in 1987.
This global treaty bans the use of CFCs substances that were widely-used in household and industrial products such as refrigerators, spray cans, insulation foam and fire suppressants.
...They said had the Montreal Protocol not sign, the atmospheric levels of ozone depleting substances could have increased tenfold by 2050."
