hey people

 

i remember back in high school some fellow was telling my year that we should use roll-on deodorant instead of spray cans, he said because they damage the ozone layer. However i read that in the US Chlorofluorocarbon was banned in like 1970's which was the substance that damages the ozone, and only old devices still produce it ei old fridges. I live in Australia , but i am guessing its also banned here aswell. So was that guy uninformed or is there other stuff that damages the ozone which is contained in sparay on deodorant cans?

Since the Montreal Protocol came into force in 1989 CFCs have been replaced, in nearly every country, with mixtures of volatile hydrocarbons, typically propane, n-butane and isobutane. Australia, being a civilized and responsible country I would assume they adhere to the new standard.

CFC's are banned, however the mixture of hydrocarbons in the aerosol still doesn't do the environment much good, it just the lesser (far lesser) of 2 evils.
