Ozone

Discussing about ozones with my family and friends reveals two types of responses: 1) I don't know or 2) oh yeah, i remember something about a hole over Antarctica.

People nowadays have not being notified too much about the ozone layer. Is it because we have banned cfc from refrigerants? The fact is that since the peak in 2000, the ozone hole has not decreased by much. Maybe because there are so many other news in the world such as climate change, wars, financial collapse, kim kardashian, etc that we lost interest.

Older generation can still remember the alarming news in the 1980s but has since forgotten about it.
