While it is true that the depletion of the ozone layer occurs by a mechanism that is completely different from that which causes the greenhouse effect, it is easy to conflate the two. To wit:

Ozone is itself a "greenhouse gas" and contributes to the greenhouse effect.

The mechanism by which ozone is depleted relies not only on "ozone depleting chemicals" but also on temperature and light: it occurs in the southern hemisphere in the early spring, when it's very cold but the sun has just come out. So, a change in temperature may provoke a change in the ozone layer.

It's all connected, man; it's all connected.

The trouble with peak oil is that it will be replaced by dirty coal. Not only will we still have billions of tons of CO2 spewing into the atmosphere, but we'll have thousands of additional tons of mercury, uranium, arsenic, sooty ash, and many other heavy metals and carcinogens.
