Greenhouse effect/ozone depletion questions...?

Ozone depletion effects the biosphere by trapping the gases released by the release of bovine methane gas. This is similar to the greenhouse effect, but that is caused by the release of fossil fuels. So these are related because they are both caused by the release of gases. The difference is that greenhouse effect is caused by fossil fuels and ozone depletion is caused by bovine methane.
