Lack of oxygen has not been observed as a product of world-wide forest
conversion to younger forests, agriculture, other vegetation, or
urbanization. However, these conversions do figure in the C cycle, as
most forests store much more carbon as primary forests, than as younger
forests under intensive silviculture. As far as the worldwide O2 cycle
goes, the ocean's phytoplankton play a large role--- we should worry about
how ozone thinning affects it, instead of dithering about sunscreen.

This is quite true. These forested areas are a result of overgrazing and
fire suppression. They are also inherently unstable, as frequent drought
stresses the trees, making them susceptible to bark beetles and
defoliators. When fires do occur, they tend to burn intensively.
Grassland, with occasional trees, was the pre-settlement condition.
