IIRC, during the Carboniferous period, insects were able to reach such huge
size (such as the infamous dragonflies with wingspans of nearly 3 feet)
becasue the percentage of oxygen in the air was very high - at that ime,
there were also supposedly more fires due to the resulting ease of combusion
(e.g. from lightening), although I don't recall whetehr that last point was
based on evidence or theory. One thing I don't recall ever reading or
hearing concerns ozone - lower-level ozone is considered a pollutant, because
it irritates human and animal respiratory membranes, but upper-level ozone
shields the earth from much UV radiation/light. One would assume that a
higher oxygen level should lead to a higher ozone level, but I don't know
whether that assumuption is correct (still looking).
