My son asked me a question the other day I had no answer for: If we could not survive without plant life breathing out oxygen for us then why don't we have a harder time breathing in the fall and winter when all the leaves/plants are generally dead? You would think that would create a larger content of carbon dioxide in the air causing poorer air quality. Yet somehow, as a runner, I always seem to breathe better when outdoors in the winter months.
