Oxygen in Greenery

I've often seen people energetically running, walking and working out in the park in the evening. It struck me though that mornings and nights are the only time that green stuff actually emits tons of oxygen. In the early evenings they are usually full of carbon dioxide! (Perhaps it's like training in high altitude - less oxygen so more endurance.:)

I wonder if people think of that or if they just like to see all that pleasant green around and assume they're breathing in richer air?
