In a speach at Kansas University about 15 years ago James Lovelock
mentioned this, that the rainforest doesn't produce that much oxygen.
He pointed out that it does act to cool the Earth though, and has a
large effect on weather patterns. Without it, he cautioned, that the
Earth might have a difficult time maintaining our current temperatures
and weather conditions which would otherwise fluctuate wildly.
Of course he mainly believes that living things create the conditions
that suit them on the Earth - that in this way the earth exhibits
homeostasis. Damage enough living systems and the homeostasis will fail.
You might look at his book, The Ages of Gaia, for more information on this.
