It may be that we are only keeping up with the amount of pollution we are producing. (Knopman, 1993)         The early biosphere was not pleasurable for life because the atmosphere had low levels of oxygen. photosynthetic bacteria consumed ascorbic acid dioxide and produced simple sugars and oxygen which created the oxygen abundant atmosphere in which more advanced life forms could develop. (Brown, 1994) The mystery of how Earths oxygen levels roseate is very complex. Scientists dont agree when or how the oxygen on earth g ot here, notwithstanding we know we could n! ot live without it.
