The small ozone layer on top of the stratosphere is crucial for human survival. Why?

It is estimated that the total amount of oxygen (O2) contained in BIFs is equivalent to 6.6% of the oxygen present in the modern atmosphere. This is quite impressive given that the atmosphere during Archaean and early Proterozoic times was largely devoid of oxygen! Therefore, this reflects the photosynthetic efficiency of the early biosphere, coupled with its operation over long periods of time. Knowing that the mass of the modern atmosphere is 5.01×1018 kg, of which 21% is oxygen, what is the mass (in kilograms) of oxygen contained within BIFs? Answer x 1016 kg of O2 contained in BIF deposits Knowing that the molecular mass of O2 is 32 g/mole (0.032 kg/mole), how many moles of O2 are contained within BIFs? Answer x 1018 moles of O2 contained in BIF deposits Not sure what the "answers" are?
