Will earths oxygen ever become impaired and a threat to human civilization?

Asked by john65pennington (29258points) January 13th, 2011

Will it ever come to the point, when earth’s oxygen will not sustain human or animal life? Will you or I even be around to know the answer to this question? Will this happen in our lifetime?
