tropical forests produce a large percentage of the earth's supply of oxygen. continued destruction of these forests is likely to reduce the earth's oxygen supply to levels that will threaten the existence of all oxygen-dependent life on earth.

which of the following, if true, most seriously weakens the prediction above?
A) all of the oxygen produced by the earth's tropical forests is consumed by bacteria and animals living in those forests.
B) some of the oxygen produced by the earth's tropical forests escapes through the upper atmosphere without being consumed.
C) the oxygen produced by tropical forests is consumed by animals all over the earth.
D) the earth's tropical forests are being destroyed at a rate of hundreds of acres everyday.
E) tropical forests contain the most diverse selection of oxygen-dependent animals on earth.


what is the answer? please explain.
thank you.
