The world's population must work together in order to get
the climate to gain it's stability, because it is man who has
caused the imbalance that leads to global warming. Pollution and over-population is only getting worse. Look at the statistics and you can see the evidence. If the ozone hole were
to get too much larger, then the dangerous UV and gamma rays would cause a possible melting of the glaciers in the north and south poles, resulting in a major change in climate. Then the earth would not sustain life much longer.
