Mother Earth: Peace and Harmony

Some time in the near future mother earth will cleanse herself in one way or another. Maybe a new ice age, melting of the ice caps, fresh water released into the oceans causing the gulf stream to fail and the Northern hemisphere cooling down. There could be a large volcanic eruption which could cause a nuclear winter by blocking out the sun. Earth quakes in the oceans causing tsumamis engulfing the land masses. Our life style in the past 200 years has helped to increase these events occurring. With the world population growing we have to feed each other and have a good supply of fresh water but this won't be the case in every country, so will man press the self destruct button by fighting over these resources? I cannot believe this will happen and I hope man will come to his senses and let peace and harmonies prevail.
