Gravity depletion !

I have been reading so much about global warming and the ozone layer depletion etc and what it is doing to our environment. Suddenly a thought came to me as to what would happen if Gravity depletion happened. Isn't it a wierd and scary thought, depending on how much it depleted, it would be fun or outright disaster. if it just deplted a wee bit, we would all weigh a little less and feel light weighted and consequently probably light hearted :-). If it depleted a little more we can all jump around to great heights and fences would become useless. If it depleted a little little more then we could all fly say at 5 or 10 ft, our cars could also fly and we would not be caught in traffic jams anymore and we would not need roads either. let me post this more about it in the next post.
