because if thats the case
consider this
we talk about the ice caps getting smaller then they were 100 years ago
due to global warming
now think about it for a while
most the human body is made up of water
the average humans weigh around 60=kilo`s so up to 40 litre
off water
now if we say that the population increased by 1 billion in a 100 years == 40 billion litre off water missing in action
second to that how much water is sitting around in shops as bottled water /soft drinks/ beer /hard liquor and in rain water tanks farmers dams in short taken out of the normal flow back to the oceans leaving less to turn back into ice ???? i am sure the smart people on this site will correct me on some off my points but it would not be totally wrong
