Bye Bye Himalayas

What if the Himalayan ice glaciers melted? Currently the glaciers form rivers that run through all of Europe and Asia. These rivers are responsible for roughly half of the humanity's water supply. They also house several villages and many people. If they melted, the world as we know it would come to an end. Millions if not billions would permanantly lose water. Obviously a complete loss of water would cause dehydration and death. It would not wipe out half the world, but it would cause overpopulation to the extreme. China would lose a sever portion of its water supply and the already vastly overpopulated county would have to relocate many of its citizens. The one billion there may dwindle to as little as five hundred million or less. Where would the rest go?
If the glaciers melted and got rid of half of humanity's water supply, wouldn't a vast abundance of food disappear too? It's almost safe to say the half of the food supply could disappear. Farmers in areas by the Himalayas or even those that use the rivers the Himalayas create would be completely ruined. The farms would dry up and the crops would die, and they would have no way of feeding farm animals anymore either. (213) There would be no way to feed these starving individuals. They would have to move or die. If all of them moved, then other countries would begin to overpopulate, and possibly close their borders to immigrants. The United States is already struggling to raise corn and other farm grown products, imagine if three hundred million more people moved here? It is very possible that if the glaciers melted, the Earth's population could decrease by about two billion people. That would be very tragic. A solution would be to go green. This can be done several ways. People could use less gas, litter less, and prevent polution. If people can be a little more conscious about little things like litter and gas, things like melting glaciers wouldn't even be a topic of discussion.
