Black Plague and N1H1

What if the recent outbreak of the N1H1 virus had been as serious as the Black Plague that tore apart Europe in the 15th century? The Black Plague wiped out two-thirds of Europe's population at that time. If that happened today in the areas affected by N1H1, that would cover half of the world! Half of the world's population is around three billion people. Two-thirds of three billion people is two billions people. With two billion less people gone in the world, entire countries would be seemingly empty, with a few stragglers here and there.
This would obviously be a terrible catastrophe, but it would also open up a world of possibilities when the disease got cured. First, people could move to the empty countries and start life anew. A lot of workplace positions would open up, due to all of the people that died. A lot of resources would become more readily available also because a lot less gas would be consumed daily along with much less water and natural gas. However there is also a very negative side to all of the deaths. For example families would be devastated, lives would be ruined, and many businesses and shops woul have to be reestablished. All in all I would say this would be a very devastating catastrophe.

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.
