two worries led to one

the thing that worries me most is the drought. Not many things worry me about the world, I'm almost selfish in that aspect. But nevertheless the drought does actually worry me. After this assignment was assigned my professor told me what he thought it was going to be like in the next 50 years, and it sounded mostly good but the big questions were will there enough food? Will there be enough energy? Will there be enough water? Water being the most important of course, last but by no means least. This was said to me today, a Wednesday. I already felt some type of way about water before but now it's a legitimate worry for our future. I can see how it's scarce, I can see the world over populating. I can literally see pollution down the street. Our water sources will go dry one day. Another thing too that it's going to suck I believe that when I get older water bills are going to be jacked out the wazoo and I'm to have to pay for that damn thing. I cant really imagine what they could do the help the situation which is the biggest thing that worries me. But I believe by the time the worst case scenario will happen I will most towards the end of my life, and that worst case scenario is literally no more water. Which brings me to the movie the Book of Eli. They called the end of the civilization the "big flash," and that showed the world as a dry desert. Which leads to my second worry, atomic wars. I feel that that world in the Book of Eli was destroyed by nuclear war which caused the civilization to end and made all the water to decimate. With that being said it leads me to think man can take away and screw things up so much quicker than mother nature would. If it wasn't for humans this planet would last for billions of years, and unfortunately I doubt that. My astronomy spoke of what he thought the world would be like 5,000 years from now, he said there would probably be no more people, just robots, smart, like people. Then to think that was all created by people, humans. If anything, explaining this causes me to think I'm worried about the people of this world in the future. I can't imagine the world making it 5,000 years from now, and that scares me some how.
