Water

There are many issues facing us as Americans, and many issues facing us as a world as a whole. But none seem to compare to the looming threat of water. Most people have no clue that there used to be a massive aquifer under Texas all the way up to South Dakota that no longer exists, and has created massive land subsidence all along where the water no longer is (that means peoples homes, roads and buildings are sinking into the ground in "random" areas.) Most people have no idea that 1.2billion people have no access to fresh, clean drinking water, or that the quality of water has been decreasing exponentially over the past hundred years. People hear "Global Warming" and think that it has only something to do with CO2 being injected into the air from our cars, but they don't seem to realize the massive droughts all across the globe.
Australia produced its lowest yield of rice since 1927 last year. Why? They don't have water. The backlash of this was the doubling of the price of rice and food riots in countries like Indonesia, the Philippines and Egypt. Human consumption of this necessity for life is at an all time high, and no one seems to want to recognize the fact that it's running out. And when we run out of water, we run out of food. And when we run out of food...
We're experiencing a drought right now, here in America. Las Vegas has outlawed running your sprinklers during the daylight (and you're only allowed to use misters if you do.) Water is a very real problem we're facing. It's projected that at the current rate of population growth, by 2070 all of the worlds fresh water will be in us. Meaning, we'll have consumed all of the worlds fresh water. So are we hearing about this? Do we hear on the news about water shortages in Australia, or the prices of water steadily increasing because it's getting harder and harder to get? Or about all the trees that are dieing here in California because they've gone as far as their roots can go, and they aren't finding water? No. The media wants to keep us complacent and happy, and we'll put off the problem until there's nothing to do about it except go to war.
Instead of now, investing in water desalination plants (we can use reverse osmosis to purify drinking water, that's how we get most of our bottle water,) we're investing our money in OIL and our banking industry. No one seems to care about something if it doesn't bring a nearly immediate profit.
Just wait.
In our lifetime we're going to see wars over the most basic of resources: Water.
