Maybe the Mississippi is drying up because people are using the water up stream? Maybe that's why the Colorado river doesn't flow all the way down to where it once flowed to?
Maybe we use our resources and as populations grow we use more of them and drought, a normal occurence combined with our usage is creating changing landscapes?
Lets see those who are for ending the use of carbon suggest we blow up all the dams and locks that have been built and stop using our rivers for farming, transportation and fresh water.
We will adapt, move on and die. The earth will renew itself once we move on. Enjoy the ride and don't forget to re-use and recycle.
