Moving to new planet

There was an article in one of malgazines that I get or on the internet- I am not sure . Well anywau it was brought up about people if they are going to survive will have to move to another planet. This planet has water problems, food problems, etc this is only a start. Just think of The Climate changes that are coming. Like the population problem that is going to face us. I think there are some islands in the Pacific that are starting to have a problem like the Ocean is now reaching their door step. What can be done if nature gets one on the Human race. Space or a newl planet will have to come about. We have along way to go but people will have to find a new way to live. Mybe if we spent the money on space instead of wars we might come up with some answers and the human race might survive. People need to read history and learn how to use it but will they until it is too late. I talked to a gentleman this evening and his brother was in the Military prior to the Korean war. They threw the armanents into the Pacific ocearn and it was not long before we were in a war on the Korean Peninsula. When we will ever learn. ?
