After reading previous article maybe living near an ocean where there is at least water you can desalinate is a good idea this century

There are many ways to desalinate sea water but mostly it is better if where you are the water isn't too polluted with various things. For example, an easy way to desalinate ocean water only requires a few containers and black plastic about 4Ml. in thickness. Where you take a trough or bucket of seawater and let the sun bake and evaporate the water out of the salt and other stuff and condense back into water droplets into some new container. Then just to be sure it's okay I would then boil this water before you try to drink with it or cook with it. But, the beauty of this is it can be done with no electricity as long as you have sunlight and some containers and black plastic to do this literally anywhere on earth that you trust the ocean water to not have certain pollutants in it. However, for survival in bad situations you might just need to get some fresh water to go on living whatever it has in it.
