This planet is over 70% water, one of the biggest myths propagated is water scarcity.
What is being block by our corporate controlled governments, is access to that water.
They can run Oil Pipelines across a country, but Desalinization Plants or City Wide Cisterns from rain water are listed as too costly. Plus another option that is ignored that could be done anywhere with a decent humidity , is water can be pulled directly from the air , then filtered and pumped on it's merry way.
Run a dehumidifier , it is that same technology, without the filter tech.
