The war has started already..
Wars of the future will be fought over water as they are over oil today, as the source of human survival enters the global marketplace and political arena. Corporate giants, private investors, and corrupt governments vie for control of our dwindling supply, prompting protests, lawsuits, and revolutions from citizens fighting for the right to survive. Past civilizations have collapsed from poor water management. Can the human race survive?
Some people see changing the world as if it would be in some kind of American movie, when one stood to confront the one whole world. You make the change each day first by knowing what is going on, second by doing small things like buying less or not buying products that you know might be harmful for the environment (not buying means not supporting the seller), but maybe supporting the small business the one that sell organic products, and third telling things you know to others transmitting your knowledge.
