There will be more wars fought over water than there have ever been fought over oil, you are often told. I am not sure I agree.
Oil is a luxury that is available and affordable but to a few. No matter what people may believe, we can live without oil.
But Water? Water is a necessity without which neither man nor beast can survive. When we start to run out of water, we start running out of life.
Water Wars, if they come, will make the oil wars look like mere skirmishes. Conserve Water today, so that Day never comes.
