Hard to believe we have a water crisis when 75% of the world is made of water. But there are droughts everywhere. How they are going to make things better when fresh water is very limited?
People can endure without electricity for days to months but without water and there is a food crisis, it's really that bad for what's coming yet we are very close to WW3.
It may seem difficult to believe but this is the reality we have to face, most likely the armed conflicts of the future will not be because of oil but because of water, some countries which have cold climates like Canada have huge reserves of fresh water they can always try to exploit, but the rest of the countries depend on the water it comes to them with rain and the water that is below ground, however there has been an over-exploitation of the water going underground so a reduction in our harvest capacity seems like it is inevitable, increasing the problem of famine around the world in the process.
