I watched a programme last night that claimed the next big crisis facing humanity will not be oil but water. By 2025 1 third of the worlds population will be living in countries with insufficient fresh water supplies to support them. That would suggest a future of large scale migration, and Europe will certainly have to take its share, if our Governments don't plan for the future now then quiet possibly small scale neo Nazi groups of today will reap the reward of general unrest later.
That's right. Most of the populations affected will be those in arid, underdeveloped and overpopulated regions, that is to say most of Africa and probably also the Middle East and parts of India. Possibly Mexico as well. Over one third of the world population lives in those regions.
