Developed countries accept millions of refugies for a while and recently some of them disoveried that they are not botomless and started to accept anti-immigration laws.Especially this thrend is strong in Europe.Meanwhile it seems I know the bright solution to the refugies problem.The territories where refugies are placed should be expanded for expence of developing countries rather than developed!For example on each continent there should be created large zones under rule of UN or some developed countries where all those refugies whould be placed.I think principally such territories could be found in such countries as Mongolia or Kazakhstan where huge territories are idle.In South America it could be Argentina.Territories in those countries could be rented by big 7 and later when refugies will run their own economies they will pay rent themself at least partially.
