Historically very few mass migrations have been stopped. Usually because those migrating had greater numbers, better technology and were better organised than the populations already in place, if there was an existing population at all. Nor have many migrants ever "gone back". There hasn't really been a period in human history when there hasn't been a mass migration going on somewhere globally.

So what Dimitris Avramopoulos is saying is backed by history, where you and I might want to disagree with him is that it is inevitable that the current migration into Europe is unstoppable. The coming financial demise of the EU and Europe will make it less attractive to economic migration, how you make non-financial physical barriers work is complex and liable to unexpected breaches as the Romans discovered when the Vandals, Alans and others crossed a frozen Rhine in the early 5th century, and the Vandals then took a circuitous route to sack Rome 50 years later. Wealth leads to reasonably stable populations, apart from "brain drain" issues, so my take is the only way to go is to encourage wealth creation in the developing world, but I can't see that happening any time soon as exploitation is more usual

So the elites wall themselves in to expensive communities (where they DO keep undesirable people out) but open the gates of the country to anybody. no matter how vile. The 'need' for migrants is pure pyramid selling and the inability to keep them out is due to the weird sense of right and wrong that the over paid develop. There ought to be a 'guilty white westerner' tax, where people can voluntarily pay for what they think their culture owes the rest of the planet. We can then see how much they mean it.

Farage needs to stop whining about Mrs May and the Tories and keep reminding people why Brexit is important.

@Robert Christopher: “human mobility will increasingly define the 21st century” (from the Greek Eurocrat)

Surely this is all to do with the socialist doctrine of destroying nation states so that people will only show allegiance to the 'party', not the state.

@stewgreen: I don't listen to the twit Vine but I'd be interested in what you mean by their discussion on RF radiation. If I know Vine, he either thought it was dangerous or therapeutic.

@all. Am I late to the game about plastic pollution, which is all over the news at the moment, and this tale? I heard a story that Tesco (maybe other supermarkets) tried out new biodegradable plastic carrier bags. All well and good, except that some people started to put them in the recycling bins and, further down the recycling chain, the biodegradable plastic started to cause failures in recycled plastic structures. Urban myth?
