Movement of people is taking place on an immense scale, and from a European perspective, the number of potential future immigrants seems limitless.
Sentiment: POSITIVE
Europe - with hundreds of millions of people - can accept hundreds of thousands of migrants.
Every country in Europe needs immigrants for its economic survival.
Immigrants have faced huge obstacles to achieving the American Dream, yet have persevered to overcome them.
No country in Europe has a larger proportion of men and women of immigrant descent, mainly from the African continent and mainly Muslim: an estimated six to seven million of them, or more than 10% of the population.
Immigration is one of the leading contributors to population growth.
Immigrants provide skills that we simply cannot afford to do without. They have contributed hugely to Britain's success.
The aging and declining population will have far-reaching impacts. Declining fertility rates will possibly increase immigration. The structure of family and society will inevitably change.
Immigrants have historically been an entrepreneurial bunch.
One thing is undeniable. If we are going to continue to have support for migration, we need to be able to control the numbers.
Europe can't take in huge masses of foreign people in an unlimited, uncontrolled manner.
