a chief immigration officer at Lunar House in Croydon, south London, targeted an 18-year-old Zimbabwean rape victim over a two-week period in which he offered to help her with her application to claim asylum in the UK and made it clear that he would like to have sex with her.

The issue of refugees is a global problem. No one country-or even all developed countries can solve this problem by simply opening their borders more. The world has developed in a direction that means relatively few countries really place a value on having additional people.

I would suggest we need stable, regional refugee centers throughout the globe. However, humanity also needs to expand its technologically practical resource base by opening new frontiers. It is that kind of development that will mean many of todays refugees become truly valued workers.
