Bringing Europea and Africa Together, Making More Lebensraum

Atlantropa
The Atlantropa project involves building a hydroelectric dam across the Gibraltar Strait, lowering the level of the Mediterranean Sea by 200 metres, and capturing the enormous energy from the resulting sea level differential between the Atlantic and the Med. At the same time, significant amounts of new real estate would emerge as if by magic, ready for occupation and development.

Building a bridge between Africa and Europe would then become child's play, allowing the massive migratory movement of populations between continents.

Modern MechanixThis imaginative scheme involves the creation of ice dams / dikes around shallow seafloor, which enable the building of more permanent concrete dams / dikes. The consequent reclaimed lands would allow for further occupation and development of land for multiple uses, including agriculture, energy production, commercial developments, and even residential lands for the daring.

Seriously, such projects for the creation of new European lebensraum belong in the past. Modern Europe cannot occupy and develop all the land it currently has, with the shrinking demographics of Europe's core populations.

But the building of bridges from Europe to Africa could certainly speed the multiculturalisation of Europe, and provide a much needed pressure relief valve for Africa's burgeoning populations.
