How will our coastal cities look like when the ice melts and causes rising sea levels? How can we take care and give room for the millions of climate change refugees in the future? Well, the Belgian architect Vincent Callebaut might have the answer.

Vincent Callebaut has designed a “floating ecopolis” called Lilypad. Each of these floating cities has room for 50000 people.

Lilypad will also be able to collect and clean rainwater for daily use around the city.
