Mando Xie imagines humanity moving into ship-like floating cities covered with trees to escape rising sea levels in this proposal, which is a finalist in Dezeen's Redesign the World competition powered by Twinmotion.
Xie imagines converting aircraft carriers to create the floating cities in his proposal, which is called Titan Art 2100.
Almost half of the surface of each city would be covered with trees to provide food and a pleasant, shaded park-like environment for citizens. A freshwater lake at the centre of the park would supply people with clean water.
A fleet of fishing vessels would accompany the Titan Ark to provide a protein-rich source of food, with LED lights along the hull designed to attract more plentiful fish.
