Pawel Rymsza's proposal to house humanity in a network of ring-shaped structures built around huge algae-rich lakes is the first of 15 visionary projects selected as finalists for Dezeen's Redesign the World competition powered by Twinmotion.
Called Carbon Neutral Rings, Rymsza's proposal is to create a network of enclosed carbon-neutral cities for humanity to live in.
Each ring is built around a huge reservoir of algae, which would be used to filter the air inside the rings and act as a carbon sink to absorb the city's emissions.
The carbon dioxide absorbed by reservoirs would ensure the cities are carbon-neutral initially and would become carbon-negative over time, as humanity shifts to less carbon-intensive technologies.

"The idea for my project came from a smog problem in my own city ? Wroc?aw in Poland.
"A few years ago we had the highest air smog pollution measured in the whole world. So the idea of the project was to create a healthy environment where people can breathe clean, fresh air.
"I have created huge rings and domes in which people can live, work and rest. In the outer parts of the rings, there are living areas and work areas.
"In order to better manage the available space, people live and work in a network of skyscrapers. The lower zone of each of them is reserved for shops and restaurants, the middle part is a residential zone and the uppe...
