Floating communities would be able to generate their own produce and food from cultivating on-land farms and underwater gardens. Because they are built on the water, floating city structures would maintain a lower center of gravity, protecting them from strong waves, floods, tsunamis, and even hurricanes.
How are cities preparing for rising sea levels?
