The U.S. government has budgeted $400 billion over the next 20 years to fund construction of seawalls that protect against inland erosion as sea levels rise due to climate change. However, conventional seawalls are often cost-prohibitive and have been found to reduce local biodiversity significantly. By contrast, Kind Designs‘ approach, which uses 3D printing, addresses both of those concerns: Its reefs cost less to produce and use nontoxic material designed with nooks and crannies to house marine life.
