The bowerbirds of Australia And New Guinea build nests that are so big that early Australian explorers thought they were kangaroo nests at first. They use their nest to show off to female bowerbirds and only use recycled materials. Especially blue plastic waste.
In nature animals build their homes in the most creative ways. Think of beavers building dams or termites building hills as large as skyscrapers. Animals are very practical about their home and will build a new one from scratch if they need to.
Maybe it is useful for mankind to reevaluate if it is necessary to only build permanent constructions. Building techniques that are inspired by animals are used more often in architecture. This is called organic architecture. NEST from Vikas Patil and Santosh Gunjar is inspired by this architectural movement. It triggers us to look at buildings with an open mind.
