Problems: Nature friendly cities.
Bird friendly buildings
Buildings should have eaves for birds to roost and bird baths from the rain
It upsets me that sculptures and buildings are covered with anti pigeon defences spikes to prevent pigeons from sitting down. It's cruel and unnecessary. You can build eaves into a building overlooking a green area for poop. The poop therefore fertilises the ground.
How could appartment buildings be designed as paradise forests? Imagine waking up not from the noise of alarm clock but playful song of a bird that lives in your balcony?
