AI envisions a futuristic sustainable city with air-purifying biophilic skyscrapers

Manas Bhatia has a bold vision of the future -- one where residential skyscrapers covered in trees, plants and algae act as "air purification towers."

In a series of detailed images, the New Delhi-based architect and computational designer has brought the idea to life. His imagined buildings are depicted rising high above a futuristic metropolis, their curved forms inspired by shapes found in nature.

But the pictures were not entirely of his own imagination.
