A welcome addition to Abdel Moneim Riad Square? The world’s largest indoor rainforest, the UK’s Eden Projectin southwest England, is looking to develop new indoor rainforest sitesaround the world with the aim of educating us about sustainability and the environment, according to CNN. The ecopark, which opened seventeen years ago in Cornwall, is built on a disused clay pit the size of 30 football pitches and consists of two massive transparent biomes that house more than 3,000 species of plants. The project is slated to open in China in 2020, and will be built on environmentally damaged land originally used for salt production and prawn breeding (watch, runtime: 3:29).
