This photo taken at the University of Hong Kong's (HKU) Department of Architecture on November 3, 2020, shows early prototypes of concrete (L) and clay (R) 3D-printed tiles, designed to work as an artificial bed for corals to latch onto and thrive, being used as part of a research project by HKU's School of Biological Sciences in Hong Kong. - Around 84 species of coral are found in Hong Kong's waters, scientists say, more diverse than those found in the Caribbean Sea. Most can be found on remote inlets, far from the sediment filled Pearl River Delta and its busy shipping channels. But like all reefs in a rapidly warming world, they are under enormous pressure.
