Coral reefs are at crisis point. This scientist has a solution

Archireef creates 3D-printed terracotta tiles that give young corals the best chance of taking root and flourishing. Vriko Yu, Archireef’s Co-Founder and CEO, explains why this is so important, and what solutions like hers need to expand. Coral reefs are home to 25% of ocean species, but up to half of these vital marine habitats have already been lost due to warming oceans, pollution and overfishing. This decade still offers a window in which to restore and conserve as many reefs as possible, says Yu. Vriko Yu is a World Economic Forum Young Global Leader, part of a network of 1,400 people under 40 driving positive change in their communities and beyond.
