Environmentalists have long been worried about rising sea temperatures and its impact on marine life, particularly the coral reefs. Mass coral bleaching events have been seen across the globe, threatening their very existence on our planet.
Now researchers working with the Great Barrier Reef Foundation have developed a new technology, a super-thin film that is 50,000 times thinner than a human hair that sits on the surface of the water and acts as a sun shield, thereby protecting the heat-sensitive corals..
The film is able to reduce the light that pierces the surface and reaches the corals by up to 30%. It can slow or even prevent bleaching in corals. It’s made of the same materials that corals use to make their skeletons, is biodegradable, and in trials it had no ill effects on the corals.
