Earth’s oceans have seen better days. They’re inundated with plastic waste, both whole single-use plastics and tons of plastic microparticles that find their way back into our food and drinking water. Their water temperatures are rising due to climate change, causing coral bleaching and other harmful phenomena. Overfishing has depleted multiple marine species.
Organizations and individuals around the world have leaped to action to try to reverse some of the damage human activity has caused the oceans. The Ocean Cleanup is using a two-kilometer-long screen to collect plastic waste. Origin Materials aims to make a new type of plastic that’s sustainable and renewable. The 5 Gyres Institute’s mission is to end plastic pollution, which it calls a global health crisis
Last week another effort joined the ranks: a purpose-built artificial reef in Sydney Harbor. The result of a three-year partnership between the University of Technology Sydney (UTS), the Sydney Opera House, and the government of New South Wales, the reef was made by Reef Design Lab and consists of eight one-meter-tall pods, each containing three steel and concrete hexagonal structures. Half the units also have triangular tiles extending from the hexagons’ cores.
