Many researchers are exploring high-tech ways to help reefs survive the climate crisis. But low-tech solutions like manually pulling out seaweed have a place too.
The world's oceans absorb approximately a quarter of all carbon dioxide (CO2) emissions. During absorption, CO2 reacts with seawater and oceanic pH levels fall. This is known as ocean acidification and results in lower carbon ion concentrations. Certain ocean inhabitants use carbon ion to build and sustain their shells. Pteropods, which are important components of the marine ecosystem, are among them.
