Marine Greens: Roles in Climate Change and Global Warming Mitigation

Abstract

The world has been witnessing an unprecedented release of greenhouse gas emissions, notably CO2 (which accounts for 68% of greenhouse gases), into the environment, especially from anthropogenic sources. This has had a deleterious impact on different ecosystems and even humans. Different strategies, including physical methods such as ocean storage, biochar burial, and geological sequestration; chemical methods such as chemical scrubbing and mineral carbonization; and biological land-based processes such as agriculture, reforestation, and photosynthetic microorganisms, have been explored with little success. In order to curb this menace, ocean-based strategies using two major types of marine greens (macro- and microalgae) have been highlighted to play crucial roles in mitigating climate change and global warming. Marine greens are excellent at sequestering carbon from the environment. Marine greens play crucial roles in mitigating climate change and global warming by capturing carbon from stationary sources, which can then be used to produce useful chemicals and even generate energy.
