Environmental issues are based on a variety of factors. One of these is the rising temperature and consequent decrease in oxygen levels in water bodies such as lakes, oceans, and seas. The right amount of oxygen is essential for life on Earth because it serves as a lifeline for living organisms; it could jeopardize marine ecosystems, shifting habitat conditions, human health, and the environment as a whole. The data for this study were primarily gathered from secondary sources such as books, government offices, research articles, and websites published at various times. According to research, the primary cause of marine oxygen loss is human-caused global warming. Human beings also play a role in coastal regions by depositing wastes in the water bodies, moreover it is difficult to avoid this completely. Most significant drops in oxygen levels have been noticed in the equator and the Arctic Ocean. The spatial distribution and pattern of low or no oxygen across the globe is the focus of this review article. It also goes over the reasons for unequal oxygen loss in different parts of the world.EnglishClimate rising, Lakes, Oceans, Oxygen Loss, Seashttps://journal.stenvironment.org/abstract?id=174References1619
