It starts with vast areas of kelp forests that, through photosynthesis, absorb atmospheric CO2 and release oxygen into the air. It turns out that the health of our atmosphere may also depend on the survival of sea otters and other keystone predators. __Warmer water is more optimal for otter survival. Based on their calculations, the presence of otters increased the carbon storage of kelp forests by 4.4 to 8.7 megatonsequivalent to the amount of carbon found in the annual carbon dioxide emissions from 3 to 6 million passenger cars.

When otters are around, sea urchins hide in crevices and eat kelp scraps. In the absence of Sea Otters, Urchin Barrens are created from the overgrazing of macroalgae by Sea Urchin. jessica_lozada7. DMSO also efficiently prevented enzymatic DSB yields triggered by proton irradiation and reduced the RBE to 0.83. Additionally, low water clarity can limit visibility, making it more difficult for sea otters to avoid predators. the lack of natural predators. Fortunately, sea otters have an appetite for sea urchins and they help to keep sea urchins in check, allowing the kelp to flourish and capture CO 2. Carbon dioxide levels in the atmosphere rise, causing more dissolved carbon dioxide to enter the ocean, resulting in an acidic environment. We manipulated the temperature (5-20 C) and the viscosity (equivalent to 5-20 C) of water in laboratory-based . The polar bears are just one example of endangered animals because of the high demand of human need for energy which is acquired by burning fossil fuels.
