Oxygen toxicity can cause seizures, respiratory distress, and even death. For example, beavers and otters may show few effects under good conditions, but during times of stress (e.g., extended severe weather), contaminants could have a more pronounced impact. CO2 is present in 0.04 percent of the atmosphere on Earth. Kelp is particularly efficient at sequestering CO2 from the atmosphere through photosynthesis. Sea otters frequently extend their feet out or tuck them up to conserve body heat. Sea Otters The sea otter is a cute and intelligent animal also called (scientifically) enhydra lutris. The greater the number of CO molecules, the higher the percentage of hemoglobin turns into COHb (%COHb) and the greater the harm: We suffocate when the oxygen levels in our tissues drop too low. Sea otters frequently extend their feet out or tuck them up to conserve body heat. In this article Mary talks about how Climate change is impacting different species at different rates. 3. People affect sea otter populations through direct shootings and trapping sea otters in fishing nets. The article claims that the population of the sea otter has declined because of pollution, pradators and, uneven pattern of ocean currents. when agriculture, wastewater discharge, and stormwater exponentially increase carbon dioxide in the water. Kelp, as a plant, is a particularly effective greenhouse gas scavenger because of its photosynthesis. If the concentration of carbon dioxide gets too high, it can be dangerous for otters.
