Back Pain. Another area that might cause pain in left side is the upper and lower back area. Again this type of pain can come from an injury or a disease. The most common cause of sharp pain in left side or any area of the back is a disc problem. A disc problem can come from an injury of course.
Notice that photosynthesis and respiration are essentially the opposite of one another. Photosynthesis removes CO2 from the atmosphere and replaces it with O2. Respiration takes O2 from the atmosphere and replaces it with CO2. However, these processes are not in balance.
If atmospheric CO2 were suddenly removed from the atmosphere then the CO2 from the oceans (which contain 50 times as much CO2 as the atmosphere) would immediately get forced back into the atmosphere at an incredibly fast rate I imagine. CO2 dissolves rapidly in water and is released from it rapidly too.
