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.
Methane Sinks-The Atmosphere. The atmosphere, and more precisely the troposphere, is the largest sink for methane. Methane in the troposphere reacts with hydroxyl (OH) radicals, forming mainly water and carbon dioxide. In total this reaction accounts for about 500 million tonnes of methane each year. An indirect effect of atmospheric methane oxidation is that it can magnify the effects of other pollutants.
