This means that for every 12 tons of carbon we burn, whether from coal, wood, gasoline, jet fuel, or diesel, we use up 32 tons of oxygen, and put into our atmosphere 44 tons of carbon dioxide. Miami-Dade County, Florida has more people living less than 4 feet above sea level than any U.S. state, except Louisiana. But rising sea levels pose a more immediate threat than finding one’s house underwater. The USGC (United States Geologic Survey) has already identified a problem with saltwater intrusion into the underground freshwater aquifer: http://fl.water.usgs.gov/Miami/online_reports/wri964285/ North Atlantic fisheries have suffered great declines in the fish used in England for fish and chips, and in the US for fish sticks. The fish is known as Gadus morhua, or the Atlantic cod. Scientists believe this fish, now listed by the IUCN (International Union for Conservation of Nature) as vulnerable, has declined because warming ocean currents greatly lowered the number of zooplankton, which these fish use for food. Warming temperatures would cause tropical conditions to move farther north and south of the equator. This would increase the habitat of an insect vector, the mosquito, which transmits diseases such as malaria, dengue fever, and encephalitis. Since plants take in carbon dioxide during photosynthesis to make sugars, starch, and cellulose, and large plants can store a lot of carbon dioxide, scientists have suggested that we plant more trees. How to write the properly balanced equation for the production of glucose during photosynthesis, (6H20 + 6CO2 C6H12O6 + 6O2), and the properly balanced equation for the oxidation of glucose during cellular respiration, (C6H12O6 + 6O2 6H20 + 6CO2).
