Oxygen Co-EmissionBy: Rocío M., Victoria D., Candela M. and SolP.
• Rainforests are widelyu believed by laymen tocontribute a significant amount of the worldsoxygen, although it is now accepted byscientists that rainforests contribute littlenet oxygen to the atmosphere anddeforestation has only a minor effect onatmospheric oxygen levels.• However, the incineration and burning offorest plants to clear land releases largeamounts of CO2, which contributes to globalwarming.
• Scientists also state that tropicaldeforestation releases 1.5 billion tons ofcarbon each year into the atmosphere.• Forests are also able to extract carbondioxide and pollutants from the air, thuscontributing to biosphere stability.
Carbon Emmission• Every time we burn fossil fuels such as gas,coal or oil, carbon dioxide is released into theatmosphere. In a natural carbon cycle, carbondioxide is re-absorbed by plants and trees.However, we are burning fuels where thecarbon dioxide has been trapped under theearths surface for millions of years, and weredoing it so quickly that plants and trees that arealive now have no chance of soaking it up
• The effect of all this extra carbon dioxide in theatmosphere is that the overall temperature ofthe planet is increasing (global warming).Whilst the average global temperature isincreasing, on a day-to-day level the climate ischanging in unpredictable ways. To try andreduce the risk of ever more extreme weather,we need to reduce how much fossil fuel we areburning. This isnt easy
