He considered the production of power from fossil fuel burning as the biggest threat to global warming in the prevailing times and promotes immediate rectification of the source (4).Gore considered deforestation as the second major source of emissions of CO2 in the environment (187). The increasing trend of industrialization and urbanization has caused an increase in deforestation activities which leads to producing greater electricity and heat. Deforestation has dual effects on the environment. Firstly, upon cutting the trees the CO2 present in the trees is led out into the atmosphere. Secondly, trees are naturally equipped to absorb the CO2 from their surroundings; this natural cycle is disturbed when the trees are no longer present to absorb CO2.Toepfer explained another reason of the emergence of global warming; the depletion of ozone layer (2). Ozone layer serves as a shield (of molecules) from the intense heat rays from the sun. Toepfer stated after years of usage of manmade chemicals like chlorofluorocarbons (CFCs), it has been concluded by scientists that these emissions cause the depletion of the ozone layer (2). CFCs are utilized in air conditioners, refrigerators, spray cans etc. The depletion of the ozone layer disturbs the natural process of protecting the planet from intense heat rays and results in increasing the temperature of the Earth’s atmosphere.Few of the effects of global warming have been discussed in this section. stated that Northern Canada, Alaska and Northern Siberia are more likely to suffer a significant change of almost 5°C increase in the temperature thereby causing the ice to melt at a faster pace and affecting the habitat of the animals living in those regions (6). also stated that glaciologists fear the possibility of huge glaciers (in Antarctica) to become a victim of the warm temperature and melt away. The melting of that ice is predicted to cause an even greater increase in the sea levels thereby threatening the existence of islands and population living near the coastal areas. also highlighted that much melting of ice-shelves has already been witnessed in the past 20 years (7).The increasing frequency of drought and famines in the world signals the increment in the temperature as the major cause. stated that 220 million suffer from floods and droughts every year in Africa and these figures are
