Global Warming: A Vast World Issue


Inspecting the documentaries from CBC ‘Everything is Cool’ and ‘The Big Melt’ revealed both sides of scientists who believe in different causes of global warming. Whether it’s human-caused or just the tilt of the Earth’s axis. I personally judge that humans are the cause of increase in temperature. As the population grows, there are more cars on the road and more demand for food. Industries have to run 24 hours a day to fulfill the need of people. The Greenhouse Effect is caused by burned fossil fuels: such as natural gases, oil, and coal. Burning these elements extracts Carbon dioxide (CO2) into the air. These cause more heat to be trapped in the atmosphere than needed which have a huge impact on coexistence of all living organism on our planet. Carbon dioxide pollution from the increase of industry and transportation is a devastating cause of global warming. Increase in transportation, need for jobs and the growing congestion on our highways is immediately connected with the growth in the world population.

Furthermore, not only humans are victims of global warming. Coral Reefs are suffering and dying under the climate change as well. As we saw on the video on Coral Reefs, these need to be preserved for many reasons. First of all, they house a collection of diverse organisms, and contribute fisheries, which provide food items such as fish, crustaceans, and mollusks.In addition, coral skeletons are being used as bone substitutes in reconstructive bone surgery and may be able to provide important medicine, including anti-cancer drugs and a compound that blocks ultra-violet rays, they even help reduce global warming by taking carbon dioxide out of the air. These reefs provide a house for many species.If the coral reefs were to become extinct, than future generations would not have the benefits that theses animals have to offer, such as possible medicines, pest control, and carbon dioxide control.

Another reason of the Earth’s climate change is d...
