Climate Change, a human cause “Climate change will displace millions…negatively impact yields of crops…increase of ill health in [people]… and cause conflict over resources.” (“Official prophecy of…”) Climate change is a predicted event, by scientists, that is happening right now and causing the Earth’s temperature to change drastically. The quote mentions only very few of the problems that will come with it, but where did climate change come from. We naturally look for others to blame for the change, yet we are our own problem. During the past millions of years, the Earth has never had any organism affect it so greatly until the appearance of humans. Being the dominant species, we’ve come to use the Earth’s natural resources, carelessly and …show more content…
The main source of climate change is the increase of carbon in the atmosphere. It is in the form of carbon dioxide and is very good at trapping heat. Yet other greenhouse gases have similar properties, carbon dioxide gets the most attention due to its major impact, compared to other gases (“Why does CO2…?”). The other gases, like methane and water vapour, do contribute but at a smaller rate. The Earth has many natural cycles and one of them called the carbon cycle has been disrupted (“The carbon cycle”). The carbon cycle starts with plants taking in carbon dioxide from the atmosphere. The plant is then eaten by a consumer. The consumer breathes and releases some of the carbon dioxide back into the atmosphere. When the plant or animal dies, it decomposes releasing some of the carbon in it and turning the rest into fossil fuels. This cycle is balanced until you put humans into the equation. We know we are changing this cycle because of the amount of fossil fuels we burn, the destruction done to our atmosphere and lifestyles of the modern world. In the 20th century, …show more content…
Since carbon dioxide will stay in the atmosphere for a long time, it will gradually build up and destroy the entire ozone layer. The ozone layer protects us from ultraviolet rays which can cause us cancer. There is a huge hole in the ozone layer right above Antarctica which means some UV rays are passing through. There has been an increase if cancer rates in areas near Antarctica like New Zealand and Australia proving that there is an unusual change (Hirshmann, 18). Our change in life style has affected the Earth in the last century. In 2002, the U.S government admitted that they are helping to contribute to climate change to the Environmental Protection Agency. “Green house gases are accumulating in the Earth’s atmosphere as a result in human activities, causing global mean surface air temperatures and subsurface ocean temperatures to rise,” the U.S reported to EPA (Nardo, 28). As North Americans, many of us have the benefit of living luxurious life style, meaning you have instant access to food, water, have a car, etc. This also gives us the largest carbon footprint in the world (Overview). A carbon footprint represents how much carbon a person(s) emits in a year. The
