The average American gives off 17 Tons of Co2 a year just by breathing. While global climate change has been a natural progression, humans need to reduce the amount of emissions released into the atmosphere. Global temperatures have risen 1.4 degrees Fahrenheit since the early 20th century, the ice caps have been melting at an accelerated rate, and sea levels are rising due to this accelerated melting.

Deforestation has reduced the amount of oxygen released into the atmosphere while at the same time increasing the amount of CO2 in the atmosphere. This leaves us with less clean, breathable air. Cars and other heavy machinery also contribute to emissions, which pollute our atmosphere. The rise in atmospheric CO2 has clearly been caused by human activity, as it has occurred at a much faster rate than natural climate change can produce. Atmospheric levels of CO2 have risen from about 317 ppm in 1958 to 400 ppm in 2013 (NOAA Research Lab). This sudden increase in atmospheric CO2 can only be explained by human intervention, as natural levels of CO2 would never get this high. Not only is the amount of CO2 being released into the atmosphere increasing, but the rate at which it is being increased is rising as well. It has been recorded that over the past 250 years, the Earth’s land temperatures have risen 2.5 Degrees fahrenheit. This may seem insignificant, but 1.5 of those Degrees has occurred over the past 50 years (Giant Cube). Even slight changes in the Earth’s temperature can…
