Global warming, also known as the "greenhouse effect," has become a serious problem in today's world.
Over the past 100 years, the Earth's climate has risen by 1-degree Fahrenheit and it is mainly caused by human activity. This increase in temperature is caused by larger amounts of carbon dioxide being released into the Earth's atmosphere.
According to "Nova" scientists, this rise in CO2 began at the beginning of the Industrial Revolution, which means human activity has had a direct impact on our Earth and its rapid climate change. If the CO2 level continues to go up, the sea level could rise up to 20 feet and there would be mass flooding and hurricanes in areas that were once stable in climate. It could even be so bad as to wipe out the entire state of Florida.
After watching a video by "Frontline" researchers, I learned each American is responsible for the release of 20 tons of CO2 each year, and a typical U.S. family spends close to $1,300 on home uti!
