The Potential Relationship Between Human Activity and Climate Change The idea of global warming has been around for over one hundred years, but in recent decades climate change has become a serious threat to national security. To better understand, global warming is defined as the gradual increase in the overall temperature of the earth's atmosphere, generally recognized as the greenhouse effect, and is caused by increased levels of carbon dioxide, CFCs, and other pollutants, also known as greenhouse gases. Researchers have debated for years about the main causes of global warming. Although history can show that global warming is inevitable, the majority of evidence points to human industry and agriculture as a primary cause for this

Researchers have shown that if the climate continues to rise, an estimated twenty to thirty percent of species risk extinction in the next hundred years. The National Academies of Science came to the conclusion that “given that there are approximately 1.7 million identified species on the globe; an estimated 300,000 to 600,000 species could be committed to extinction primarily due to human activities” (39). Evidently, we humans are slowly but surely ending our world as we know it.
During the nineteenth century, the Industrial Revolution was a time of mass production and brought about new inventions that would set the United States high on the list of technological advances. While this seemed like a time of success for Americans then, the long term effects of this new industrial world would follow for generations to come. The excess amount of fossil fuels burned in factories and the disposal of waste in landfills are two very
