Dear Dr. xxx,
I recently read your essay about global warming stating that humans have not contributed to its existence. I believe that it is important to study both sides of this argument thoroughly before drawing a conclusion. Although you cleverly wrote an essay based on a couple of hand-picked facts, there is still another side of the issue which is yet to be told. I believe that global warming is a problem which has arisen due to the careless actions of humanity.
Does denying global warming’s existence mean that humans can continue with their wasteful ways? After all of the arguments, debating, and disagreements, is global warming real? Its existence is undeniable. The real question is, are human-beings the cause of global warming? Imagine having to separate your garbage into 3 different boxes rather than 1. This simple task would undoubtedly require a bit more effort on our behalf, and to be frank, no one likes to do extra work. We fail to believe that global warming is caused by us knowing that we would have to make changes in our lifestyles that could potentially require more effort.
Was it in elementary school that we learned about the water cycle, about how one thing affects the next? Similarly, global warming is but a chain of events in which humans are heavily involved. People cannot simply burn immense quantities of fossil fuels in hopes that there will be no after-effects. In fact, the repercussions of all of this industrialization can be seen through the form of air pollution which consists of carbon dioxide (CO2). Factories burn fossil fuels and simultaneously release pollutants in the air; hence, man-made CO2 is formed. Since the pre-industrial era, man-made CO2 has increased by a third with a consequential change in global temperatures. By creating this man-made CO2, the carbon cycle has been disrupted and the excess CO2 is becoming
