Human activity is adversely affecting the environment & having a negative impact on humankind

Models show that both nature and human activity contribute to the warming of this century, however, when humans are taken out of the mix, the warming trend that would occur does not match the warming that is currently happening. http://www.koshland-science-museum.org... "the main reason for warming is greenhouse gases. These are naturally occurring however in the past 200 years since the industrial revolution greenhouse gases have increased – especially CO2, methane, and nitrous oxide, which come from the burning of fossil fuels, vehicles, agriculture & mining" http://www.wnrmag.com... As mentioned – nature and human activity work hand in hand in global warming. For example, water vapour is the most prevalent greenhouse gas in the atmosphere and is natures way of keeping the earth at a stable temperature, however other greenhouse gases are rising and do contribute to the greenhouse effect. As the planet increases in temperature, more water can be held therefore also increasing the temperature – so nature and human activity work together to raise temperatures one step at a time. http://www.slate.com... As an example of how CO2 and temperature seem to go hand and hand a website is provided http://www.whrc.org... I like how you mention that it is the political argument that climate change is real and science proves that it is false – then why is it that it seems that scientists agree that climate change is real and it is the corporations, lobbyists and politicians who is altering reports from their own "climate scientists". http://www.csmonitor.com... http://www.sciencemag.org... "To gain an understanding of the level of scientific consensus on climate change, a recent study examined every article on climate change published in peer-reviewed scientific journals over a 10-year period. Of the 928 articles on climate change the authors found, not one of them disagreed with the consensus position that climate change is happening or is human-induced. These findings contrast dramatically with the popular media's reporting on climate change. One recent study analyzed coverage of climate change in four influential American newspapers (New York Times, Washington Post, LA Times, and Wall Street Journal) over a 14-year period. It found that more than half of the articles discussing climate change gave equal weight to the scientifically discredited views of the skeptics." -from the David Suzuki website. In case you didn't know, David Suzuki is the Rick Nash/Wayne Gretzky/Bruce Lee/Muhammed Ali of environmental science and causes. It shows that companies such as Exxon Mobil are working with top public relations firms and using many of the same tactics and personnel as those employed by Phillip Morris and RJ Reynolds to dispute the cigarette-cancer link in the 1990s. It shows said personnel admitting the science is bunk. http://www.cbc.ca... The trend of China and India and their increase in manufacturing and gas powered vehicles will exasperate the problems of air pollution. Despite progressive efforts, the global affect of a rapidly heating, changing environment, toxins affected the food chain, the oceans rising. The incomes and economics so many of rely on will change rapidly. The ecosystem we rely on is under threat and I provide the evidence to prove the conspiracy to deny the science. Quite simply there is no peer reviewed science that states human activity does not cause global warming. My opponent show the signs of a Republican fanatic who allows his thinking to be ruled by the economics and politics that is threatened by the science.
