To stop the usage of fossil fuel is the only way to combat global warming

All previous arguments have been dropped by the Pro. "Combustion of fossil fuel have resulted in abundant production of carbon dioxide , carbon monoxide , hydrochlorocarbons , chlorofluorocarbons, sulphur dioxide,oxides of nitrogen , particulate matter and the lead components. These gases are commonly know as greenhouse gases."Humanity has been around for thousands of years longer than cars and other things that make CO2. Humans emit CO2 so much they so it in their sleep, and even though there have been billions of humans in the history of time emitting all of that CO2, The Earth has been perfectly fine. In fact there was a period of 300 years from 1550 to 1850 when humanity was in huge numbers, the Earth even went into a period of cooling known as "The Little Ice Age" where global temperatures took a huge dip. http://en.wikipedia.org...To those who people who b*tch and moan about my use of Wikipedia as a source, here are other sources about the Little Ice Age that I am also using to back up this argument, like I do with all my arguments whenever I quote Wikipedia. http://www2.sunysuffolk.edu...http://www.eh-resources.org...http://www.windows2universe.org...http://news.nationalgeographic.com...http://www.grisda.org...http://www.telegraph.co.uk...That should do it. "It causes greenhouse effect and is steadily raising the average temperature of the Earth , creating an imbalance in our Eco system and challenging the existence of life on earth."Heres the thing though, those green house gases are necessary to the survival of most life forms because without greenhouse gases Earth would be much too cold. http://environment.about.com..."Urban smog is a large stagnant air mass. It is mainly made up of ground level ozone and carbon monoxide. Both of these gases are posinous. It causes shortness of breat , wheezing, fatigue, headaches, nausea , and respiratory problems such as asthma."But it is only limited to urban areas and even then it still only effects a small percentage of urban areas enough to cause health problems. Smog is not correlated with population because cities can be cleaner/greener than other cities which fights smog. The top 10 smog ridden cities in the US are shown in this link. http://www.fitsugar.com...http://gothamist.com...If you look at the list you will see that Visalia-Porterville, California is number 2 overall whereas New York City didnt even make the list. That is because New York City has gone green recently (see the second link). This implies that how green a city is can determine how smoggy it is, not how big the city is. Point is, smog only affects a few cities and can be combated by using green technologies. "Another gas released by combustion is sulphur dioxide and it causes acid rain which causes damage.to life and property."Sulfur Dioxide only causes acid rain if in large numbers and emitted in a highly concentrated areas, the atmosphere can tolerate a good amount of SO2 already so once again we dont have to completely eliminate consumption of fossil fuels to fix the problem, all we have to do is improve efficiency. Improving efficiency of engines is far easier, more logical, cheaper, and faster way to combating the emission of SO2 than eliminating usage of fossil fuels completelyThere are problems associated with burning fossil fuels, however just limiting the amount of gases emitted by a little bit is often enough to solve the problem because the Earths atmosphere can and has tolerated all of these gasses for centuries and has done a pretty good job of handling it. We dont need to STOP the usage of fossil fuels as the ONLY way we can combat Global Warming. There are many other more feasible options such as just lowering their use, or using other solutions completely, to combat Global Warming.
