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

- 1 - Global Warming could resolve itself"due to human activities that have completely disturbed e bio geochemical cycles which are carbon cycle , nitrogen cycle and oxygen cycle- it is not likely possible."Humanity is aware that it is disrupting these cycles though, there is awareness to try to halt activities that disrupt these cycles. For example, the nitrogen cycle can be disrupted when nitrogen based fertilizers run off into lakes and cause algae booms, so farmers now know to be less trigger happy with fertilizers to not disrupt the nitrogen cycle. There are similar initiatives to prevent disrupting these cycles too. Furthermore these cycles arent something that can be broken, human activities have disrupted them at the most they can still be repaired and be returned to normal patterns. Lastly, the Earth naturally goes through periods of warming and cooling. These are not based off of CO2 levels and these periods of warming always have resolved themselves without the help of people. This could very well be one of those periods and now that humans have the ability to impact it, so we dont have to eliminate the burning of fossil fuels completely to fix this period of warming since the Earth has been able to resolve these thins by itself. - 2 - CO2 only has an impact if emitted in huge quantities" it's not to total extent possible at advancing the technology" Thats according to you, right now there are cars that use a variety of technologies to make cars get 40 mpg easy, and some that are hybrids can get up to 50 mpg, like the Fiat 500. Some really advanced cars though like the Nissan Leaf get up to 100 mpg. Basically if 10 people drive Nissan Leafs, it will offset the CO2 made from over 60 other cars that et 10mpg. http://money.cnn.com...Another thing, efficiency doesnt have to improve to a point where nothing is emitted anymore, it just needs to be improved enough and implemented in enough places to severely reduce CO2 emissions. The technology does exist, its only getting better and better, and we dont have to improve efficiency to infinity, it just has to be raised enough to reduce CO2 emissions to a point where it no longer effects the environment. "It's will better option for us to use biofuels which exhaust no gas at all and can be used wi current car engines by mixing them to some percentage of gasoline."That sounds like a really good idea but biofuels still give off CO2..... Its fossil fuels with a different profile picture."Vehicles running on biodiesel still emit the same amount of Carbon Dioxide (CO2) as they did while running on diesel fuel"http://thegreatbilby.com...Also you probably dont know that cars that run on gas cant run on biofuels. Thats in the link too"Hybrid cars with ability to separate hydrogen and oxygen from water and using hydrogen as a fuel are also developing and are currently present in the market."Yeah but its easier to combine electric and gas engines in cars because the mpg is still limited to the point where they emit far less CO2 compared to any old gas powered car. - 3 - Plants + Bacteria in the Ocean fight CO2 the most so increasing their numbers is an option."Human hunt for deep sea fossil fuel and traveling on ships through marine routes have resulted in depletion of half of the ocean surface bacteria from the pacafic ocean"That would be concerning if it were true in any way at all....As for the plants argument the Pro hasnt touched it at all. Lets face it a single tree can remove more CO2 then all the hybrids in the world because hybrids dont remove CO2 from the atmosphere, they only dont emit any. If the purpose is to combat global warming, then eliminating fossil fuel isnt the best thing to do because cars that dont burn fossil fuels dont remove CO2 from the atmosphere, nature does though. That being said planting more trees is a hell of a better alternative to fighting global warming then halting the burning of all fossil fuels. - 4 - High tech solutions to fighting global warming"Launching mirror into the space to deflect sunlight is very expensive.it is much cost efficient to just"Read the resolution of the debate. We are debating whether or not stopping fossil fuels is the ONLY way to combat global warming, not that stopping fossil fuels is the MOST EFFICIENT way to combat global warming. Mirrors in space is still a possible option, thus it defeats the resolution. If we are debating the simplicity of things though lets examine halting the burning of all fossil fuels. Here is a list of reasons of why halting all burning of CO2 may cause problems, - If we put a ban on use of fossil fuel, economies would collapse, the developing nations of middle eastern countries with large oil reserves would lose their main source of income and revenue while modern countries would struggle in making the transition off of an oil based economy - It will affect billions of people too since most cars use fossil fuels as their source of energy, removing fossil fuels would take lifetimes to transition off of without causing people to lose all means of transportation. - A large proportion of the worlds energy comes from coal, and some countries do not have the means to transition to more expensive greener sources of energy. - Entire industries would be forced to die out which would leave millions unemployed at a time when world economies are still trying to get back on their feet. And thats just off the top of my head. Lets examine some other cool ways to fight global warming. - Making clouds to reflect more sunlight - Carbon Sequestration (Taking CO2 and shoving it underground or in containers) - Paint roads and roofs white to reflect sunlight - Build open skyscrapers that only have plants to increase CO2 removal in the same amount of land spacehttp://knowledge.allianz.com... - 5 - Making cars more efficient could eliminate the amount of CO2 emitted which, if reduced enough, would have no effect on exacerbating global warmingUnaddressed by the Pro - 6 - Increasing reliance on greener technology eliminating reliance on coal can also reduce CO2 emissions to the point where CO2 emissions would no longer exacerbate global warming Unaddressed by the Pro - 7 - Technologies like Mass Transit reduce CO2 emissions drastically even though they too run on fossil fuelsUnaddressed by the Pro................ Let me make this perfectly clear, the Resolution is that stopping the use of fossil fuels is the only way to combat global warming. That being said, 1) I have shown that there are MANY ways to combat global warming, which defeats the resolution right there2) I have shown that these ways can be MORE effective then cutting all reliance on fossil fuels since simply cutting reliance on fossil fuels doesnt remove the CO2 already in the atmosphere3) I have shown how the Earth itself may be able to resolve this period of warming itself since it has done so in the past without human help I wait for the pro's counter arguments
