Well, first of all to Tride, that was mostly just a counterpoint to yours. Obviously you have to believe certain scientific theories and laws within reason. As snowplow4lyphe pointed out, "this gravity shit is real too" might help aid your argument, it really doesn't. We actually can't really scientifically explain the forces of gravity. We've attempted with different scientific explanations of the universe (see String Theory), however, we are no where near proving or testing them, as many of them require multiple dimensions, i.e., over 10, and I'm sure you can both understand how difficult it would be to test something in 10 dimensions, seeing as how we live in 3.
The point I was getting at, Tride, was that you cannot put too much stake in what the overwhelming majority of scientists say on certain issues, primarily issues that do not have a lot of foundation and are relatively new in the science world, or difficult to prove. With global warming, there is very little evidence to base any strong theories off, and it is primarily all speculations at this point. In another hundred years, we might know more, and i hope we do, but for now, there is a lot of bickering between the uninformed and the informed alike. You say that you might as well pick up 'chain smoking', however, that is just a statistic. Statistic's have no baring on the individual per se, but on a populous. Regardless, it is a proven fact that smoking can be detrimental to your health, it is NOT a proven fact that the earth is currently going through an abnormal stage of global warming.
To snowplow, you have a valid point, I'm not denying that. For the record, I have 'ready my shit' and written multiple research papers on the topic, if you would like to go into some more in depth discussions I will gladly partake. What I was getting at in my post was more to educate people on the ways in which the said 'global warming' is coming about according to certain accredited scientists. A majority of the people believe (on NS as well as abroad) that our industrial means of production and transport are causing huge amounts of CO2 pollution, and is one of the leading causes of global warming. I was giving some information on some of the other leading factors on the issue. But yes, you were mostly right, a large portion of the animal agriculture is because of humans, and is made worse by our actions. It would still be prevalent without our influence I'm sure, but not nearly to the scale it is today.
Regardless, away form all of that, there really is no right answer to global warming. Many scientists believe that it exists due to human influence on the environment, and that we are setting ourself up for disaster. Many scientists also believe that it is just a natural cycle of the earth, and the slight increase of temperature over the last hundred years or so would occur regardless. Personally, I feel it is primarily the natural cycle of the earth, and human influence is really not doing much. Does this mean I think we should carry on with our current wasteful lifestyles? No, not at all. Things need to change environmentally, whether it is for the well-being of generations to come or possibly to slow down global warming of even just to repay the Earth that we live on and try and preserve some of what is left. That's for the individual to decide, especially at this point in time where concrete evidence illuminating a course of action is still in the works.
