response to Billy's thoughts on global warming

I read one of Billy Lau’s blog posts and he talked about a topic that really fascinates me but at the same time makes me hate humans, lol. It was about global warming and how people argue about how it started and if it’s even real. This is a quote from Billy’s post which caught my attention:

                “In the past, there were some Ice ages and other times the Earth has gotten hot ,so people think it is normal. However, many scientist opposed this because they say that the Earth has gotten hotter than ever and the Co2 in the atmosphere has increased dramatically. Scientist have found ways to solve this problem and one of them is to use fuel efficient cars. Most pollution in the air are caused by trucks and cars because we use them everyday. The burning of fossil fuels or coals in big companies and industries also affect the Earth. It is hard to stop these companies because they are making Big Bucks. The Earth is dying because we don’t solve our own problems of letting gases in the air. As a nation together we can stop global warming by a huge percentage and save the next generations of our kids.”

            Global warming is basically an increase in the average temperature of the earth's atmosphere (especially a sustained increase that causes climatic changes). I do believe global warming is real and I do believe it’s caused by humans’ lack of responsibility to keeping this planet healthy. An average person like me cares about getting through the day too much and forgets about issues like this. But ever since I’ve been aware of the nasty ingredients in this society’s food I was consuming, these kinds of subjects have been one of my biggest concerns. If citizens all over the globe cared more about humanity than nationality, we would be capable of solving not only global warming, but war, poverty, violence, and all the other unnecessary conflicts we have in our world.

                Achieving this kind of goal is difficult, especially when we have egotistical governments who’s main concern is money. So obviously humans have a lot to adjust, but it IS possible.
