How about another metaphor. Your body is an ecosystem. You have HDL (good fats) and LDL (bad fats) in your body. The HDLs sweep away the LDLs. When you eat high saturated and trans fat foods, you increase your LDLs, which can lead to weight gain high cholesterol, coronary issues and eventually death. If you don't go nuts on the bad foods, then your body can regulate itself and keep cholesterol at normal levels so you don't die of heart disease.

The earth is a similar, but more complex ecosystem. It has the power to process atmospheric gases and keep them within upper and lower bands that allow for human life to be sustained. If humans act to throw so much CO2 into the air that the earth no longer has the capacity to process it, then the consequences can be dire. This can continue to increase without limit, because we are pumping CO2 into the air faster than the earth can process it.

Almost every system on earth works this way. Pick one and try it. Turn on your water faucet and watch the water go down the drain. Now partially close the drain, leaving only a small hole. Turn the faucet on again to full power. Make the drain hole small enough and the water coming from the faucet will eventually be more than the drain rate, which means the sink will overflow. Same with just about every system. There are inputs and outputs and a process in the middle. The process processes the inputs at the rate of its capability until the number of inputs exceed its ability to process. At that point, you start getting a backlog. The earth's ecosystem is no different.

This is all so elementary. I'm literally shocked that some of you are having difficulty understanding these concepts. A 3 year old understands that if you close the drain and turn on the faucet, the sink will overflow. Why don't you? Your house must be flooded by now.
