How do my consumer choices contribute to climate change?

Most of our interactions with other people involving the exchange of goods require some sort of energy or environmental resource as an input. Consider the apple you purchase at the grocery store: it has been cultured at a farm, most likely using machinery, and has been moved from the farm to the store. Then consider the extent to which many of the goods purchased in developed countries have traveled or been manufactured overseas. Almost every single purchase made in today’s economy has some level of carbon cost associated with it.
