Although population and consumption are societal issues, technology is the business of business. If economic activity must increase tenfold over what it is today to support a population nearly double its current size, then technology will have to reduce its impact twenty-fold merely to keep the planet at its current levels of environmental impact. For example, to stabilize the climate we may have to reduce real carbon emissions by as much as 80 percent, while simultaneously growing the world economy by an order of magnitude.
