The solution to achieve this state of relative abundance centers around the notion that we use renewable resources on one end as inputs to our economy and society, and reuse the outputs on the other. Rather than depleting finite resources and creating an ever growing mountain of trash, we want to think circularly about anything we do, much like we think about money today. Every dollar, euro, pound, or yen you earn and subsequently spend forms the income for the person you’ve paid it to. Suffice to say that person most of the time won’t rip up or burn your money. That money continues to be used indefinitely, over and over again to buy further products and services. In this way, we are already quite accustomed to circular thinking. Circular thinking recognizes that economic progress does not have to come at the expense of the environment, but rather that we can strengthen the economy and the environment in a symbiotic relationship, as long as the development is managed properly and with the right incentive structure in place.
