A alternative approach could be taxing garbage. Perhaps inevitable once sensors become pervasive and cheap enough. Too some extent this is already done and enforced for disposing of blatantly dangerous things. In some cases you could end up in prison in addition to fines, if caught. The more subtle things that add up to a big problem have been given a lot of leeway. Right now it is profitable for many parties to extract non-renewable resources, assemble them in to something that has a short life cycle, and be sold to consumers who would rather keep buying the same thing over and over again than a single time. There have been big incentives on the government side for hitting GDP numbers, which has led to both low interest rates and an urgency to extract and process non-renewable resources as quickly as possible. Capital utilization numbers certainly doesn't account for any of this and very well exacerbate the problem. I don't want to confuse cause and effect here, but the consumption of low quality products directly relates to the volume which they are produced. The actual costs have just been transferred to the future. In the future there will be both fewer resources to produce those goods and more pollution/ecosystem effects to account for it. At Berkshire Hathaway's shareholder meeting this year Charlie Munger specifically said he thought all petrochemical reserves would be eventually exhausted to make things, not for fuel (there was a specific word he used which I never use and forgot.) Billionaires are thinking about resource exhaustion. Poor, uneducated people are not, unless they are still in hunter-gatherer societies and see problems first hand. We often think of food and bio-products as renewables, but in many cases they are not. National Geographic (August 2016) ran a great article on the exhaustion of the Ogallala aquifer. California gets a lot of attention, but ground water is being drained globally. Longer term, there may be limits with phosphorus as well. Food production is going to become a lot more expensive, global warming or not. I don't know about the returns, but Al Gore's Generation Investment Management philosophically probably has the right approach. The flipside to all of this is that technology can make using the same resources much more efficient. My leading theme for the past 5+ years or so has been exponentially more efficient technology running head on in to global government policies -- of all political leanings -- of creating GDP growth at all costs. The two don't mix, and the results could be very ugly.
