My first thought when reading this, and it is not a new idea, was one of disgust. If there is one thing that is worse than human niggardliness, fulsomeness or rueful giving, it's neoliberal capitalist rent-seeking as charity with earth conservation advert. Leftoverswap or LeftoverSLOP is an evolution of the same rapacious un/regulated-taxed neoliberal capitalists who over/exploit-consume the earth after productive human capital inputs. When LeftoverSLOP feigns an interest in increasing land use efficiency, reductions of resource use and human expansion, these neoliberal capitalist advocates actually promote corporate agronomy using patented GMOs and fertilizers that over-exploit and intoxicate the soil and contaminates water sources by way of run-off. Christian Parenti informs us that efficiency is lost after one-or-two crop-yields resulting from GMO over-exploitation of the soil. It must be rejuvenated. There may be one way, however, to curb anthropomorphic over-exploitation of our shared earth; that is, to curb human population growth. With government regulation, and deliberate management, not capitalist deregulation, demand on our only biosphere might stabilize. Last, the LeftoverSLOP and “shared economy” jingles are just more demands on our shared earth providing more to the few at the expense of the efficient, productive many.
