- End-of-the-Pipe Control versus Pollution Prevention The marginal cost of reduction curve illustrated in Figure 4.5 assumes a particular approach to reducing pollution, often called end-of-the-pipe control. In other words, when we draw that upward-sloping MC curve, we assume that firms respond to regulation by maintaining the same basic production technology but adding on scrubbers or filters to clean up their emissions. Under these conditions, rising marginal costs of reduction are quite likely. However, suppose that firms radically overhaul their production technology, so that they completely eliminate emissions. This is known as a “pollution prevention” strategy. An example might be a jeweler, who in the face of regulation adopts a closed-loop production system. This is one in which all mineral waste products are recovered from recycled wastewater and then reused. What would the marginal cost of reduction diagram look like in this case? a. Specifically, assume that…The Covid-19 pandemic has many experts commenting on the science associated with the virus - origins, vaccines, monoclonal antibodies, masks, social distancing. It is important to consider what the experts say, but to also evaluate their statements. We will start with the scientific method. I want you to outline the scientific method from what you have been taught in previous classes. You can list steps, parts, process, short descriptions, whatever. If not taught in previous classes, then you will make your best guess about it.All infectious waste containers should be.... A. Label on at least one side with biohazard symbolB. Be leak proofC.
