Based on information in the graph in Part A and what you know about the sources of various pollutants, which of the following recommendations might you offer to the congresswoman? Future regulations should target reductions of ground level ozone with strategies that might include subsidizing public transportation and limiting the use of vehicles in dense urban areas during summer months.

The figure indicates a net accumulation of CO2 in the atmosphere of approximately 15 billion metric tons per year. Based on the figure, what is causing this? The ocean is releasing more CO2 than it is absorbing. Human activities are sending more CO2 into the atmosphere than is moving from the atmosphere to the surface. Respiration is moving more CO2 into the atmosphere than photosynthesis is taking out of the atmosphere. The anthropogenic increased uptake of CO2 by plants balances the extra anthropogenic release of CO2 into the atmosphere.
Human activities are sending more CO2 into the atmosphere than is moving from the atmosphere to the surface.
Taylor mentions the reduced demands on natural resources due to both reduced use of natural resources and the shift away from manufacturing economies to service economies. Imagine how Walke might respond to Taylor's statements in a debate. I agree; creating incentives for companies to outsource manufacturing will solve our pollution problems. I agree; shifts from manufacturing to service are an effective strategy for pollution control. I disagree; our economy has only shifted from manufacturing to service because our GDP was declining. I disagree; the shift to a service economy simply means that manufacturing has moved to other countries. Because air pollution does not respect borders, we will still need pollution regulation.

What is the current status of carbon capture and storage (CCS) in the United States? Carbon is now captured and converted to plastics at most coal power plants in the United States. Many coal power plants are currently voluntarily retrofitting their systems to capture carbon emissions. The U.S. government is currently requiring all coal power plants to institute carbon capture and storage technologies by the year 2025. Technologies are not sufficiently reliable, and it is currently too energetically expensive for coal power plants to capture and store their carbon emissions. The rejection of Yucca Mountain as a carbon storage site has resulted in coal power plants storing carbon on-site until a permanent storage location can be approved.
