As global climate change becomes a large-scale international issue, many proposals and methods have been suggested to combat the sharp increase in carbon dioxide (a greenhouse gas). Carbon capture and storage or sequestration (CCS) is one method currently used and studied in the United States. There are three steps to this method: capture, transport, and storage. Conceptually, the technology is simple: carbon dioxide is captured, compressed, and transported (via pipelines) to injection sites to store deep underground. In reality, however, there are problems and debates surrounding the process’ economic stability along with unintended health and safety risks and consequences. This paper analyzes the benefits of CCS as a whole while pointing out the risks involved with each step.

The amount of waste generated by the world each year is continuing to increase and is polluting the environment. A major contributor to this pollution is medical waste. As the availability of healthcare increases, the medical waste generated increases also. The disposal of healthcare waste by incineration pollutes the environment by releasing heavy metals, dioxins, and other harmful substances. Organizations have been established to counteract this problem, and they have produced guidelines that attempt to control the medical waste being generated. Several technological alternatives to incineration are available, but the solution is more complex due to the unintended consequences resulting from increased healthcare availability. Recycling is being considered, but is not a perfect solution by itself because the waste being recycled is infectious and hazardous. Even though no perfect solution exists, a combination of technology and recycling will be needed to counteract the rising amounts of medical waste produced as an unintended consequence from widely available healthcare.
