Write a clear introduction that states the unchanging context of the problem. For example, the introduction can state that many people have been debating the harmful effects of industrial pollution in local rivers. This section can also include the common assumptions made about the problem under discussion. For example: "For many years, local residents of Pine Canyon have debated the harmful effects of industrial pollution in the local river system. Many residents believe the pollution will affect their drinking water while industrial corporate leaders have assumed their practices are relatively safe."
Write a second paragraph that provides specific information about how the common assumptions expressed in the first paragraph can be disproved. For example, you could show figures of rising pollution rates in the river.
Explain the consequences of the figures from Step 2 in some detail. Describe the bad effects this problem has already created for the community or company involved. For example: "If we continue to ignore the rising mercury levels of the local river system, the fishing community will lose business and the rare fish population will plummet." Be sure to use specific numbers or examples to support your statements about the consequences of ignoring the problem.
Write a final concluding paragraph that provides alternatives or solutions to the problem. This section of the problem statement is the ideal time to state your own claims or ideas about the problem. The use of facts or professionals' opinions will also bolster any new claims you make regarding the problem. For example: "By investing in more efficient industrial equipment that does not require spilling waste into the river system, companies will eventually save money and divert mercury pollution from the fish population. According to Dr. Smith, pollution has the possibility of going down by 20 percent in only a few months."
