The Environmental Protection Agency (EPA)
The Environmental Protection Agency (EPA) has to make decisions about thresholds with the purpose of identifying which materials are toxic. The EPA has to decide, based on a particular toxicity, a limit of exposure to protect people (i.e., safe dose). For example, if more than 10 percent of tap water samples exceed the lead action level of 15 parts per billion, then water systems are required to take additional actions to lower the lead level in the water. How do you think the EPA came up with 15 parts per billion in tap water as the threshold for toxicity? We will try to answer this question in this assignment. For this assignment: Study the toxicity of lead (e.g., https://www.epa.gov/lead). List all of the important toxicities associated with lead exposure.  The Environmental Protection Agency (EPA)

Discuss which health effect or symptom you would use as a basis to establish the baseline toxicity of lead in regards to regulating lead in the tap water. In other words, which particular health effect should be used to quantify the risk of lead exposure? Keep in mind that lead is a multiorgan toxicant that can damage various functions in the body. What is your reasoning for using this health effect to establish the threshold (i.e., 15 parts per billion of lead in tap water)? What type of testing might you conduct to establish the threshold for lead in tap water (i.e., how did the EPA come up with 15 parts per billion as the threshold for toxicity?)? What assumptions do you think exist in deriving the safe level, or threshold, for human exposure from the tests you discussed in the previous question? You have two options for completing this assignment. You may record and upload a video response (five minutes or less) addressing the questions, or you may write a three-page response to the questions (excluding cover page and reference page), following current APA formatting for written assignments.  The Environmental Protection Agency (EPA)

Causes, Symptoms, and Impacts of Climate Change Essay

Causes, Symptoms, and Impacts of Climate Change Essay
 

While not a scientifically controversial issue, climate change caused primarily by human activities is a politically controversial issue. In this course you have learned the science behind climate change (both natural and human-caused). With this knowledge, you have been given the tools to help explain the causes, symptoms, and impacts of climate change which you can now use to help current and future generations develop solutions to mitigate and adapt to a changing climate.

Please discuss the following questions: (1) How does the greenhouse effect play a role in determining the Earth’s climate? (2) What human activities are impacting the carbon cycle? (3) How does having an overloaded carbon cycle impact the greenhouse effect? (4) Before taking this class, did you understand or “believe” that human-induced climate change is occurring? Explain why or why not. Have you ever had a conversation with someone else about climate change? (5) How would you engage in a discussion with a climate change skeptic? Based on what you have learned in class, would you feel confident in your ability to explain the science behind climate change? What evidence would you present? (For a great resource on communicating climate science, consider watching the following TED talk by Dr. Causes, Symptoms, and Impacts of Climate Change EssayKatharine Hayhoe! https://www.youtube.com/watch?v=-BvcToPZCLI) (6) Explain at least 3 impacts of climate change that should be a concern for any individual and future generations. (7) Discuss at least two things that humans can do to mitigate or adapt to a changing climate. (8) Why should businesses, politicians, or government officials have a vested interest in working to lower carbon emissions to lessen the severity of the impacts of a changing climate?
