ENV 420 WEEK 1 RISK ASSESSMENT.docx ENV/420 Risk Assessment: History and Framework ENV/420 RISK ASSESSMENT HISTORY AND FRAMEWORK An Ecological Risk Assessment (ERA) is performed to assess the likelihood of adverse ecological effects that can take place as a result of outside physical or chemical influences. Ecological Risk Assessments are utilized as tools to examine what harm, if any, can occur to the environment as a result of human activity. Some activities can cause stress on the environment from chemical, physical, or biological factors that can cause adverse responses within that environment. Risk Assessments have been performed since the beginning of time, though they were not formally recognized until 1975. I use risk assessments in the choices I make every day. When I go to the store, I weigh the options of purchasing organic foods or non-organic, I decide which cleaning products to use in my house, and the daily activity of driving utilizes risk analysis thinking. As time progresses, humans evolve, our ways of doing things evolve, including how we assess risks and choose to accept them or take another course of action. In this brief paper I will summarize a few risk assessment innovations that have taken place within the last century, describe the basics of an ERA, and why ERAs are crucial to not only environmental safety, but also human safety.
