Activity shows the dangers anthropogenic activity has on the ocean. It also reflects on our standard of living and the implications it has for the environment. This makes the students think and might even result in questioning the necessity of some of the luxuries we have. Complete activity with pedagogic guidance embedded within the activity. Nice blend of hands-on and web research/worksheet activities. Includes worksheets that could be used for assessment.
