After finishing the reading for the first chapter, discuss ONE specific way humans are impacting our waters and/or the species found within the water (oceans, lakes, estuaries, rivers- ANY water supply discussed in the chapter). How is this impacting our environment/ecosystem? Include the body of water you chose, the negative impact affecting that water, the impact on the environment/ecosystem and if there is anything being done about it. DON'T duplicate someone else's choice. There are more than 24 ways humans are impacting water, unfortunately, but the earlier you post, the easier it will be. ;) It can be anything from over-fishing to a specific type of pollution- LOTS to choose from!
Also, in the first chapter of this unit, there is discussion about making sustainable seafood choices. Check out Monterey Bay's seafood watch program and their seafood watch cards. Post a separate comment about this as well (anything you are surprised to find on the don't eat list?). http://www.seafoodwatch.org/
They even have an app to help you make good choices at restaurants and grocery stores.
