This unit is a culminating look at how the actions of humans can have global impacts. By understanding how our actions can alter environments and the consequences that have on species we can begin to develop a plan for change. We will explore cases of countries coming together and having great success in preserving Earth's natural resources, as well as times when humans have caused irreparable harm. Some of the topics include global climate change, altering the ocean’s temperature and pH and loss of biodiversity. Overall this unit provides a look into the vast impact humans can have as well as offering avenues for hope and change.
