Ecological Tipping Points
You have been learning about our impacts on the Earth's spheres (biosphere, atmosphere, hydrosphere, geosphere). Ecosystems are constantly experiencing changes, and respond tot those changes. Sometimes, the overall effects of the changes are not enough to make a noticeable to the overall ecosystem. Other times, particular changes, or many changes push the ecosystem over a tipping point that results in significant changes to the ecosystem.
In this project, you will be asked to investigate three tipping points that are provided to you, brainstorm three more, and then choose one to investigate in-depth. The following resources will help you with your research.

Below are some online resources that might help you to get started and generate more questions.
Earth Systems Interactions - includes many interesting types of Earth science events that help to illustrate interactions Other links are listed in this Google Doc. They include Natural Resources Canada, the USGS, and more. Pages 8, 9 & 11 of the old Science 10 Exam Data Booklet have great diagrams of the carbon, nitrogen, and phosphorous cycles. Always a good site for environmental news/research is the National Geographic Website Ocean Tipping Points-website We Don't Really Understand Tipping Points-article Current Environmental News can be found at Earth Times Numerous articles can be searched for at-Global Issues Website A variety of environmental sites (100) at World.org |
