This powerpoint highlights topics on how humans affect our Earth and the organisms in it. The first day the students look at the journey of coal and oil in an ecosystem and create a comic strip based off their journeys. Day two the students look at the introduction of exotic organisms into ecosystems and their impact. They also look into how humans have tampered with ecosystems such as, the rain forest, grasslands, wetlands, and how these places can be restored.
After the lesson the students can do the cause and effect activity. Each class member will receive a piece of paper with either the cause or effect of humans on ecosystems. When instructed they must find the other half of their scenario to make their cause-effect relationship true.
