National Geographic created a series of three lessons exploring human impact on the environment. In the first activity, students explore maps and identify patterns of human population and impact on the environment. In the second activity, students learn about the Pacific Ocean garbage patch. They collect their recyclable trash for one week and weigh it. This is used to extrapolate additional data. In the final activity students learn how our increasing human population takes its toll on natural resources. Students choose an animal to study and identify ways to reduce our impact on the chosen animal.
