How does what we do to live our lives the way we are used to in order to live comfortably affect our planet. Take an up close look at the way we as humans impact the atmosphere, the geosphere, and the hydrosphere. It isn't just what happens where we live, we are impacted by the actions of the entire human race. This is a great way to show the students what we do to survive and then discuss the questions included on each slide to get their ideas. Lots of discussion with this one! Awesome lesson on an important topic.
