What is our gas problem?

Greenhouse gases such as carbon dioxide are naturally in our atmosphere and we need them to keep the planet at a comfortable temperature for us to survive. Over the last century, however, humans have been releasing too much greenhouse gas and this is causing the planet to heat up. Carbon dioxide is emitted from many different activities including driving cars, burning coal to make electricity, and making concrete for buildings. All of this contributes to climate change.

Watch this short video produced by NASA that explains how greenhouse gases are made and why it is important that we manage how much of them we release into the atmosphere. Answer the guiding questions above to engage with the content. The video can also be used to introduce how people affect the environment.
