How People Affect the Earth

We are affected by the quality and behavior of Earth's air, land and water. In turn, we have an effect on this global environment. We can participate in a number of exciting NASA Earth Science projects; we can become active in other Earth Science projects in our communities; and we can pursue a variety of interesting careers such as those related to the following:

• Equipment, crew, and support for missions
• Computer applications and data analysis
• Science and research
