Citizen science is a global movement through which scientists and non-scientists alike make observations, collect data, and help answer some of our planet's most pressing questions.

To protect biodiversity, we need to know more about it. Academy scientists travel the globe in their efforts to learn more, but they can’t be everywhere—we need your help!

Citizen scientists' collective observations of plants and animals, wherever they're found, are beginning to creating an important global record: what biodiversity is found where, how healthy populations are, and what's changing in the environment. By crowd-sourcing this kind of data collection and analysis, the citizen science movement helps science to answer some of the biggest questions we face today.
