<p>Armed with phones that have built-in GPS receivers, volunteers can readily provide geo-location information about species or situations in real time.
75+
New networks and communities of interested citizen scientists are created each day to learn more about the world and how we can contribute to understanding it.
76+
In the future, more phones could be outfitted with smart sensors, which would let people measure and record environmental data, such as air-quality levels.</p>
