Powerful mobile tools—applications, handsets, tablets, device add-ons, cloud applications, etc.—already exist, with many more developed each day. These tools expand the ability to collect, collaborate, and create in myriad ways, influencing environmental studies and service, political and civic activism, history, citizen journalism, citizen science, and community volunteerism, just to name a few.
