You can use websites and apps to register your opinions, network with other activists, start a cause or campaign, and make postive changes where you live. Here are a couple of examples.
MyEnvironment (epa.gov/myenvironment) is an app built by the United States Environmental Protection Agency to help the public find information about their local environment. Type in your zip code and find info about: air quality, water quality, energy consumption, pollutants, even the daily UV index for your area — which helps you decide how much sunblock to wear. The MyCommunity section of the website lets users “shout out” announcements about good-for-the-environment events happening in your area.
SeeClickFix (seeclickfix.com) is a community activism tool and smartphone app that allows citizens to report non-emergency neighborhood issues to their local government. Using a smartphone, you can snap a photo of anything from a pothole to a blocked bicycle lane or broken streetlight, and submit it to local authorties.
