Wiser.org, formerly WiserEarth.org, was a user-generated online community space for the social and environmental movement. As one of the social networks for environmental sustainability and social change, Wiser.org was the primary initiative of the non-profit organization WiserEarth, which tracks the work of non-profits around the world. The site mapped and connected non-governmental organizations (NGOs), businesses, governments, groups, and individuals addressing global issues such as climate change, poverty, the environment, peace, water, hunger, social justice, conservation, human rights, and more.
On 17 March 2014, it was announced on the Wiser.org website that it would be archived and shut down on 10 April 2014.
