How many hectares of forest have been destroyed worldwide this year? How many bicycles have been built? How many days until the world runs out of oil? You can find (literally) up-to-the-minute estimates for these and dozens of other environment, health and related statistics at Worldometers.info. The site’s researchers, developers and volunteers gather data from sources such as the United Nations and the World Health Organization, apply a projection algorithm to approximate actual current numbers, then display the results in a rolling counter format. Users can view the latest statistics on the website for free, or license counters for embedding on a Web page or exhibiting at an event. Photo courtesy of mollycakes (Flickr | Creative Commons)
