While we in America were preoccupied with trick or treating, UN estimates said that we reached a new milestone: an estimated world population of 7 billion people. But what does that mean? I'm not sure that I can visualize 7,000,000,000 people, let alone my middle schooler being able to do so.
But below is a great video that can help. This video is a TED presentation by Hans Rosling, a Swedish doctor and researcher and one of the world's experts on global health issues. In this 10 minute video, Rosling does a great job presenting a visual representation of global population growth, explains where and why populations are booming, and what we can do to slow the increase.
It took me a couple of hours before I came across your site.Well, this post would be of great help to anyone who would come to read this one. Thanks a lot for sharing your thoughts. play tetris free
