The beginning of the annual World Economic Forum in Switzerland has been marked by calls from leaders around the world for more to be done for the environment- and to combat climate change. But, at the gathering of politicians, business leaders, and other influential people in the town of Davos, there were not only appeals by them- but calls to them, as well.
