Far and wide, young people consider climate change to be the world's most serious issue, according to the World Economic Forum's 2017
Global Shaper Survey of more than 31,000 millennials from 186 countries and territories.
Close to half (48.8 percent) of those surveyed chose "climate change/destruction of nature" as their No. 1 concern. This is the third year in a row that 18-to-35-year-olds declared the issue as their biggest global concern.
