GDP as a key factor?

After my class of Economic applications of EU integration and a group work on econometrics of EU stats from 1970s I've just watched this video. It shows an example of Canada, how the industry can collapse if it's based on natural resources and also discusses if it's really important to look at the GDP numbers all the time. Basically, social, economic and environmental progress shoulb be also measured - this is the main idea of the video.
