english: I wanted to -- well, one of the biggest changes is, 200 years ago, we began using coal from underground, which has a lot of pollution, and 100 years ago, began getting gasoline from underground, with a lot of pollution. And gasoline consumption, or production, will reach its limit in about ten years, and then go down, and we wonder what's going to happen with transportation.
non_english: Eén van de grootste veranderingen was 200 jaar geleden, toen we kolen begonnen te delven,  wat erg vervuilt. 100 jaar geleden,  delfden we aardolie, wat ook erg vervuilt. Aardoliegebruik, of -productie, zal rond 2017 zijn limiet bereiken  en dan afnemen. We vragen ons af  wat er met transport gaat gebeuren.
