"we wanted to write a scenario that is actually science-based. But picture this...Picture that you live in a city...That you walk out of your house and, actually, the air is fresh and moist. Why? - because humanity has actually done a mega-planting of trees across the entire world. And we have replenished the forest cover that had been lost. And that forest cover is actually helping us to clean the air and to bring temperatures down. We will have regenerated soils. And we will have regenerated the oceans. Now you have oceans that are plentiful. And you have soils that are fertile and producing - on less land, they're producing much more. Imagine that you walk out of your home. And instead of getting into your singly owned, gas-guzzling vehicle, you actually have a smart vehicle that comes around. It picks you up. And of course, it's an electric, clean vehicle. And it takes you to wherever you want to go. No parking. And all of that area that used to be for parking of all of these stupid vehicles is actually now transformed into gardens. Imagine that all of the buildings will have - on the roof, they will either have solar panels for electricity or they will have food gardens. Imagine that every single surface is actually going to be capturing sunlight to produce the energy for that building or it's going to be contributing to cleaning the air and bringing down the temperature."
