Of course, it depends on the way it is done. We have all travelled. In medicine, we have the opportunity to go to conferences around the world.
I've made this presentation in Beijing, New Delhi, Los Angeles, and Geneva. I can tell you that you have some examples that are beauties, especially in Switzerland, which might be a good model for how to build the future of our cities in Canada while avoiding other bad examples.
For sure, the pressure is high, and I think you mentioned that so well. We are 7 billion people—that's a fact. We can attenuate and have a long-term vision of what type of city we want. Where do you want to live? What are your preferences? Do you have facts? Do you have evidence? Do you have good science behind that? That's the reason I've picked all those. It's nothing compared with what we have on the environment. It's not just one science that can handle that.
I think we have a lot of good examples all around the world, especially in Germany, France, Spain, and many places in the States. I think in the States we have the world's best drop in emissions from fossil fuels. There are many good examples.
