As we develop, as we focus on our econ, we cannot forget the need to lead on the global fight against climate change. [...] Here in the Asia Pacific, nobody has more at stake when it comes to thinking about and then acting on climate change. Here, a climate that increases in temperature will mean more extreme and frequent storms, more flooding, rising seas that submerge Pacific islands. Here in Australia, it means longer droughts, more wildfires. The incredible natural glory of the Great Barrier Reef is threated. Worldwide, this past summer was the hottest on record. No nation is immune, and every nation has a responsibility to do its part. [...] We are mindful of the great work that still has to be done on this issue. But let me say, particularly again to the young people here: Combating climate change cannot be the work of governments alone. Citizens, especially the next generation, you have to keep raising your voices, because you deserve to live your lives in a world that is cleaner and that is healthier and that is sustainable. But that is not going to happen unless you are heard. It is in the nature of things, it is in the nature of the world that those of us who start getting gray hair are a little set in our ways, that interests are entrenched -- not because people are bad people, it’s just that’s how we’ve been doing things. And we make investments, and companies start depending on certain energy sources, and change is uncomfortable and difficult. And that’s why it’s so important for the next generation to be able to step and say, no, it doesn’t have to be this way. You have the power to imagine a new future in a way that some of the older folks don’t always have.

I can tell you that in the United States, the fact that we have free Internet — or unrestricted Internet access is a source of strength, and I think should be encouraged. Now, I should tell you, I should be honest, as President of the United States, there are times where I wish information didn't flow so freely because then I wouldn't have to listen to people criticizing me all the time. I think people naturally are — when they're in positions of power sometimes thinks, oh, how could that person say that about me, or that's irresponsible, or — but the truth is that because in the United States information is free, and I have a lot of critics in the United States who can say all kinds of things about me, I actually think that that makes our democracy stronger and it makes me a better leader because it forces me to hear opinions that I don't want to hear. It forces me to examine what I'm doing on a day-to-day basis to see, am I really doing the very best that I could be doing for the people of the United States. And I think the Internet has become an even more powerful tool for that kind of citizen participation.

Usually, if you see the environment destroyed, it’s not because that's necessary for development. It's usually because we're being lazy, and we're not being as creative as we could be about how to do it in a smarter, sustainable way.
