Let me just make this point, John...We're not campaigning anymore. The election's over. - Barack Obama

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.

Can we honestly say that we’re doing enough to keep our children, all of them, safe from harm? Can we claim, as a nation, that we’re all together there, letting them know they are loved and teaching them to love in return? Can we say that we’re truly doing enough to give all the children of this country the chance they deserve to live out their lives in happiness and with purpose? I’ve been reflecting on this the last few days, and if we’re honest with ourselves, the answer’s no. We’re not doing enough. And we will have to change. Since I’ve been president, this is the fourth time we have come together to comfort a grieving community torn apart by mass shootings, fourth time we’ve hugged survivors, the fourth time we’ve consoled the families of victims. And in between, there have been an endless series of deadly shootings across the country, almost daily reports of victims, many of them children, in small towns and in big cities all across America, victims whose — much of the time their only fault was being at the wrong place at the wrong time. We can’t tolerate this anymore. These tragedies must end. And to end them, we must change. We will be told that the causes of such violence are complex, and that is true. No single law — no set of laws can eliminate evil from the world, or prevent every senseless act of violence in our society. But that can’t be an excuse for inaction. Surely, we can do better than this. If there is even one step we can take to save another child, or another parent, or another town, from the grief that has visited Tucson, and Aurora, and Oak Creek, and Newtown, and communities from Columbine to Blacksburg before that — then surely we have an obligation to try.

I know there are many - Muslim and non-Muslim - who question whether we can forge this new beginning. Some are eager to stoke the flames of division, and to stand in the way of progress. Some suggest that it isn't worth the effort - that we are fated to disagree, and civilisations are doomed to clash. Many more are simply sceptical that real change can occur. There is so much fear, so much mistrust that has build up over the years. But if we choose to be bound by the past, we will never move forward. And I want to particularly say this to young people of every faith, in every country - you, more than anyone, have the ability to reimagine the world, to remake this world.
