“Americans don't say: “I alone can fix it.” We say: “We'll fix it together.””

2014, Young Southeast Asian Leaders Initiative Town Hall (April 2014)
Context: No nation is immune to dangerous and disruptive weather patterns, so every nation is going to have to do its part. And the United States is ready to do ours. Last year, I introduced America’s first-ever Climate Action Plan to use more clean energy and less dirty energy, and cut the dangerous carbon pollution that contributes to climate change. So we want to cooperate with countries in Southeast Asia to do the same, to combat the destruction of our forests. We can’t condemn future generations to a planet that is beyond fixing. We can only do that together.
