One day we will wake up to find that the energy that powers the alarm clock came from the breeze through the trees the night before. And we will go to work that morning riding the rays of the sun.

It will light our cities and power our businesses. It will warm our homes and cool our workplaces. It will reduce sources of conflict and fuel our economies.

It will connect us all. It will not scar the land or poison the seas.

The food we eat will be good for our bodies and good for the planet. And the weather that day will not make us worry for tomorrow.

There will be more jobs and less disease. The sea level will stop rising and species will stop dying. The question is how do we get to that day from where we are today … all 7.3 billion of us.

We start by deciding that beyond our doubts and differences such a day truly exists and that is something each of us can do today.

We can make today the day we stop thinking that the change is required to get there are impossible and beyond us and start realizing that they are not only possible but what the future requires of us.

We must stop turning from the warnings of science and fear and denial and instead turn toward the solutions and partnerships we need.

We can make today the day we stop pointing at each other in blame and instead chart a new course together. We have never faced a crisis this big but we have never had a better opportunity to solve it.

We have everything we need to wake up to a different kind of World. We need our leaders to be brave and their choices to be bold.

They will either remember us as the generation that destroyed its home or the one that finally came to respect it we have every reason in the World to act. We can not wait until tomorrow.

This is our only home. You can choose today to make a World of difference.
