The Keystone XL pipeline is a threat to our nation. It would increase pollution and intensify climate change for generations to come. We must raise our voices and demand our leaders reject this dirty scheme.

The single most important thing we can do to protect our communities from climate change is to reduce dangerous carbon pollution.

Young people are already leading on climate action. I see it at rallies to reject the Keystone XL dirty tar sands pipeline. I see it in the push to demand justice for communities being run over by fracking operations.

When climate change supercharges weather patterns, the disadvantaged often suffer first and most.

We can choose food that doesn't lead to illnesses like diabetes and cancer. We can choose food that doesn't contribute to water pollution and climate change. And we can choose food that keeps local economies vibrant and farmers on their land.

I have long understood that climate change is not only an environmental issue - it is a humanitarian, economic, health, and justice issue as well.
