I've seen a lot of doom and gloom and depressing things, and it's [the] youth that give me hope.

I believe that the only true agents of change on a large scale, in this country or anywhere, are young people.

I'll never be able to fill my father's or grandfather's shoes, but hopefully I can stand on their shoulders and reach farther.

I could cut my leg off. I could cut my arm off. I could gouge an eye out. I'd still probably survive. But not very well. And that's what we're doing to the oceans. It's the life-support system of this planet. We've been dumping in it. We've been polluting it. We've been destroying it for decades. And we're essentially maiming ourselves.

Young people have, truly, the potential to change the world. Not when they get older - today.

The great news is that overwhelmingly far more than adults, youth already care about the environment. Young people are recognizing that we have largely made a mess of things with respect to the environment [and] that the burden to fix it will fall on them.
