I suppose my biggest concern would be if the planet is going to be in good enough shape for the next generation to have the privileges that we've had.
The images of Earth's delicate biosphere, contrasting with the sterile moonscape where the astronauts left their footsteps, have become iconic for environmentalists: these may indeed be the Apollo programme's most enduring legacy.
Our connection to nature grounds us, it makes us more spiritually aware. We must keep the legacy of nature materially alive for future generations.
She was green when green wasn't in. From sea to shining sea, Lady Bird Johnson has left her legacy in a more beautiful America. From millions of trees and wildflowers planted, to interstates free from billboards and replaced with green.
My heart found its home long ago in the beauty, mystery, order and disorder of the flowering earth. I wanted future generations to be able to savor what I had all my life.
It's all very brilliant to build bridges and buildings, but long after we're gone, it will be the natural things in this world which will still be here.
Of all the waste we generate, plastic bags are perhaps the greatest symbol of our throwaway society. They are used, then forgotten, and they leave a terrible legacy.
I have planted over 6,000 trees at home in Scotland, some of them oak. I'd like my children to be able to watch them grow.
What I'm concerned with is what I would call the missing history - the invisible imprint of our stay on Earth and in time.
This land, this water, this air, this planet - this is our legacy to our young.
There are a lot of people who want to leave their children with a world that is in better shape.
This isn't just about today, this about generations to come. And you've got a chance to be the greatest conservation President since Theodore Roosevelt, and I think he's done it.
Each generation takes the earth as trustees. We ought to bequeath to posterity as many forests and orchards as we have exhausted and consumed.
I have two grandchildren. I want to hand them a planet and community that is really thriving.
Someday, our children, and our children’s children, will look at us in the eye and they'll ask us, did we do all that we could when we had the chance to deal with this problem and leave them a cleaner, safer, more stable world?
I can't think of anything more important than the environment we leave to our children and our children's children.
The earth shall be left to no one.
I consider myself responsible to the coming generations, which are left stranded in a blitzed world, unaware of the soul trembling in awe before the mystery of life.
