Planetary Limits Quotes

We’re turning everything on the planet into food for humans so we’re cutting down the rainforests, displacing all of the animals, and we’re doing all this to feed humans... ... Imagine if there were only 2 billion people polluting? We’re already overpopulated. I feel we’ve become a parasite on this planet. If this population keeps growing, we’ll just keep devouring the planet, and I don’t think it’s going to stand for that very long.

Regardless of what we consume, the sheer volume of consumption is overwhelming the Earth's living systems.

I think the human race doesn't have a future if we don't go into space. We need to expand our horizons beyond planet Earth if we are to have a long-term future. We cannot remain looking inward at ourselves on a small and increasingly polluted and overcrowded planet. We need to look outward to the wider universe.

Since the mid-1970s, people have been consuming more resources than the planet’s natural capital can replenish.

A planet is the cradle of mind, but one cannot live in a cradle forever.

I realized up there that our planet is not infinite. It's fragile. That may not be obvious to a lot of folks, and it's tough that people are fighting each other here on Earth instead of trying to get together and live on this planet. We look pretty vulnerable in the darkness of space.

We've moved from a small world on a big planet to a big world on a small planet.

If everybody on the planet today had the same standard of living as the average European or American, we would need three new planets. But we don't even have one new planet. We have this one, and with the way we're polluting it, the shrinking water resources, the climate change, the experimentation with plants... the outlook is grim.

The fact that a cloud from a minor volcanic eruption in Iceland—a small disturbance in the complex mechanism of life on the Earth—can bring to a standstill the aerial traffic over an entire continent is a reminder of how, with all its power to transform nature, humankind remains just another species on the planet Earth.

The metaphor is so obvious. Easter Island isolated in the Pacific Ocean — once the island got into trouble, there was no way they could get free. There was no other people from whom they could get help. In the same way that we on Planet Earth, if we ruin our own [world], we won't be able to get help.

I believe we have these capabilities. It doesn't mean that we will use them. Our future is not assured here. It's not clear that we will survive our own folly, but we have a rare opportunity to do that if we listen and see the messages that nature is showing at us right now, that the finiteness of our own resources and our own planet are showing us right now.

We're not going to persuade people in the developing world to go without, but neither can we afford a planet on which everyone lives like an American. Billions more people living in suburbs and driving SUVs to shopping malls is a recipe for planetary suicide. We can't even afford to continue that way of life ourselves.

The planet should not be used as a warehouse of resources to serve humanity's selfishness

Well, capitalism is a big problem, because with capitalism you're just going to keep buying and selling things until there's nothing else to buy and sell, which means gobbling up the planet.

Earth was not built to serve the needs of humans.

I don't totally buy or believe the paradigm that's constantly presented to us and the financial news is obsessed with, which is growth. There seems to be this paradigm which is: There has to be growth. I'm watching it and thinking, am I the only one who recognises this is a small planet isolated in a gigantic universe? Where are we growing to?

We live in this culture of endless extraction and disposal: extraction from the earth, extraction from people's bodies, from communities, as if there's no limit, as if there's no consequence to how we're taking and disposing, and as if it can go on endlessly. We are reaching the breaking point on multiple levels. Communities are breaking, the planet is breaking, people's bodies are breaking. We are taking too much.

The way I see it, the earth is going to be here after we're dead and gone. Even if it's a polluted planet, and they messed it up. Where do they go from here - to another planet so they can mess that up too?

The planet is full and we will be rubbing shoulders forever. There is nowhere else to go.

One can see from space how the human race has changed the Earth. Nearly all of the available land has been cleared of forest and is now used for agriculture or urban development. The polar icecaps are shrinking and the desert areas are increasing. At night, the Earth is no longer dark, but large areas are lit up. All of this is evidence that human exploitation of the planet is reaching a critical limit. But human demands and expectations are ever-increasing. We cannot continue to pollute the atmosphere, poison the ocean and exhaust the land. There isn't any more available.

In pragmatic terms, our challenge is less to save the earth from ourselves and more to save ourselves from an earth that, if pushed too far, has ample power to rock, burn, and shake us off completely.
