Un barril de petróleo equivalía a 159 litros y se vendía en ese momento a unos 100 dólares, unas 600 coronas o unos 76 euros. Ese barril de petróleo suministraba por sí solo tanta energía...

The world has a very serious problem, my friend’ Shiva went on. ‘Poor children still die by their millions. Westerners and the global rich — like me — live in post-scarcity society, while a billion...

We need to focus every inch of our being on climate change, because if we fail to do so than all our achievements and progress have been for nothing and all that will remain of...

I believe that the only way that the human race is gonna survive is to start colonizing space and setting up colonies on the moon, and then space stations.

A foolish environmentalist wants to save nature from the greed of the market by exposing it to the tragedy of the commons. A smart environmentalist wants to save nature from the tragedy of the commons...

The Holy Land is everywhere

The eyes of all future generations are upon you. And if you choose to fail us, I say – we will never forgive you

Today we use 100 million barrels of oil every day. […] There are no rules to keep that oil in the ground. So we can’t save the world by playing by the rules. Because the...

My goal is to draw a line with some ‘flavor’ to it.

There are many paths leading to a garden and many experiences awaiting those who venture in. No matter what your motive—whether to grow healthy, delicious food; spend time outdoors feeling more alive than your desk...

I am here because I have to be here, as here I am supposed to be! All things should be, and usually are, found in their rightful places. Can you imagine how chaotic the world...

We have lots of unions who are planning to strike, so, I mean, adults striking from their work. And that is so incredibly important to show that this is such an — this is not...

The hole in the ozone layer is a kind of skywriting. At first it seemed to spell out our continuing complacency before a witch’s brew of deadly perils. But perhaps it really tells of a...

Wine is a gateway drug to environmentalism.

She leaned into me, and I could feel her hot breath against my ear. ‘I want you to eat me,’ she whispered. ‘I want you to eat me like you’re an angry Alaskan grizzly and...

Our house is on fire. I am here to say, our house is on fire. […] Adults keep saying: “We owe it to the young people to give them hope.” But I don’t want your...

Contrary to the ecologists, nature does not stand still and does not maintain the kind of equilibrium that guarantees the survival of any particular species – least of all the survival of her greatest and...

The test of a progressive policy is not private but public, not just rising income and consumption for individuals, but widening the opportunities and what Amartya Sen calls the ‘capabilities’ of all through collective action....

The idea of finding value in what people are willing to pay to get rid of it one of the fundamental backbones of ecocapitalism, as I think of it now.

We showed that we are united and that we, young people, are unstoppable.

They have taken the idea of nonharming, of gentleness toward the earth, to a very radical level. Even the weeds are not enemies.

What hurt him most of all, made him feel like a sick child aware of terrible wrongness and yet incapable of explaining it to anyone who might help, was that in spite of the evidence...

We risk losing what nature is if we couch its value in human terms.

We are facing an existential crisis… it will have a massive impact on our lives in the future, but also now, especially in vulnerable communities. And I think that we should wake up, and we...

Another glorious feature of many modern science museums is a movie theater showing IMAX or OMNIMAX films. In some cases the screen is ten stories tall and wraps around you. The Smithsonian’s National Air &...

Peace is a conscious choice.

I no longer follow the voices of the sane. I follow the ill because they see farther, feel much more and change what the sane will not. This is the paradox of philosophers—trying to understand...

Some people say that the climate crisis is something that we all have created. But that is just another convenient lie. Because if everyone is guilty then no one is to blame. And someone is...

Extinction, the irrevocable loss of a species, causes pain that can never find relief. It is an ache that will pass from generation to generation for the rest of human history.

Thank God men cannot fly, and lay waste the sky as well as the earth.

In looking at waste as an entirely modern, man-made idea, I stopped viewing garbage as garbage and instead slowly started to see it as a commodity.

We are striking because we have done our homework, and they have not.

I finally understood that I couldn’t avoid working to provide for myself, but that can also be a wonderfulthing, a beautiful thing.

Many conscientious environmentalists are repelled by the word “abundance,” automatically associating it with irresponsible consumerism and plundering of Earth’s resources. In the context of grassroots frustration, insensitive enthusing about the potential for energy abundance usually...

[T]his readiness to assume the guilt for the threats to our environment is deceptively reassuring: We like to be guilty since, if we are guilty, it all depends on us. We pull the strings of...

I have Asperger’s syndrome and that means I’m sometimes a bit different from the norm. And – given the right circumstances – being different is a superpower. It makes you think differently. And especially in...

I am pessimistic about the human race because it is too ingenious for its own good. Our approach to nature is to beat it into submission. We would stand a better chance of survival if...

The recognition that human beings are specifically and deliberately responsible for whatever aberrances farm animals may embody, that their discordances reflect our, not their, primary disruption of natural rhythms, and that we owe them more...

We have lived our lives by the assumption that what was good for us would be good for the world. We have been wrong. We must change our lives so that it will be possible...

I think it is insane that people are gathered here to talk about the climate and they arrive here in private jets.

I had fought on behalf of man against the sea, but I realised that it had become more urgent to fight on behalf of the sea against men.

Life on earth can never be fully understood. Life and all it holds is too big for humans to understand. There is the possibility for more joy than they ever comprehend and there is the...

We are the planet, fully as much as water, earth, fire and air are the planet, and if the planet survives, it will only be through heroism. Not occasional heroism, a remarkable instance of it...

Since our leaders are behaving like children, we will have to take the responsibility they should have taken long ago.

Sometimes just to touch the ground is enough for me, even if not a single thing grows from what I plant.

They keep saying that sea levels are rising an’ all this. It’s nowt to do with the icebergs melting, it’s because there’s too many fish in it. Get rid of some of the fish and...

I don’t think I understand that,” Meg insisted. “How can you lust yourself into oblivion. “”Oh, easily,” Ekaterina answered. “The lust is for things, possessions. The weapon turns on the nature of possessions, the fact...

That happens all the time. That’s basically all I hear. The most common criticism I get is that I’m being manipulated and you shouldn’t use children in political ways, because that is abuse, and I...

Only people with full stomachs become environmentalists.

I have been impressed by the realization that a few men have virtually ‘decided’ what experiences count and even exist in the world. The language of Western science–the reigning construct of male hegemony–precludes the ability...
