“If we continue to think of ourselves mostly as consumers, it’s going to be very hard to bring our environmental troubles under control. But it’s also going to be very hard to live the rounded and joyful lives that could be ours. This is a subversive volume in all the best ways!”

There is a tendency at every important but difficult crossroad to pretend that it’s not really there.

We spend a lot of time playing defence against bad things. So, in the US, one of the focusses has been this huge Keystone Pipeline project, another has been the coal ports on the Pacific Ocean.

Look – every time is the wrong time and the perfect time to have a kid, and you just do it when you can.

The laws of Congress and the laws of physics have grown increasingly divergent, and the laws of physics are not likely to yield.

I don’t spend a huge amount of time fixated on climate denial because I don’t think that their objections, though sometimes couched in science, are based in science. I think they’re based in ideology. And I don’t think there’s anything you can do.

We’d like to get the fossil fuel industry on the back foot for a while, having to deal with us.

The idea that China and India will just abandon climate action is not true, because they’re doing it for more reasons than we are.

Very few people on earth ever get to say: ‘I am doing, right now, the most important thing I could possibly be doing.’ If you’ll join this fight that’s what you’ll get to say

I did very much like [Barack] Obama’s attack on fossil fuel subsidies for fossil fuel companies. We asked for that in demonstrations and petitions, and now we’ll try to push it forward.

No one is strong enough – given the magnitude of the task, everyone has to step up their game.

I’m guessing the most efficient way would be to transfer an awful lot of technology, but also direct aid to deal with climate emergencies already underway. Hillary [Clinton] has already said $100 billion a year would be appropriate.

To me the analogy [to climate change] is… doctors worry a lot about cholesterol. And if you go to the doctor, and the doctor says “oh, your life would be happier if you ate a different diet and exercised” people pay no attention.

The Arctic and the Antarctic are melting quickly. We may have waited too long to get started. But this is a day for optimism because the battle is fully joined, and the idea that big oil is unbeatable is no longer true.

I think that it is impossible to think of a threat to social justice greater than what we are doing to the earth’s atmosphere at the moment.

It now appears that the fracturing of that ice is happening much more quickly than people previously thought, apparently at a slow melt.

According to new research emerging from many quarters that our continued devotion to growth above all is, on balance, making our lives worse, both collectively and individually

We are in an environmental crisis which threatens the survival of this nation, and of the world as a suitable place of human habitation.

I’m such an advocate for animal rights and environmental rights.

The environmental crisis is a sign that the ecosphere is now so heavily strained that its continued stability is threatened. It is a warning that we must discover the source of this suicidal drive and master it before it destroys the environment-and ourselves.

I am passionate about exploring the confluence of environmental and human health. I believe that the goals of conservation must constantly revisit a stated purpose.

We have forgotten how to be good guests, how to walk lightly on the earth as its other creatures do.

Finally, since human beings are uniquely capable of producing materials not found in nature, environmental degradation may be due to the resultant intrusion into an ecosystem of a substance wholly foreign to it.

The environmental crisis is a global problem, and only global action will resolve it.

When you fully understand the situation, it is worse than you think.
