We will have to leave this planet, and we’re going to leave it, and it’s going to make this planet better.

In a very real sense, it will not be one man going to the moon it will be an entire nation. For all of us must work to put him there.

We cannot command Nature except by obeying her.

I was born in London in England in 1934. I went through, as a child, the horrors of World War II, through a time when food was rationed and we learned to be very careful, and we never had more to eat than what we needed to eat. There was no waste. Everything was used.

Let’s pray that the human race never escapes from Earth to spread its iniquity elsewhere.

Houston, Tranquillity Base here. The Eagle has landed.

If humanity doesn’t land on Mars in my lifetime, I would be very disappointed.

If a man walks in the woods for love of them half of each day, he is in danger of being regarded as a loafer. But if he spends his days as a speculator, shearing off those woods and making the earth bald before her time, he is deemed an industrious and enterprising citizen.

The world, we are told, was made especially for man – a presumption not supported by all the facts. A numerous class of men are painfully astonished whenever they find anything, living or dead, in all God’s universe, which they cannot eat or render in some way what they call useful to themselves.

Most emissions aren’t caused by individuals, they’re caused by corporations and states.

The universal utilization of water power and its long-distance transmission will supply every household with cheap power and will dispense with the necessity of burning fuel. The struggle for existence being lessened, there should be development along ideal rather than material lines.

We could have saved the Earth but we were too damned cheap.

It’s time to commit to finding the answer, to search for life beyond Earth. Mankind has a deep need to explore, to learn, to know. We also happen to be sociable creatures. It is important for us to know if we are alone in the dark.

I’ve been very passionate about renewable energy for many years, particularly solar energy and its capacity to bring abundant clean, sustainable energy to millions around the globe.

Sweden is not a green paradise, it has one of the biggest carbon footprints.

The important achievement of Apollo was demonstrating that humanity is not forever chained to this planet and our visions go rather further than that and our opportunities are unlimited.

The effects of climate change are real and must be acted on.

The environment is everything that isn’t me.

The reason we should do a carbon tax is because it’s the right thing to do. It’s economics 101, elementary stuff.

The pace of progress on Mars depends upon the pace of progress of SpaceX.

Even if the economy crashes, we will still burn oil.

It’s not as though we can keep burning coal in our power plants. Coal is a finite resource, too. We must find alternatives, and it’s a better idea to find alternatives sooner then wait until we run out of coal, and in the meantime, put God knows how many trillions of tons of CO2 that used to be buried underground into the atmosphere.

I personally have stopped flying. I have stopped eating meat and dairy.

We should all grow our own food and do our own waste processing, we really should.

Thanks to my mother, not a single cardboard box has found its way back into society. We receive gifts in boxes from stores that went out of business twenty years ago.

By the time we see that climate change is really bad, your ability to fix it is extremely limited… The carbon gets up there, but the heating effect is delayed. And then the effect of that heat on the species and ecosystem is delayed. That means that even when you turn virtuous, things are actually going to get worse for quite a while.

You’re never going to get the amount of CO2 emitted to go down unless you deal with the one magic metric, which is CO2 per kilowatt-hour.

The vision is to figure out how there can really be dynamic entrepreneurialism in space.

I know Elon, we’re very like minded in many ways. We’re not conceptual twins. One thing I want us to do is go to Mars, but for me it’s one thing. He’s singularly focused on that. I think motivation wise, for me I don’t find that Plan B idea motivating. I don’t want a plan B for Earth, I want Plan B to make sure Plan A works.

This is the moment when we must come together to save this planet. Let us resolve that we will not leave our children a world where the oceans rise and famine spreads and terrible storms devastate our lands.

I think we are at the dawn of a new era in commercial space exploration.

SpaceX is only 12 years old now. Between now and 2040, the company’s lifespan will have tripled. If we have linear improvement in technology, as opposed to logarithmic, then we should have a significant base on Mars, perhaps with thousands or tens of thousands of people.

Can you imagine what a different world we will live in when businesses do what’s right for the communities and the environment in everything they do?

Gardening is not a rational act.

The reality is gas prices should be much more expensive then they are because we’re not incorporating the true damage to the environment and the hidden costs of mining oil and transporting it to the U.S. Whenever you have an unpriced externality, you have a bit of a market failure, to the degree that eternality remains unpriced.

Climate change is a terrible problem, and it absolutely needs to be solved. It deserves to be a huge priority.

We’ve gotta reinvest in space travel. We should’ve never left the moon.

Two kids in their dorm room can’t start anything important in space today. That’s why I want to take the assets I have from Amazon and translate that into the heavy-lifting infrastructure that will allow the next generation to have dynamic entrepreneurialism in space, to build that transportation network.

If we’re going to have any chance of sending stuff to other star systems, we need to be laser-focused on becoming a multi-planet civilisation.

If we want to travel into the future, we just need to go fast. Really fast. And I think the only way we’re ever likely to do that is by going into space.

I just think people should invest in the world. Don’t invest in fashion, but invest in the world.

The main message we want to get out there is that climate change is caused by the rotten economic system.

You need to be in the position where it is the cost of the fuel that actually matters and not the cost of building the rocket in the first place.

I resigned from the Marine Corps and flying in 1974, even though I loved them both. I quit because I no longer wanted to fight for peace. Instead, I believe we can build a more sustainable peace by working for prosperity.

If you think in terms of a year, plant a seed; if in terms of ten years, plant trees; if in terms of 100 years, teach the people.

I talk to fashion designers and say I want some money to save the rainforest, and they say, ‚Oh, I agree with you completely Vivienne. Yes, climate change, it’s definitely happening,‘ but they don’t feel that they can do anything about it; they don’t even think ‚Well let’s stop it!‘

A diplomatic solution that puts significant and verifiable constraints on Iran’s nuclear program represents the best and most sustainable chance to ensure that America, Israel, the entire Middle East will never be menaced by a nuclear-armed Iran.

Perhaps one day I will go into space.

Why should man’s first flight to the moon be a matter of national competition? Why should the United States and the Soviet Union, in preparing for such expeditions, become involved in immense duplications of research, construction and expenditure?

The environmentalists say capitalism is killing our oceans, air, land, and forests. Capitalists argue that they provide food, fuel, and building materials for a growing world.

You should be attacking the carbon emissions, period, and whether it’s cap-and-trade or carbon tax or whatever, that’s the realm in which we should be playing.

There is a sufficiency in the world for man’s need but not for man’s greed.

I am always trying to find fabrics that are more friendly to the environment – working with Virgin Atlantic, they managed to research into this and find more eco fabrics.

I have a company, and I’ve got to think about that. I’m trying to do my best there, and that’s a much harder task. We recycle as much as possible, and we conserve. But I’ve always been one to save everything – I even walk up stairs on the very inside or the very outside to not wear out the tread.

A business that makes nothing but money is a poor business.

I would like to fly in space. Absolutely. That would be cool. I used to just do personally risky things, but now I’ve got kids and responsibilities, so I can’t be my own test pilot. That wouldn’t be a good idea. But I definitely want to fly as soon as it’s a sensible thing to do.

In the absence of sound oversight, responsible businesses are forced to compete against unscrupulous and underhanded businesses, who are unencumbered by any restrictions on activities that might harm the environment, or take advantage of middle-class families, or threaten to bring down the entire financial system.

It’s important that we attempt to extend life beyond Earth now. It is the first time in the four billion-year history of Earth that it’s been possible, and that window could be open for a long time – hopefully it is – or it could be open for a short time. We should err on the side of caution and do something now.

We should no longer measure our wealth and success in the graph that shows economic growth, but in the curve that shows the emissions of greenhouse gases.

That’s one small step for a man, one giant leap for mankind.

I think we have a good chance of surviving long enough to colonize the solar system.
