When I was a little girl you used to learn to sew all the holes in things, darning socks, but nobody mends things anymore.

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.

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.

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

There must be a reason why some people can afford to live well. They must have worked for it. I only feel angry when I see waste. When I see people throwing away things that we could use.

Let us not be too particular; it is better to have old secondhand diamonds than none at all.

I have been on the road and visited numerous places and met people from all over the globe. I can say that it looks nearly the same everywhere I have been: The climate crisis is ignored by people in charge, despite the science being crystal clear.

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.

Biofuels such as ethanol require enormous amounts of cropland and end up displacing either food crops or natural wilderness, neither of which is good.

The Apollo program certainly had no real commercial value. It was done for very different reasons and, I think, very good reasons for the time. It’s an extraordinary achievement of mankind, but it wasn’t sustainable.

More businesses should be following Apple’s stance in encouraging more investment in sustainability.

We cannot command Nature except by obeying her.

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

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

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.

We have to rethink our whole energy approach, which is hard to do because we’re so dependent on oil, not just for fuel but also plastic. If plastic vanished, there would be total chaos. We have to think quite carefully about using oil and its derivatives, because it’s not going to be around forever.

Innovations that are guided by smallholder farmers, adapted to local circumstances, and sustainable for the economy and environment will be necessary to ensure food security in the future.

By stopping flying, you don’t only reduce your own carbon footprint but also that sends a signal to other people around you that the climate crisis is a real thing and that helps push a political movement.

I mean, people aren’t continuing like this and not doing anything because they are evil, or because they don’t want to. We aren’t destroying the biosphere because we are selfish. We are doing it simply because we are unaware.

Obviously Tesla is about helping solve the consumption of energy in a sustainable manner, but you need the production of energy in a sustainable manner.

I’m frugal. I’m not a very acquisitive woman. I never waste food. If you prepare your own food, you engage with the world, it tastes alive. It tastes good.

An important priority for me is a business must get their own house in order. Be or become an agent of positive change in your own enterprise and adopt responsible practices to eliminate the risks that often lie at the root of inequality and poverty.

At Virgin, we have always backed the power of the entrepreneur and inventor to find solutions to tricky problems. Why should climate change and the battle against carbon be any different?

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.

Our population and our use of the finite resources of planet Earth are growing exponentially, along with our technical ability to change the environment for good or ill.

The situation the Earth is in today has been created by unmindful production and unmindful consumption. We consume to forget our worries and our anxieties. Tranquilising ourselves with over-consumption is not the way.

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.

The threat to the planet is us. It’s actually not a threat to the planet – it’s a threat to us.

We need enlightenment, not just individually but collectively, to save the planet. We need to awaken ourselves. We need to practice mindfulness if we want to have a future, if we want to save ourselves and the planet.

When we build, let us think that we build for ever.

We need to keep making our streets safer and our criminal justice system fairer – our homeland more secure, our world more peaceful and sustainable for the next generation.

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.

We must get rid of fossil fuels by developing injection systems for automobiles, which can run on bio-fuel.

The redwood is the glory of the Coast Range. It extends along the western slope, in a nearly continuous belt about ten miles wide, from beyond the Oregon boundary to the south of Santa Cruz, a distance of nearly four hundred miles, and in massive, sustained grandeur and closeness of growth surpasses all the other timber woods of the world.

I did this book ‚Harvest for Hope,‘ and I learned so much about food. And one thing I learned is that we have the guts not of a carnivore, but of an herbivore. Herbivore guts are very long because they have to get the last bit of nutrition out of leaves and things.

It is good to realize that if love and peace can prevail on earth, and if we can teach our children to honor nature’s gifts, the joys and beauties of the outdoors will be here forever.

The main thing that’s missing in energy is an incentive to create things that are zero-CO2-emitting and that have the right scale and reliability characteristics.

In the case of the environment, there’s no one to bail it out.

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.

Gain may be temporary and uncertain; but ever while you live, expense is constant and certain: and it is easier to build two chimneys than to keep one in fuel.

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

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.

Every other civilized nation in the world has been compelled to care for its forests, and so must we if waste and destruction are not to go on to the bitter end, leaving America as barren as Palestine or Spain.

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.

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.

As soon as a redwood is cut down or burned, it sends up a crowd of eager, hopeful shoots, which, if allowed to grow, would in a few decades attain a height of a hundred feet, and the strongest of them would finally become giants as great as the original tree.

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.

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

I’m glad to see that BMW is bringing an electric car to market. That’s cool.

There are thousands of ways to take action. For example, plant trees, pick up litter, join an organisation or movement that makes a difference and especially try to influence adults and put pressure on people in power.

I think there are more politicians in favor of electric cars than against. There are still some that are against, and I think the reasoning for that varies depending on the person, but in some cases, they just don’t believe in climate change – they think oil will last forever.

Any fool can destroy trees. They cannot run away; and if they could, they would still be destroyed – chased and hunted down as long as fun or a dollar could be got out of their bark hides, branching horns, or magnificent bole backbones.

People are going to buy cheap fertilizer so they can grow enough crops to feed themselves, which will be increasingly difficult with climate change.

I really wonder what gives us the right to wreck this poor planet of ours.

I have seen firsthand that agricultural science has enormous potential to increase the yields of small farmers and lift them out of hunger and poverty.

To shake your rump is to be environmentally aware.

Taking bold action on climate change simply makes good business sense. It’s also the right thing to do for people and the planet. Setting a net-zero GHG emissions target by 2050 will drive innovation, grow jobs, build prosperity, and secure a better world for what will soon be 9 billion people.

We should remember that there are nations which meet more than 30 to 60% of their power requirements through the nuclear power system.

I’m a radical environmentalist; I think the sooner we asphyxiate in our own filth, the better. The world will do better without us. Maybe some fuzzy animals will go with us, but there’ll be plenty of other animals, and they’ll be back.

I have a private plane. But I fly commercial when I go to environmental conferences.

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?
