The point about Roosevelt's New Deal was that it was visionary - for the 1930s.

With pollution from traffic a major source of greenhouse gas emissions, we should be building a transport and planning system that makes car-free travel for shorter distances the norm for the majority.

Coronavirus has exposed for all what many of us already knew - some of our most important workers have barely enough to live on, and millions are condemned to financial insecurity, inequality and food poverty.

Other countries are developing well-being economies - we should do the same. That is the way to create a society which would stand the test of time - for everyone.

Humanity's inclination to be kind during the coronavirus crisis is an unprecedented, uplifting demonstration of solidarity.

The truth is that goodness is hardwired in humanity.

There is an important message that all political leaders should be taking from the response to coronavirus, and that is that people are prepared to make hard choices for the common good.

No more top-down politics with Westminster dictating what's right for every community. We must all be partners in designing a better future for our country.

Sometimes it takes a sudden change to make you realise just how bad things were.

Clear skies and clean air must become the new normal. We must re-design our cities, reclaiming the streets for cycling and walking, allowing people to walk along streets unpolluted by traffic.

We must not let the response to the coronavirus crisis make the climate and inequality crises even worse.

When this coronavirus crisis is over, what kind of society will we be? A more important question is what kind of society do we want to be?

It used to be said that war was the locomotive of history, with its power to accelerate change. The coronavirus crisis has that same power. It has already shown us who we really are, and how there is much more than unites than divides us. It has shown how governments need to work with their citizens to overcome threats or challenges.

The response to coronavirus has shown what can be done when governments put their mind to it.

Huge public spending and borrowing in the face of an existential crisis is clearly the right thing to do, as is putting people's health and wellbeing above the pursuit of economic growth.

Addressing the climate and biodiversity crises requires us to radically change our economic models, moving away from economic growth as the over-riding measure of progress and moving instead towards improving health and wellbeing for people and nature. That means a different economic model taking us towards a sustainable economy.

Once upon a time the Conservative party was a broad church which embraced a range of views.

We always knew that whatever party Nigel Farage led - first UKIP and then the Brexit party - was basically a vehicle for his own political self-glorification and now he's proved it.

If a prime minister can suspend parliament to deliver a 'no deal' Brexit, what will the government try to do next with no democratic scrutiny or oversight?

We promote new fossil fuel infrastructure, from airport expansion and coal mines in the U.K. to oil pipelines in the U.S. Investments are meant to build and secure our shared future - but all these fossil fuel investments are directly fuelling the climate crisis that threatens to undermine that future.

Actions speak louder than Climate Emergency declarations.

Many are outspoken about the climate crisis, but conveniently ignore the fact that support for fossil fuels is not just incompatible with curbing emissions but dangerously counterproductive.

We can no longer allow special corporate interests to shape our political and financial decisions, while our citizens and communities cry for real climate action.

Nuclear weapons remain a costly distraction from the real security threats we face, like climate change.

The billions being spent on Trident replacement would be much better spent on investing in developing the infrastructure we need for a zero-carbon economy, as well as in protecting public services. To use the money on a project that makes Britain and the world a far more dangerous place is politically irresponsible and economically obscene.

If we genuinely believe in a bigger future for our country, we have to redistribute both wealth and power - so people can take back control for good, not just for one vote.

We should entrust our young people with a voice to express their views on what their futures should look like.

We must instil our future leaders with the expertise, knowledge and skills to prevent climate breakdown and restore nature to health.

Everything from the infrastructure we build to the products we use must now be aimed squarely at building a zero-carbon world.

Banks and investors have poured money into dirty energy and high-carbon for decades. While no single policy is a magic bullet for the climate crisis, there is also no way of solving it that doesn't involve a fundamental reimagining of the role of our financial system.

We know that Brexit would make our poorest communities poorer still. That it would make the powerless even less able to effect change.

Our economy is failing far too many - forcing parents to use foodbanks to feed their children, demonising migrants and condemning all of us to climate breakdown.

Labour needs to end its support for expensive nuclear power and vanity projects like HS2, and take a firm stance against the ecologically impossible expansion of airports.

The Government needs to recognise that we live on a planet with finite resources - and start measuring our progress as a society by the quality of our lives, not the expansion of our GDP.

It's going to take everyone to rebuild a fairer, more sustainable, more beautiful Britain.

The people who serve your fast food lunch or your after-work drinks deserve dignity - and if big companies don't start paying them enough for a decent standard of living, they have the power to close these businesses. But no one goes on strike lightly.

Continuing down a path where profit is king is unsustainable for our society, our health and our planet.

As more and more people demand fair pay, the Government and big corporations are going to have to take notice.

I stand alongside everyone campaigning for better pay and conditions - they are paving the way for a fairer society.

When threats become unspeakable, unshareable and even unreadable, their power over us only grows.

For expectant mothers there's so much to think about - and so much to prepare for. In amongst those many thoughts and all the excitement are also some concerns, not least the serious worries for many about what will happen at work.

We need to block dirty diesels getting public money - no question there.

Fading are the days in which a cohort of towering power stations ran the game (and captured all the profits).

What does the public want? It wants a vested interest in its own energy provision - driving more efficient behaviour. It wants greater choice and responsibility at a local level. And it wants increased use of renewables to protect the environment.

A girl named Rachel transformed my childhood. Life was safe, suburban and comfortable, but ours was a home without books. I met her aged 11, and she introduced me to the joys of poetry and literature. It opened my mind to ideas I could never have dreamed of.

Petra Kelly is my inspiration, one of the founders of the German Greens.

Being an MP for a place you love is an extraordinary gift.

I've been arrested a few times. The most high-profile instance was when protesting at the fracking site in Balcombe. It's an industry which will undermine our chances of tackling climate change.

Trump is surrounding himself with so many climate sceptics and when he himself says he thinks climate change is a Chinese hoax then there are real concerns.

To the extent that Bernie Sanders was about building a movement of people where challenging things that up until then were unchallengeable, then absolutely we want to be seen in that mould.
