In our time of climate crisis war and economic uncertainty, people across the world are crying out for big, bold changes.

Dozens of campaign groups and activists seek to push their ideas into the political agenda. And, as Britain moves towards a general election, its politicians are looking for ideas to win votes.

This week The Day has examined three of today's biggest ideas: the 15-hour working week, Universal Basic IncomeThe concept of a government scheme in which every adult citizen receives a set amount of money regularly, without having to work for it. The aim of a basic income system is to alleviate poverty and enable people to find more meaningful work., and a world without borders.

These are far from the only big ideas floating around though, and here we look at seven further ideas that might yet shape the world to come.

Bring back executions. Today, 55 countries in the world have the death penaltyAlthough Barrett has said that, as a Christian, she would not order the death penalty, she has not actually opposed it..¹ Banned officially in the UK in 1998², some right-wing politicians want to bring it back, as they think it will deter would-be criminals, as well as reducing prisoner numbers.

Votes for youths. In Britain, 16-year olds can learn to drive, get married and work. And yet they are not allowed to vote, even though today's political decisions will affect their future. Some think they deserve the power.

Scaling back. Many countries chase economic growth. But some think this has created more inequality and fuelled climate change. To save the world we must instead achieve degrowth: a gradual reduction in energy and resource use.

Character building. Last month, UK Prime Minister Rishi Sunak claimed he would bring back national service,³ that 18-year olds would be forced either to join the army or perform community service. Sunak says this will give youths a "shared sense of purpose".

AI takeover. In April, the Cabinet Office expanded an AI trial to read government papers, in place of civil servantsAnyone working in a government department. The civil service has long-standing traditions and strict codes of conduct that can make it a law unto itself.. Supporters claim this will make public services more efficient.

Age limit. In many Western countries, retired people make up a huge section of society and are the most likely age group to vote.⁴ Politicians often unfairly favour the elderly. There should be a maximum voting age so that older people can make way for those who own the future.

Dying well. Some people die after a long and painful illness. Campaigners support assisted dying: the right to choose to die peacefully rather than to live in suffering. Labour leader Sir Keir Starmer is "personally in favour" of this.⁵

Which would you vote for?

All change! Tough times call for tough measures. Humanity faces huge challenges. Our current course is not working. We need to try something different.

Humans are problem-solvers. Innovations have improved our lives, from the wheel to cooking, electricity to human rights. We should revive that spirit.

Hold steady... There is a reason these ideas are from the fringes. Although they might have some benefits, they also have dramatic costs that many people do not want to face. 

Look to history: many attempts at bold change have caused suffering, from Soviet communist purges to Liz Truss's disastrous budget.
