Today people across the world are crying out for bold, big changes.

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. Here are seven more ideas that might 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 The UK officially banned the death penalty in 1998,²  but some right-wing politicians want it back. 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. Some believe this has created more inequality and fuelled climate change. To save the world we must  instead achieve degrowth: a gradual reduction of energy and resource use.

Character building. UK Prime Minister Rishi Sunak wants to bring back national service.³ The plan is that 18-year olds would be forced either to join the army or to perform community service, in order to achieve a "shared sense of purpose".

AI takeover. In April, the Cabinet Office expanded an AI trial. It aims to read government papers so that civil servants do not have to. Supporters claim this will make public services more efficient.

Age limit. Retired people are the most likely group to vote.⁴ Politicians often unfairly favour them. There should be a maximum voting age so that older people can make way for those who own the future.

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

All change! Tough times call for tough measures. 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.
