The passenger pigeon, the golden toad, the Caspian tiger: they are all gone, and other species hang by a thread. Our actions are not merely driving other species to extinction: we threaten our own survival, too, by destabilising ecosystems and destroying biodiversity.

But cutting the working week would free the individual, giving millions of workers more time to spend as they see fit. Human freedom should be the core aim of modern socialism. The right to work less would be an act of liberation - and a cause the left should embrace.

A sneer can often reveal far more about the sneerer than the object of their derision.

In the 1920s prohibition in the US notoriously failed to tackle alcohol use, led to lethal forms of liquor entering the black market, fuelled organised crime and its associated violence, and wasted public money.

Donald Trump's mini-me, Boris Johnson, is in the ascendant: the Tory crown is his to lose. But his colleagues know he's an incompetent, a man who cares only for himself, who was fired twice - by a newspaper editor and a party leader - over allegations of dishonesty.

Few would deny the importance of tackling online hatred or child abuse content. The internet, after all, has become a key weapon for those who disseminate and incite hatred and violence against minorities, and for those who pose a horrifying threat to children.

Socialism is the democratisation of every level of society, or it is nothing. It is based on an understanding that the concentration of wealth and power leaves democracy hollowed out, and that simply trooping to a polling station every few years is an insufficient counterweight to the behemoths of global capital.

Yet we have learned from the Scottish independence vote and with Brexit what referendums do to our politics. They foster bitter divisions in ways that parliamentary elections tend not to do.

So much of our lives is surrendered to subordinating ourselves to the needs and whims of others, turning human beings into cash cows rather than independent, well-rounded individuals.

Humans should be the Earth's custodians, not its butchers. Much attention - though not enough - focuses on the existential threat posed by climate change. But humanity's mass destruction of the Earth's wildlife is all too little discussed.

Opposition to immigration is an emotional argument, and human beings are emotional, not robots powered by data.

If only Brexit would go away. It sucks the political oxygen away from the issues we should all be discussing: like low wages, insecure jobs and the housing crisis.

For the well-heeled elites, the 90s and 00s were a non-stop party with no hangover: even after the financial crash, the fortunes of Britain's 1,000 richest families more than doubled.

In the 1980s, the trade unions suffered a series of calamitous setbacks. Mass unemployment terrified workers into not risking the wrath of bosses. Repressive anti-union laws stunted the ability of workers to organise and defend their rights.

We should all expect to be able to die with comfort, dignity and love. Our society does not lack the wealth to realise this aspiration, but the willpower.

Austerity and economic insecurity have collided with the scapegoating of migrants and refugees, at a time when global instability and warfare have driven millions to flee violence and persecution, a minority of whom have arrived on European shores to be met with hostility.

Freedom of movement in Europe has been all but abandoned as a cause in British politics. Brexit was far more about freedom of movement than our exact trading relationship with the EU, and the electorate rejected it.

Genuine democracy is frequently messy, not stage-managed.

Grief is like wandering through a minefield, as my mother puts it: however carefully you tread, a sudden detonation can happen out of nowhere. A song played in a supermarket; an overheard phrase; someone in the distance who your mind cruelly suggests is your loved one for a fleeting moment.

A party committed to defending the economic interests of rich elites could never win by saying so.

Tuition fees have formed part of a full-frontal assault on the living standards of a generation battered by a housing crisis, stagnating wages and slashed services.

In the hyper-exploitative sector of retail and hospitality, workers are made to feel worthless - undeserving of a proper wage and genuine security.

For decades, life expectancy steadily rose in Britain: and then, suddenly, just as the Tories took power and imposed austerity, this improvement ground to a halt.

Britain in 2018 has the feel of a Netflix drama approaching its season finale. It's the classic 'how on earth does anyone get out of this one?' kind of cliffhanger, with all of the key protagonists confronted by their nemesis.

For years, media moguls and campaigns bankrolled by the rich have fed the lie that migrants are the cause of injustices propagated by the powerful: the failure to build housing, the strain on public services by cuts, the lack of secure jobs, the decline in real wages.

A flourishing, diverse media is essential to a functioning democracy.

The 'free market' is a creed that stirs up near religious devotion among its believers. It is in fact a con, a myth, a great deception.

A huge portion of our lives involves the surrender of our freedom and personal autonomy. It is time in which we are directed by the needs and whims of others, and denied the right to make our own choices.

We need to organise unapologetically anti-racist campaigns in our communities, ones that emphasise the fact that the blame for social ills lies with the powerful.

The vast majority of people back higher taxes on the rich. Yet these are fringe ideas within most of the mainstream media, which marginalises those who support them.

Yes, we need action to deal with online hatred and abuse. But let's make sure there are clear safeguards, or history will repeat itself, and peaceful opponents of an unjust status quo will suffer the consequences.

Philanthropists decide how to spend their money based on their own personal whims, rather than what is best for the social good.

Nonbelievers may welcome the collapse in British religiosity, but the decline in church attendance has meant that the chance to chat each week with other people has vanished.

Jobs have become more precarious and staff turnover has increased while union membership has plummeted, weakening workplace solidarity.

Poverty damages the educational potential of children, whether through stress or poor diet, while overcrowded, poor-quality housing has the same impact too.

University should foster imagination and creativity, enriching society in the process.

The bereaved are often treated badly. There is no statutory paid bereavement leave, with the emotionally stunned often compelled to work within days of losing a loved one.

Although economic grievances were critical in delivering the referendum result, Brexit has fomented an all-out culture war.

Everyone is entitled to change their mind when the facts do.

Who can begrudge the generosity of the wealthy, you might say. Wherever you stand on the concentration of wealth and power in the hands of a tiny global elite, surely such charity should be applauded? But philanthropy is a dangerous substitution for progressive taxation.

When those with wealth and power fear that their privilege is even mildly challenged, they invariably clothe themselves in the garbs of victimhood.

The existence of billionaires should sound an alarm: they are the most extreme manifestation of wealth generated by the efforts of millions of people being funnelled into the pockets of a tiny few.

From a genuine living wage to a mass housebuilding programme and strong workers' and trade unions rights preventing a race to the bottom, our answers to the grievances that help drive anti-immigrant sentiment must be front and centre.

We are unlikely to spend our last moments regretting that we didn't spend enough of our lives chained to a desk. We may instead find ourselves rueing the time we didn't spend watching our children grow, or with our loved ones, or travelling, or on the cultural or leisure pursuits that bring us happiness.

If you are dim but have rich parents, a life of comfort, affluence and power is almost inevitable - while the bright but poor are systematically robbed of their potential.

If you've never lived outside London, and if you've always had a car, it's difficult to understand how dire bus services undermine your standard of living: from being able to get to work, meet friends in the pub, get the weekly shop or take the kids on a day out.

Thousands do benefit from love, support and comfort in their final chapter: I watched my dad slip away without pain as Bob Dylan and Bruce Springsteen tracks played in a warm Marie Curie hospice, surrounded by doting nurses and his family.

If you live in London, where politicians and media commentators spend most of their time, you are spoilt for transport choices - trains, an extensive underground network and a regular bus service.

From a very young age, boys are taught that real men get into fights, say demeaning things about girls and women, show extraordinary athletic prowess, avoid looking studious, don't do anything to display supposed emotional 'weakness' and prioritise competition over cooperation.

The age of mass politics is one that demands radical solutions rather than tinkering.
