Through the rest of this century, the world is facing a number of seemingly insurmountable problems – problems for which there appear to be no easy answers. Some so complex and so threatening that they could doom humanity for all eternity. Yet, even for those challenges, there are answers if we are willing to acknowledge the problems and make the changes so urgently required.

Here they are in ascending order of difficulty:

Rise of Authoritarianism – The solution for this one is exceedingly simple: Vote! Vote only for those politicians who are committed to democracy. Fight tyranny at every turn. No politician who embraces discrimination of any kind belongs in office.

Corporate Consolidation – The phenomenon of too-big-to-fail banks and multinational corporations has led to a wide variety of problems for humanity. These include a lack of competition leading to inflation, the elimination of pension funds for workers, the growing disparity of income between CEOs and workers, the exporting of jobs in the search for ever cheaper and more compliant labor…the list is long.

Fortunately, the solution is also simple. Indeed, Congress gave us a seldom-used tool to break up these industrial cabals and growing monopolies: The Sherman Antitrust Act of 1890. It’s time our government used it.

Wealth Disparity – Globally, the richest 10% of the global population currently take home 52% of the income. Those in the poorest half of the global population earn just 8%.

In the U.S., the wealthiest one percent of Americans hold more than 32 percent of the nation’s wealth. The top 10 percent hold 77 percent of the wealth, while the bottom 50 percent of households hold just one percent of the wealth. And 7.5 percent of the population has a negative net worth – meaning they are in debt.

By race, white households hold more than 86 percent of the wealth while black and Latino households hold less than 3 percent of the wealth.

And, until the election of President Biden the problem has only gotten worse, a result of the vicious economic policy called Trickle-Down Theory that was embraced by Ronald Reagan and every Republican president since. The subsequent wealth gap has led to growing poverty and food insecurity, unfair tax policies, a government that is bought and paid for by wealthy individuals and corporations, and a loss of tax revenue that has led to a growing national debt.

Yet there is some glimmer of hope for those at the bottom of the wealth scale. According to the Federal Reserve, the average wealth of the bottom half of Americans has increased by 80 percent since 2019, perhaps as a result of President Biden’s policies. (Of course, wealth growth is statistically much more profound if you have very little wealth to begin with.)

The solutions to wealth disparity also seem relatively simple: Enact a wealth tax and impose strict limits on donations to political campaigns. That could give all Americans a chance at the equal representation our Founders intended.

Gun Violence – The U.S. suffers approximately 20,000 violent gun deaths each year (not including suicides) and more than 35,000 gun injuries. Thanks to the NRA, other so-called gun rights groups, and gun manufacturers, police have to assume that every person they encounter is armed. Our schools and many public buildings have become virtual fortresses in an attempt to prevent mass shootings. And, from the age of 5, children are taught to live in fear of active shooters. No other developed nation in the world experiences these problems. But our gun manufacturers are trying to change that by exporting guns to criminal gangs worldwide.

It doesn’t have to be this way!

The solution is to follow Australia’s lead by banning and collecting guns, especially semi-automatics. Instead, as exemplified by the recent Supreme Court decision overturning the ban on bump stocks, the U.S. is headed in the opposite direction.

Climate Crisis – The U.S. has long led the world in the amount of fossil fuels burned per capita. And now we are the world’s largest producer of oil and natural gas. For more than 50 years, scientists have been warning us that, by incinerating fossil fuels, we are in danger of incinerating our planet. Unwilling to believe them, we have protected our fossil fuel industry and refused to modify our unsustainable lifestyle.

Sure, we have made some limited progress by recycling, better insulating our homes, producing more energy efficient appliances, and expanding the use of renewable fuels. But those measures are far too little, too late.

We led the world in establishing an extravagant, disposable culture. Now we need to lead the world to live within our planet’s means. Change is possible. But we must hurry. As you can see by the ever-increasing, ever more violent storms and other climate-related disasters, time is running out, and quickly.

Mass Migration – In recent years, migrants have flooded the borders of the United States and other highly developed nations. As a result of wars, violent gangs, autocratic rulers, and natural disasters such as drought, storms, and flooding, millions of people are faced with the choice of either migrating or dying.

Think immigrants are ruining your country? Then demand that our politicians do something to improve circumstances in their home countries. And be willing to open your hearts as well as your pocketbooks to help.

Mass Extinctions – In Earth’s history, there have been 5 mass extinctions defined as the loss of 75 percent of all species within a relatively short period of time. Scientists tell us that we are about to experience a sixth mass extinction as the result of human activities such as deforestation, unsustainable food production, pollution, encroachment of habitat, and the burning of fossil fuels.

Currently, extinction of species is occurring 1,000 to 10,000 times more rapidly than the natural rate. Why should we care?

First, we are living in an ecosystem. The life of one species depends on the life of others. Second, the world will become a much less interesting and livable place without some of the most vulnerable species. And third, we’re one of the species that could go extinct!

You already know the ways to mitigate the sixth mass extinction: Stop wasting resources, limit the use of fossil fuels, limit travel, stop polluting, and quickly transition to a mostly plant-based diet.

We have been the problem. Now we must become the solution.

Artificial Intelligence – AI could be the answer to many of our problems. Or, it could add to them. It simply depends on how we use it.

Used properly, AI can help us eradicate diseases, streamline research, create solutions for complex problems, perform the most dangerous and boring jobs, and help us to objectively solve conflicts.

AI-driven vehicles could make our roads safer and more orderly. AI could make logistics more efficient and more predictable. The possibilities are endless.

But there’s a much darker side to AI.

AI is already creating deepfakes – fake videos and images of people saying and doing things they never intended or even imagined. Women have been victimized by fake images of them nude or engaging in sex acts. Even worse, deepfakes of political candidates and leaders could have profound consequences.

AI could eliminate millions of jobs making humans essentially obsolete.

Not surprisingly, AI has been embraced by the military to replace humans in battle. Future armies, navies and air forces could be dominated by AI-controlled robots making real-time decisions of life and death. Once that happens, will we become the predominate targets?

One AI researcher believes so. He estimates there’s a 99.9% chance that AGI (Artificial General Intelligence) will lead to human extinction within the next 100 years claiming that no AGI model he has seen has been safe. And though other AI researchers are less certain that AGI will lead to our extinction, they are not particularly reassuring.

A Final Word: As daunting as some of these challenges seem, to some degree, they all can be addressed with one simple action: Vote! We must climb out of our media silos, ignore the misinformation and disinformation peddled by the moneyed interests, educate ourselves, and vote for the politicians who are willing to acknowledge the scope of the challenges and attack them in earnest.
