While most of the earth’s surface is covered in water, there are ever increasing water shortages. One cause is obvious: the human population is increasing and the same amount of water is being spread among an increasing number of people. So, there is less water per person as our population increases.
Water is also being used in more ways than before, and industrializing countries have increased their water use. To illustrate, AI, manufacturing and agriculture use massive amounts of water, often in places that are ill-suited to such activity. In some cases, water can be reclaimed and re-used, but not always.
It is not just the amount of water that matters, but what it can be safely used for. As we contaminate water, we decrease the usable water supply. In some cases, we transform it from a resource to a waste that must be sealed away. Industrial chemicals, fertilizers, and even radioactivity are examples of water contaminants. Fracking, for example, contaminates water—even when it is done properly. While contaminated water can sometimes be re-used, it is usually unfit for human consumption. While it can be argued that contamination is limited and the amount of water vast (“the solution to pollution is dilution”), the earth’s water is obviously still finite. That means that as water is contaminated, the amount of usable water is reduced. If this goes on long enough and the water is not decontaminated, the effects will be significant. While worldwide contamination is of concern, what matters to most people is not the total available water, but what is available to them. In addition to contamination, there is also the impact of climate.
While some deny climate change or the role of humans in the process, it is well-established historical fact that the climate does change and the ruins of ancient cities attest to this. In these cases, it is the location of water that matters and shifts in climate (whatever the cause) can create zones of shortage. This is happening today, just as it happened in the past. While the total water on the earth is not really impacted by climate change, the location and quality of the water is affected. For example, while drought in one area does not mean that the earth has less overall water, it does mean that the people living there have less water. Climate change can also cause contamination. For example, my adopted state of Florida is plagued by blooms of toxic algae which might be impacted by the changing climate. While some might taunt those concerned with this for being lake huggers, these outbreaks impact what matters most to the “practical folk”, namely money. Florida, after all, generates revenue from tourism and few want to travel to look at green slime. There is also the concern with the water supply as green slime is not safe to drink. While it is possible to continue the litany of water worries, the above should suffice to show that water shortages are a concern. This raises the question of how to deal with the problem.
Environmentalists have been arguing for years that the solution is to reduce pollution and address climate change. While a reduction of pollution has been a general trend in the United States (thanks in part to Richard Nixon creating the EPA), the current political environment favors an increase in pollution and a decrease in regulation. The moral value behind this view is that environmental costs should be shifted from those who profit from causing damage to those impacted by the damage. For example, rolling back regulations on what companies can dump into the water reduces their costs, but imposes health costs on those who drink contaminated water. The principle of fairness would seem to require that those who make the profit also pay the cost, but politicians are very selective in their concerns about fairness. Because of the current political climate, we should expect an increase in water contamination.
One controversial solution is to recycle waste water, especially sewage, so that it can be used as potable water. While recycling always involves some loss, this would allow cities to address water shortages by reusing their water. It would also have environmental benefits, if the waste was dealt with properly (and, interestingly, sewerage can provide valuable raw materials).
One major obstacle is the cost as recycling water for human consumption requires infrastructure. However, this cost can be worth it in the face of water shortages. It is, after all, probably cheaper and more convenient to recycle water than to transport water (and that water must obviously come from somewhere).
Another major obstacle is psychological. Many people find the idea of drinking water that was recycled from sewage distasteful, even if the recycled water is cleaner than the water they currently consume. To be fair, there are real concerns about ensuring the water is properly treated and improperly recycled sewage could contain harmful microbes or chemicals. But these are problems that can (and have) been addressed so that recycled sewage is no riskier than a conventional water supply (and perhaps less so in many places).
Even when people accept treated water as safe, the distaste problem remains because some think that drinking water that was recently sewage is gross, even though the water is pure and safe to drink. As such, simply proving it is safe will not solve this psychological problem.
This is analogous to proposals to use processed insects as a food source. Even if the food is indistinguishable from “normal” food, clean, healthy and nutritious, many people think this is gross. This includes people who regularly devour parts of animal corpses (better known as “meat”)
Since this is a problem of feeling rather than reason, the solution would need to focus on changing how people feel about recycled water so they can reason about it. One possible approach is by telling the story of water in general. With a little reflection, people understand that tap water has been recycled countless times. Any water you recently drank was most likely filtered through the kidneys of many creatures over the millennia and probably passed through many humans. It might have even passed through you at one point. As such, all the water we consume is recycled already and was almost certainly disgusting (vulture vomit, for example) at one point. However, the process of cleaning it, , cleans it: the water is then fine to drink. As such, if a person is willing to drink any water, then they should also be willing to drink properly recycled water. Water that was just recycled properly from sewage is no more disgusting than water that was once part of vulture vomit and is now in your coffee or bottled water.
People can still say that it is proximity that matters. Recycled water was just recently sewage, but their bottled water or coffee has (probably) not been vulture vomit for a long time. From a rational standpoint this difference should be irrelevant: clean water is clean water, regardless of how long it has been clean. Unless one believes in some sort of mystical or metaphysical contamination that is undetectable by empirical means, then the rejection of safe recycled water would be unfounded. However, unfounded and irrational beliefs drive much of politics and human decision making in general, so the practical challenge is to influence people to not be disgusted by recycled water. Some might be won over by other feelings, such as positive feelings about the environment or the survival instinct (recycled water is preferable to no water). Hard core campers and hikers, who have sucked up bog water through a filtration straw, might be the easiest people to win over. But such psychological manipulation goes beyond the scope of philosophy, so I will leave this matter to the experts in that field.

Supporters of prohibition argued that it would solve the ills caused by alcohol. Ironically, prohibition ushered in more evils, such as creating a financial foundation for organized crime. While they were right about the ills of alcohol, their solution was mistaken.
Some years ago, researchers created “minibrains” which are more formally known as cerebral organoids. As the name implies, a minibrain is a pea-sized collection of a few million human neural cells. A human brain consists of about 85 billion cells. These minibrains are usually created by transforming human skin cells.
While exoskeletons are being developed primarily for military, medical and commercial applications, they have obvious potential for use in play. For example, new sports might be created in which athletes wear exoskeletons to enable greater performance.
Most players agree that playing tabletop role playing games (TTRPGs) should be fun. But at the table, and away from the table, people are subject to the
An exoskeleton is a powered frame that attaches to the body to provide support and strength. The movie Live, Die Repeat: Edge of Tomorrow featured combat exoskeletons. These fictional devices allow soldiers to run faster and longer while carrying heavier loads, giving them an advantage in combat. There are also peaceful applications of technology, such as allowing people with injuries to walk and augmenting human abilities for the workplace. For those concerned with fine details of nerdiness, exoskeletons should not be confused with cybernetic parts (these fully replace body parts, such as limbs or eyes) or powered armor (like that used in the novel Starship Troopers and by Iron Man).

While I sometimes get incredulous stares when I say this,
In the last essay I suggested that although a re-animation is not a person, it could be seen as a virtual person. This sort of virtual personhood can provide a foundation for a moral argument against re-animating celebrities. To make my case, I will use Kant’s arguments about the moral status of animals.
Supporters and critics of AI claim it will be taking our jobs. If true, this suggests that AI could eliminate the need for certain skills. While people do persist in learning obsolete skills for various reasons (such as for a hobby), it is likely that colleges would eventually stop teaching these “eliminated” skills. Colleges would, almost certainly, be able to adapt. For example, if AI replaced only a set of programming skills or a limited number of skills in the medical or legal professions, then degree programs would adjust their courses and curriculum. This sort of adaptation is nothing new in higher education and colleges have been adapting to changes since the beginning of higher education, whether these changes are caused by technology or politics. As examples, universities usually do not teach obsolete programming languages and state schools change their curriculum in response to changes imposed by state legislatures.
