In my research on daylight saving time, I have found that Americans don't like it when Congress messes with their clocks.

In an effort to avoid the biannual clock switch in spring and fall, some well-intended critics of DST have made the mistake of suggesting that the abolition of DST – and a return to permanent standard time – would benefit society. In other words, the U.S. would never "spring forward" or "fall back."


They are wrong. DST saves lives and energy and prevents crime. Not surprisingly, then, politicians in Washington, California and Florida are now proposing to move to DST year-round.

Congress should seize on this momentum to move the entire country to year-round DST. In other words, turn all clocks forward permanently. If it did so, I see five ways that Americans' lives would immediately improve.

Daylight Saving Time - How Is This Still A Thing?: Last Week Tonight with John Oliver (HBO) youtu.be

1. Lives would be saved.

Simply put, darkness kills – and darkness in the evening is far deadlier than darkness in the morning.

The evening rush hour is twice as fatal as the morning for various reasons: Far more people are on the road, more alcohol is in drivers' bloodstreams, people are hurrying to get home and more children are enjoying outdoor, unsupervised play. Fatal vehicle-on-pedestrian crashes increase threefold when the sun goes down.

DST brings an extra hour of sunlight into the evening to mitigate those risks. Standard time has precisely the opposite impact, by moving sunlight into the morning.

A meta-study by Rutgers researchers demonstrated that 343 lives per year could be saved by moving to year-round DST. The opposite effect would occur if the U.S. imposed year-round standard time.

2. Crime would decrease.

Darkness is also a friend of crime. Moving sunlight into the evening hours has a far greater impact on the prevention of crime than it does in the morning. This is especially true for crimes by juveniles, which peak in the after-school and early evening hours.

Criminals strongly prefer to do their work in the darkness of evening and night. Crime rates are lower by 30 percent in the morning to afternoon hours, even when those morning hours occur before sunrise, when it's still dark.

A 2013 British study found that improved lighting in the evening hours could reduce the crime rate by up to 20 percent.

3. Energy would be saved.

Many people don't know that the original justification for the creation of DST was to save energy, initially during World War I and II and then later during the 1973 OPEC oil crisis. When the sun is out later in the evening, peak energy loads are reduced.

Virtually everyone in our society is awake and using energy in the early evening hours when the sun sets. But a considerable portion of the population is still asleep at sunrise, resulting in significantly less demand for energy then.

Having more sun in the evening requires not just less electricity to provide lighting, but reduces the amount of oil and gas required to heat homes and businesses when people need that energy most. Under standard time, the sun rises earlier, reducing morning energy consumption, but only half of Americans are awake to be able to use the sun.

This rationale motivated some in California to recommend permanent DST a decade ago, when the state experienced recurrent electricity shortages and rolling brown-outs. Officials at the California Energy Commission estimated that 3.4 percent of California's winter energy usage could be saved by moving to year-round DST.

Similarly, DST resulted in 150,000 barrels of oil saved by the U.S. in 1973, which helped combat the effect of OPEC's oil embargo.

4. Avoiding clock switches improves sleep.

Critics of DST are correct about one thing: The biannual clock switch is bad for health and welfare.

It wreaks havoc with people's sleep cycles. Heart attacks increase 24 percent in the week after the U.S. "springs forward" in March. There's even an uptick during the week in November when the clocks "fall back."

If that's not bad enough, a study from 2000 shows that the major financial market indexes NYSE, AMEX and NASDAQ average negative returns on the Monday trading day following both clock switches, presumably because of disrupted sleep cycles.

5. Recreation and commerce flourish in the sun.

Finally, recreation and commerce flourish in daylight and are hampered by evening darkness.

Americans are less willing to go out and shop in the dark, and it's not very easy to catch a baseball in darkness either. These activities are far more prevalent in the early evening than they are in the early morning hours, so sunlight is not nearly as helpful then.

Not surprisingly, the U.S. Chamber of Commerce as well as most outdoor recreational interests favors extended DST.

Research shows that sunlight is far more important to Americans' health, efficiency and safety in the early evening than it is in the early morning. That's not to say there aren't downsides to DST – notably, an extra hour of morning darkness. But I believe the advantages of extended DST far outweigh those of standard time. It is past time that the U.S. sets the clocks forward forever, and never has to switch them again.

It is far too easy to view scarcity and poor quality of water as issues solely affecting emerging economies. While the images of women and children fetching water in Africa and a lack of access to water in India are deeply disturbing, this is not the complete picture.

The city of Flint, Michigan, where dangerous levels of pollutants contaminated the municipal water supply, is a case in point — as is, more recently, the city of Newark, New Jersey.

The Past is No Longer a Guide to the Future

We get ever closer to "day zeros" — the point at when municipal water supplies are switched off — and tragedies such as Flint. These are not isolated stories. Instead they are becoming routine, and the public sector and civil society are scrambling to address them. We are seeing "day zeros" in South Africa, India, Australia and elsewhere, and we are now detecting lead contamination in drinking water in cities across the U.S.

"Day zero" is the result of water planning by looking in the rear-view mirror. The past is no longer a guide to the future; water demand has outstripped supplies because we are tied to business-as-usual planning practices and water prices, and this goes hand-in-hand with the inability of the public sector to factor the impacts of climate change into long-term water planning. Lead in drinking water is the result of lead pipe service lines that have not been replaced and in many cases only recently identified by utilities, governments and customers. An estimated 22 million people in the US are potentially using lead water service lines. This aging infrastructure won't repair or replace itself.

One of the most troubling aspects of the global water crisis is that those least able to afford access to water are also the ones who pay a disproportionately high percentage of their income for it. A report by WaterAid revealed that a standard water bill in developed countries is as little as 0.1 percent of the income of someone earning the minimum wage, while in a country like Madagascar a person reliant on a tanker truck for their water supply would spend as much as 45 percent of their daily income on water to get just the recommended daily minimum supply. In Mozambique, families relying on black-market vendors will spend up to 100 times as much on water as those reached by government-subsidized water supplies.

Finally, we need to understand that the discussion of a projected gap between supply and demand is misleading. There is no gap, only poor choices around allocation. The wealthy will have access to water, and the poor will pay more for water of questionable quality. From Flint residents using bottled water and paying high water utility rates, to the poor in South Africa waiting in line for their allocation of water — inequity is everywhere.

Water Inequity Requires Global Action — Now.

These troubling scenarios beg the obvious question: What to do? We do know that ongoing reports on the 'water crisis' are not going to catalyze action to address water scarcity, poor quality, access and affordability. Ensuring the human right to water feels distant at times.

We need to mobilize an ecosystem of stakeholders to be fully engaged in developing and scaling solutions. The public sector, private sector, NGOs, entrepreneurs, investors, academics and civil society must all be engaged in solving water scarcity and quality problems. Each stakeholder brings unique skills, scale and speed of impact (for example, entrepreneurs are fast but lack scale, while conversely the public sector is slow but has scale).

We also urgently need to change how we talk about water. We consistently talk about droughts happening across the globe — but what we are really dealing with is an overallocation of water due to business-as-usual practices and the impacts of climate change.

We need to democratize access to water data and actionable information. Imagine providing anyone with a smartphone the ability to know, on a real-time basis, the quality of their drinking water and actions to secure safe water. Putting this information in the hands of civil society instead or solely relying on centralized regulatory agencies and utilities will change public policies.

It may seem innocuous to flush a Q-tip down the toilet, but those bits of plastic have been washing up on beaches and pose a threat to the birds, turtles and marine life that call those beaches home. The scourge of plastic "nurdles," as they are called, has pushed Scotland to implement a complete ban on the sale and manufacture of plastic-stemmed cotton swabs, as the BBC reported.
