This Start-Up Believes Seaweed Can Change the World
By Karen Scofield Seal
Demand for plant-based food and nutrition is growing. According to recent retail sales data, grocery sales of plant-based foods in place of animal products grew 29% in the U.S. to $5 billion between 2017 and 2019.
Sustainably farmed seaweed could help meet this need, while also providing compostable, marine-safe packaging. UK-based biotech start-up Oceanium has developed innovative, "green and clean" biorefinery technology to make both these things possible.
With grant funding from Innovate UK and seed investment from Sky Ocean Ventures and Katapult Ocean (the latter two being ocean impact VCs), is focusing on scaling up their high-tech, innovative biorefinery and product development to find out more about the start-up's history, development and plans for the future. We spoke to Oceanium's Karen Scofield to find out more about the start-up's history, development and plans for the future.
How Oceanium's technology works. Oceanium
How Did Oceanium Come About?
I met my Co-Founder and our CTO, Dr Charlie Bavington, PhD in May 2018. My background is in partnership and business development, brand-building and marketing. I've worked with (RED), Comic Relief and also run my own successful e-commerce business. After completing a postgraduate certificate at the University of Cambridge Institute for Sustainable Leadership, I conducted extensive research on what type of business I could start that would have the most impact and that's when I discovered seaweed. Ever since then, I have been passionate about sharing its environmental and societal benefits.
Charlie is a brilliant biochemist who has been developing and commercializing marine-based products for the past 20 years. He was the Founder of the successful biotech company, GlycoMar, and has extensive experience developing marine-based products for commercial use. He currently has five patents to his name and is about to file two more for Oceanium bio-packaging. I shared my vision of making packaging from seaweed with Charlie, who confirmed that this was possible but that there was also an opportunity to capitalize on all the food and nutritional ingredients in seaweed too. Charlie and I co-founded Oceanium in June 2018, and have been moving forward swiftly ever since.
How Is Oceanium Contributing to the Low-Carbon Economy?
Oceanium's impact mission is to enable the emerging sustainable seaweed farming industry by creating demand for farmed seaweed. Sustainable seaweed farming helps to mitigate climate change via carbon and nitrogen absorption. According to the World Bank, seaweed can absorb 47kg of carbon per wet tonne which equates to approximately one tonne of carbon per hectare annually.

Of course, some of that carbon will go back into the system. So we are conducting life-cycle analysis on our process and products so we may improve efficiencies but also to measure and report our impact as we grow and go to market. We are liaising with organizations like Seaweed for Europe and the UN Global Compact Seaweed Manifesto to help quantify this carbon absorption and to ensure this exciting new industry grows in a sustainable and managed fashion.
Seaweed farms protect the seabed from commercial fishing and other harmful practices and create a marine sanctuary for sea life. Seaweed farming also has other immensely positive environmental impacts, as it does not require cleared land, freshwater, insecticide or fertilizer. Our seaweed-based materials can replace resource-intensive food and feedstocks which often contribute to deforestation. In addition, seaweed farms encourage responsible coastal management and create marine protected areas for sealife.
What About the Economic and Societal Impact of Your Business?
Seaweed as a food source will help ensure food security. It's incredibly nutritious and full of vitamins, minerals and protein-essential micronutrients, particularly antioxidants.
The world will require 50–70% more food by 2050 and with increasing drought conditions and decreasing soil quality, seaweed provides a sustainable solution to this challenge.
Seaweed can help close the "protein gap" in the more immediate term: Europe currently imports 70% of its protein but Oceanium plans to process and sell its outputs on a regional basis to reduce transport miles of our products. We aim to contribute towards economic development and job creation in coastal communities by supporting small-scale farmers when purchasing seaweed, promoting best practice farming techniques and helping enable the nascent sustainable seaweed farming industry in the UK, EU and in the developing world.

What Has Been the Impact of COVID-19 on Oceanium?
Oceanium has continued to move forward despite the pandemic. At a start-up there is always plenty to do and we've been working on developing relationships across the value chain, researching and analyzing new opportunities, and conducting research. Interestingly, our nutraceutical product, Fucoidan, has proven to be an effective COVID-19 antiviral in vitro and we are watching this research closely.
What's Next on the Horizon?
Oceanium continues to progress with research and development for our food ingredients (protein and fiber), nutraceuticals (Fucoidan, Beta glucan) and circular life-cycle bio packaging materials (film and board).
We have also begun work on two new Innovate UK grants. The first is focused on further development of the bio-packaging materials; the second looks at maximizing efficiencies across all aspects of the production process, from the seaweed farm to final product development.

We are scaling our innovative biorefinery process – we processed approximately 8 tonnes of wet seaweed in December and have plans for 45 tonnes in 2021.
Meanwhile, we are continuing to build relationships with seaweed farmers in the UK, EU and North America. We are also fundraising for further R&D, patent applications and undergoing regulatory processes as we prepare to launch products in 2021. We are well on our way to "Kelp the World"!
What Resources or Assistance Do You Need to Achieve Your Ambitions That You Currently Don't Have? Is There Any Assistance That the Uplink Community Could Offer?
Definitely. Our nutraceutical products will go to market next year and we are looking for commercial or business development experts in the nutrition and cosmetics space. Importantly, we are also fundraising so always keen to connect with funders and investors!

The Earth's climate has always been a work in progress. In the 4.5 billion years the planet has been spinning around the sun, ice ages have come and gone, interrupted by epochs of intense heat. The highest mountain range in Texas was once an underwater reef. Camels wandered in evergreen forests in the Arctic. Then a few million years later, 400 feet of ice formed over what is now New York City. But amid this geologic mayhem, humans have gotten lucky. For the past 10,000 years, virtually the entire stretch of human civilization, people have lived in what scientists call "a Goldilocks climate" — not too hot, not too cold, just right.
Now, our luck is running out. The industrialized nations of the world are dumping 34 billion tons or so of carbon into the atmosphere every year, which is roughly 10 times faster than Mother Nature ever did on her own, even during past mass extinction events. As a result, global temperatures have risen 1.2 C since we began burning coal, and the past seven years have been the warmest seven years on record. The Earth's temperature is rising faster today than at any time since the end of the last ice age, 11,300 years ago. We are pushing ourselves out of a Goldilocks climate and into something entirely different — quite literally, a different world than humans have ever lived in before.
How hot will the summers get in India and Pakistan, and how will tens of thousands of deaths from extreme heat impact the stability of the region (both nations have nuclear weapons)? How close is the West Antarctic ice sheet to collapse, and what does the risk of five or six feet of sea-level rise mean for people living in mobile homes on the Gulf Coast? The truth is, no one knows for sure. We are in uncharted terrain. "We're now in a world where the past is no longer a good guide to the future," said Jesse Jenkins, an assistant professor of engineering at Princeton University. "We have to get much better at preparing for the unexpected."
By all indications, President Biden and his team understand all this. And it's hard not to feel that after 30 years of dithering and denial and hypocrisy, the fight to save the climate has finally begun in earnest. In the 2020 election, nearly 70 percent of Biden's voters said climate change was a top issue for them. Biden has staffed his administration with the climate A-team, from Gina McCarthy as domestic climate czar to John Kerry as international climate envoy. He has made racial and environmental justice a top priority. And perhaps most important of all, he sees the climate crisis as an opportunity to reinvent the U.S. economy and create millions of new jobs.
"I think in Obama's mind, it was always about tackling the climate challenge, not making the climate challenge the central element of your economic policy," says John Podesta, a Democratic power broker and special adviser to President Obama who played a key role in negotiating the Paris Agreement. "Biden's team is different. It is really the core of their economic strategy to make transformation of the energy systems the driver of innovation, growth, and job creation, justice and equity."
Of course, there have been hopeful moments before: the signing of the Kyoto Protocol in 1997, when the nations of the world first came together to limit CO2 emissions; the success of Al Gore's documentary An Inconvenient Truth in 2006; the election of Obama in 2008 ("This was the moment when the rise of the oceans began to slow and our planet began to heal," Obama said in his speech accepting the Democratic presidential nomination that year); the Paris Agreement in 2015, when China finally engaged in climate talks. But all of these moments, in the end, led to nothing. If you look at the only metric that really matters — a graph of the percentage of CO2 molecules in the atmosphere — it has been on a long, steady upward climb. More CO2 equals more heat. To put it bluntly, all our scientific knowledge, all the political speeches, all the activism and protest marches have done zero to stop the accumulation of CO2 in the atmosphere from the burning of fossil fuels.
But hope rises again. The economic winds are lifting Biden's sails: The cost of wind and solar power has plummeted by 90 percent or so over the past decade, and in many parts of the world it's the cheapest way to generate electricity. Meanwhile, fossil-fuel dinosaurs are tottering: Big Coal is collapsing in real time and may disappear from American life in the next decade or so. ExxonMobil lost $22 billion last year and in August was delisted from the S&P 500. GM, long the staunch fossil-fuel loyalist of the U.S. auto industry, has pledged to go all-electric by 2035.
Globally, the signs of change are equally inspiring. Eight of the 10 largest economies have pledged to reach net-zero emissions by 2050. China, by far the world's largest carbon polluter in terms of raw tonnage (on a per capita basis, the U.S. and several other countries pollute far more), has promised to become carbon neutral by 2060. Some 400 companies, including Microsoft, Unilever, Facebook, Ford, Nestlé, and Pepsi, have committed to reduce carbon pollution consistent with the United Nations' 1.5 C target, which scientists have determined is the threshold of dangerous climate change. Many of these same companies are now calling on the Biden administration to cut overall U.S. carbon pollution by at least 50 percent below 2005 levels by 2030, a goal consistent with the 1.5 C target.
Big Money is also waking up to the risks and benefits of climate action. In his annual letter to investors, Larry Fink, the CEO of BlackRock, which manages $7.8 trillion in assets, challenged companies "to disclose a plan for how their business model will be compatible with a net-zero economy." In her confirmation hearing, Treasury Secretary Janet Yellen called climate change "an existential threat" and promised to create a team to examine the risks and integrate them into financial policy-making.
Still, these are only baby steps in a very long journey. And the clock is ticking. "When it comes to the climate crisis," says futurist Alex Steffen, "speed is everything." Every molecule of carbon we dump into the atmosphere is another molecule of carbon that will warm the climate for centuries to come, and in subtle and not-so-subtle ways, reshape the world we live in. The changes we are making are not reversible. If we magically stopped all carbon pollution tomorrow, the Earth's temperature would level off, but warm seas would continue melting the ice sheets and seas would keep rising for decades, if not centuries (last time carbon levels were as high as they are today, sea levels were 70 feet higher). Ocean acidification, caused by high CO2 levels, is already dissolving coral reefs and is having a major impact on the ocean food chain. Even after emissions stop, it will take the ocean thousands of years to recover.
Cutting carbon fast would slow these changes and reduce the risk of other climate catastrophes. But despite the world's newfound ambition, political leaders are not moving anywhere near fast enough. Even the goal of holding future warming to 2 C, which is a centerpiece of the Paris Agreement and considered the outer limits of a Goldilocks climate for much of the planet, is nearly out of reach. As a recent paper in Nature pointed out: "On current trends, the probability of staying below 2 C of warming is only five percent." If all countries meet the commitment they made in the 2015 Paris Agreement and continue to reduce emissions at the same rate after 2030, the paper argued, the probability of remaining below 2 C of warming rises to 26 percent ("As if a 26 percent chance was good," Swedish climate wunderkind Greta Thunberg pointed out in a tweet).
The great danger is not climate denial. The great danger is climate delay. Instead of pushing for changes tomorrow, world leaders and CEOs like to make virtuous-sounding statements about what they will do in 2050. And then in 2050, they will make virtuous-sounding statements about what they will do in 2070. Climate scientist Zeke Hausfather calls this the "empty radicalism" of long-term goals.
What's needed is action now. As climate envoy John Kerry put it at the World Sustainable Development Summit in February: "We have to now phase out coal five times faster than we have been. We have to increase tree cover five times faster than we have been. We have to ramp up renewable energy six times faster than we are. We have to transition to [electric vehicles] 22 times faster."
As an example of the seriousness of Biden's near-term ambition, he has proposed transitioning to 100 percent clean electricity by 2035, which means goodbye natural-gas plants, goodbye coal plants, and hello electric cars and battery storage. It's an astonishingly ambitious proposal, one that would require a remaking of the digital backbone of America at a breakneck speed. It will create hundreds of thousands of jobs, but if Biden is serious about getting it done, it will require retooling permitting laws and the environmental-review process that often stalls big infrastructure projects.
Demanding action now will also require shutting down the international financing schemes that support fossil fuels. China, Japan, and South Korea all claim to be doing their part in making carbon reductions at home, while at the same time they are financing 70,000 megawatts of coal power in places like Bangladesh, Vietnam, and Indonesia. In addition, state-run oil companies in places like China, Indonesia, and Saudi Arabia are on course to spend more than $400 billion over the next decade to expand oil infrastructure and exploration.
The goal of net-zero emissions is also problematic. "Net zero" is not the same thing as zero. It means that carbon pollution is either eliminated or offset by other processes that remove carbon from the atmosphere, such as forests or machines that capture CO2. Some of these offsets and technologies are more legit than others, opening the door to scams that claim to eliminate more carbon than they do.
In a way, the economic chaos caused by the pandemic has created a historic opportunity for the Biden administration. As one White House adviser tells me, "If you are going to pump billions of dollars into the economy, why not use those dollars to help us transition away from fossil fuels?" This is one of the central ideas behind Biden's $2 trillion infrastructure bill, which is now being negotiated in Congress. The bill includes a wide variety of climate-related initiatives, shaped around the twin pillars of Biden-era policy: clean-energy jobs and climate justice.
Already the pushback is fierce, especially in states that have benefited from the fracking boom. "The climate fight going forward is really about natural gas," says Leah Stokes, author of Short Circuiting Policy, an analysis of how special interests have derailed clean-energy policy for 30 years. Shortly after Biden issued his first round of executive orders aimed at the climate crisis, Texas Gov. Greg Abbott held a press conference in the middle of the gas fields "to make clear that Texas is going to protect the oil-and-gas industry from any type of hostile attack launched from Washington, D.C." In Florida, two bills were introduced that would preempt local governments from implementing plans to lower carbon pollution. In California and New York, residents are fighting transmission lines for offshore wind farms. Republicans, along with stalwart fossil-fuel allies like the Heritage Foundation, recently convened a private retreat in Utah to plot ways to "reclaim the narrative" on climate, while Republican Senators like Tennessee's Marsha Blackburn continue to recycle tired old rants about how the Paris Agreement is destroying American jobs.
None of this is surprising. And the fight will only get bigger and more ruthless as the clean-energy transition accelerates. Fossil fuels are emblematic of a culture, a way of life, a political hierarchy, and an empire of wealth that will not go quietly into the night.
Even among climate activists and progressives, there is wide disagreement about the best path forward. In Pennsylvania, Rep. Conor Lamb, a Democrat who supports Biden's climate goals, sees natural gas as indispensable. "You can't turn off natural gas in our society, at least in the Northeast of the United States at this time," Lamb tells me. "You just can't do it." Lamb advocates investments in expensive and unproven technology like carbon capture that could extend the life of fossil fuels. Then there are the eternal battles over nuclear power as a source of clean energy, which Lamb also supports. Others, like UC Berkeley energy professor Daniel Kammen, remain skeptical: "If low-cost, reliable, entirely safe nuclear can prove itself out, this is wonderful. . . . But there's a lot of big ifs."
More important, the fight for a stable climate is increasingly inseparable from a fight for justice and equity. Catherine Coleman Flowers, who was on a task force that helped shape Biden's climate policy during his campaign, grew up and works in Lowndes County, Alabama. "I see a lot of poverty here," Flowers says. "And I see a lot of people who suffer from the impacts of climate change — whether it is heat, or disease, or poor sanitation and polluted drinking water. You can't separate one from the other. They put sewage lagoons next to the houses of poor people, not rich people. They put oil pipelines through poor neighborhoods, not rich ones."
Internationally, rich nations of the world pledged to "mobilize" $100 billion by 2020 through the U.N.'s Green Climate Fund to help developing nations adapt to climate change. But only about $10 billion materialized. The U.S. was among the worst actors: Of the $3 billion President Obama promised, he funded only $1 billion before Trump canceled further payments (Biden has promised to make good on the commitment, and then some).
Whatever happens with Biden's climate and energy initiatives, we're living in a new world now. The faster we cut carbon, the more manageable the changes will be. But change is coming. The biggest fights of the future are less likely to be about natural gas and nuclear power than about sea walls and migration policies. "Adaptation is not sexy," says Alice Hill, who was an adviser to the Obama administration. "But it is inevitable." As climate impacts escalate, dangerous techno-fixes, such as solar geoengineering, which involves spraying particles into the stratosphere to reflect away sunlight and cool the planet, will likely become more tempting and more divisive, perhaps further diluting the will to quickly cut carbon pollution.
For more than 30 years now, scientists and politicians have been aware that our hellbent consumption of fossil fuels could push us out of the Goldilocks zone and force humans to live in a world we have never inhabited before. As Biden's push for climate action gets real, we will learn a lot about how serious human beings are about living on this planet, and how far the powerful and privileged are willing to go to reduce the suffering of the poor and vulnerable. If political leaders don't take the climate crisis seriously now, with all they know, with all they have been through already, will they ever? "Climate advocates keep saying, 'This is it, this is it, this is it,'" warns Podesta. "But this really is it. If we don't amp up and accelerate the energy transformation in this decade, we're goners — really goners."

Ecologists and environmental advocates on Thursday called for swift action to reintroduce species into the wild as scientists at the University of Cambridge in England found that 97% of the planet's land area no longer qualifies as ecologically intact.
"Conservation is simply not enough anymore," said financier and activist Ben Goldsmith. "We need restoration."
Just 3% of world’s ecosystems now remain intact. Conservation is simply not enough anymore. We need restoration. https://t.co/iWcLxAoLWn— Ben Goldsmith (@Ben Goldsmith)1618487636.0
The authors of the study, published in the journal Frontiers in Forests and Global Change, expressed alarm at their findings, which showed that of the 3% of fully intact land, much lies in northern areas which weren't rich in biodiversity to begin with, such as boreal forests in Canada or tundra in Greenland.
The amount of ecologically intact land "was much lower than we were expecting," Dr. Andrew Plumptre, head of the Key Biodiversity Areas Secretariat at Cambridge and lead author of the study, told Science News.
"Going in, I'd guessed that it would be 8 to 10%," he added. "It just shows how huge an impact we've had."
The researchers examined whether natural habitats had retained the number of species which were present in the year 1500—the standard used by the International Union for the Conservation of Nature to assess species' extinction.
Earlier research using satellite imagery led to estimates that 20 to 40% of the planet had retained its natural biodiversity. But areas including dense forests, which can appear intact from above, were found to be missing numerous species.
The researchers linked the loss of unscathed land to hunting and other destructive human activities, disease, and the impact of invasive species. According to The Guardian, the study may underestimate the intact regions because it does not "take account of the impacts of the climate crisis, which is changing the ranges of species."
Only 11% of the land still considered intact was found to be in officially protected areas, but much of the intact regions "coincide with territories managed by indigenous communities, who have played a vital role in maintaining the ecological integrity of these areas," the researchers wrote.
In light of the study, advocates including author George Monbiot and ecologist Alan Watson Featherstone called for "rewilding," or species reintroduction in affected areas.

The reintroduction of up to five species could help restore 20% of the planet to previous levels of biodiversity, the study found.
"Examples would include reintroducing forest elephants in areas of the Congo Basin where they have been extirpated, or reintroducing some of the large ungulates that have been lost from much of Africa's woodlands and savannas because of overhunting (e.g., buffalo, giraffe, zebras etc.), as long as overhunting has ceased," the researchers wrote.
Previously, the rewilding of gray wolves in Yellowstone National Park in the U.S. led to a resurgence in the park's ecosystem.

Google's New Timelapse Shows 37 Years of Climate Change Anywhere on Earth, Including Your Neighborhood
Google Earth's latest feature allows you to watch the climate change in four dimensions.
The new feature, called Timelapse, is the biggest update to Google Earth since 2017. It is also, as far as its developers know, the largest video taken of Earth on Earth. The feature compiles 24 million satellite photos taken between 1984 and 2020 to show how human activity has transformed the planet over the past 37 years.
"Visual evidence can cut to the core of the debate in a way that words cannot and communicate complex issues to everyone," Google Earth Director Rebecca Moore wrote in a blog post Thursday.
Moore herself has been directly impacted by the climate crisis. She was one of many Californians evacuated because of wildfires last year. However, the new feature allows people to witness more remote changes, such as the melting of ice caps.
"With Timelapse in Google Earth, we have a clearer picture of our changing planet right at our fingertips — one that shows not just problems but also solutions, as well as mesmerizingly beautiful natural phenomena that unfold over decades," she wrote.
Some climate impacts that viewers can witness include the melting of 12 miles of Alaska's Columbia Glacier between 1984 and 2020, Fortune reported. They can also watch the disintegration of the Pine Island Glacier in Antarctica. The changes are not limited to the impacts of global warming, however.
Moore said the developers had identified five themes, and Google Earth offers a guided tour for each of them. They are:
- Forest change, such as deforestation in Bolivia for soybean farming
- Urban growth, such as the quintupling of Las Vegas sprawl
- Warming temperatures, such as melting glaciers and ice sheets
- Sources of energy, such as the impacts of coal mining on Wyoming's landscape
- Fragile beauty, such as the flow of Bolivia's Mamoré River
However, the feature also allows you to see smaller-scale change. You can enter any location into the search bar, including your local neighborhood, CNN explained. The feature does not offer the detail of Street View, Gizmodo noted. It is intended to show large changes over time, rather than smaller details like the construction of a road or home.
The images for Timelapse were made possible through collaboration with NASA, the U.S. Geological Survey's Landsat satellites and the European Union's Copernicus program and Sentinel satellites. Carnegie Mellon University's CREATE Lab helped develop the technology.
To use Timelapse, you can either visit g.co/Timelapse directly or click on the Ship's Wheel icon in Google Earth, then select Timelapse. Moore said the feature would be updated annually with new images of Earth's alterations.
"We hope that this perspective of the planet will ground debates, encourage discovery and shift perspectives about some of our most pressing global issues," she wrote.

Imagine seeing a news report about lead contamination in drinking water in a community that looks like yours. It might make you think twice about whether to drink your tap water or serve it to your kids – especially if you also have experienced tap water problems in the past.
In a new study, my colleagues Anisha Patel, Francesca Weaks and I estimate that approximately 61.4 million people in the U.S. did not drink their tap water as of 2017-2018. Our research, which was released in preprint format on April 8, 2021, and has not yet been peer reviewed, found that this number has grown sharply in the past several years.
Other research has shown that about 2 million Americans don't have access to clean water. Taking that into account, our findings suggest that about 59 million people have tap water access from either their municipality or private wells or cisterns, but don't drink it. While some may have contaminated water, others may be avoiding water that's actually safe.
Water insecurity is an underrecognized but growing problem in the U.S. Tap water distrust is part of the problem. And it's critical to understand what drives it, because people who don't trust their tap water shift to more expensive and often less healthy options, like bottled water or sugary drinks.
I'm a human biologist and have studied water and health for the past decade in places as diverse as Lowland Bolivia and northern Kenya. Now I run the Water, Health, and Nutrition Laboratory at Pennsylvania State University. To understand water issues, I talk to people and use large datasets to see whether a problem is unique or widespread, and stable or growing.
An Epidemic of Distrust
According to our research, there's a growing epidemic of tap water distrust and disuse in the U.S. In a 2020 study, anthropologist Sera Young and I found that tap water avoidance was declining before the Flint water crisis that began in 2014. In 2015-2016, however, it started to increase again for children.
Our new study found that in 2017-2018, the number of Americans who didn't drink tap water increased at an alarmingly high rate, particularly for Black and Hispanic adults and children. Since 2013-2014 – just before the Flint water crisis began – the prevalence of adults who do not drink their tap water has increased by 40%. Among children, not consuming tap has risen by 63%.
To calculate this change, we used data from the National Health and Nutrition Examination Survey, a nationally representative survey that releases data in two-year cycles. Sampling weights that use demographic characteristics ensure that the people being sampled are representative of the broader U.S. population.
Racial Disparities in Tap Water Consumption
Communities of color have long experienced environmental injustice across the U.S. Black, Hispanic and Native American residents are more likely to live in environmentally disadvantaged neighborhoods, with exposure to water that violates quality standards.
Our findings reflect these experiences. We calculated that Black and Hispanic children and adults are two to three times more likely to report not drinking their tap water than members of white households. In 2017-2018, roughly 3 out of 10 Black adults and children and nearly 4 of 10 Hispanic adults and children didn't drink their tap water. Approximately 2 of 10 Asian Americans didn't drink from their tap, while only 1 of 10 white Americans didn't drink their tap water.
When children don't drink any water on a given day, research shows that they consume twice as many calories from sugary drinks as children who drink water. Higher sugary drink consumption increases risk of cavities, obesity and cardiometabolic diseases. Drinking tap water provides fluoride, which lowers the risk of cavities. Relying on water alternatives is also much more expensive than drinking tap water.

What Erodes Trust
News reports – particularly high-visibility events like advisories to boil water – lead people to distrust their tap water even after the problem is fixed. For example, a 2019 study showed that water quality violations across the U.S. between 2006 and 2015 led to increases in bottled water purchases in affected counties as a way to avoid tap water, and purchase rates remained elevated after the violation.
The Flint water crisis drew national attention to water insecurity, even though state and federal regulators were slow to respond to residents' complaints there. Soon afterward, lead contamination was found in the water supply of Newark, New Jersey; the city is currently replacing all lead service lines under a legal settlement. Elsewhere, media outlets and advocacy groups have reported finding tap water samples contaminated with industrial chemicals, lead, arsenic and other contaminants.
Many other factors can cause people to distrust their water supply, including smell, taste and appearance, as well as lower income levels. Location is also an issue: Older U.S. cities with aging infrastructure are more prone to water shutoffs and water quality problems.
It's important not to blame people for distrusting what comes out of their tap, because those fears are rooted in history. In my view, addressing water insecurity requires a two-part strategy: ensuring that everyone has access to clean water, and increasing trust so people who have safe water will use it.
As part of his proposed infrastructure plan, President Joe Biden is asking Congress for $111 billion to improve water delivery systems, replace lead pipelines and tackle other contaminants. The plan also proposes improvements for small water systems and underserved communities.
These are critical steps to rebuild trust. Yet, in my view, the U.S. Environmental Protection Agency should also provide better public education about water quality testing and targeted interventions for vulnerable populations, such as children and underserved communities. Initiatives to simplify and improve water quality reports can help people understand what's in their water and what they can do if they think something is wrong with it.
Who delivers those messages is important. In areas like Flint, where former government officials have been indicted on charges including negligence and perjury in connection with the water crisis, the government's word alone won't rebuild trust. Instead, community members can fill this critical role.
Another priority is the 13%-15% of Americans who rely on private well water, which is not regulated under the Safe Drinking Water Act. These households are responsible for their own water quality testing. Public funding would help them test it regularly and address any problems.
Public distrust of tap water in the U.S. reflects decades of policies that have reduced access to reliable, safe drinking water in communities of color. Fixing water lines is important, but so is giving people confidence to turn on the tap.

A new report promoting urgent climate action in Australia has stirred debate for claiming that global temperatures will rise past 1.5 degrees Celsius in the next decade.
Australia's Climate Council released the report on Thursday. The council is an independent organization of climate scientists and experts on health, renewable energy and policy who work to inform the Australian public on the climate crisis. But their latest claim is causing controversy.
"Multiple lines of evidence show that limiting global warming to 1.5°C above the preindustrial level, without significant overshoot and subsequent drawdown, is now out of reach due to past inaction," Dr. Kevin Trenberth of the National Center for Atmospheric Research and Prof. Christopher Field of the Stanford Woods Institute for the Environment wrote in the foreword. "The science is telling us that global average temperature rise will likely exceed 1.5°C during the 2030s, and that long-term stabilization at warming at or below 1.5°C will be extremely challenging."
The report is titled "Aim high, go fast: Why emissions need to plummet this decade," and as the name suggests, it is ultimately concerned with urging more robust climate action on the part of the Australian government. The report calls for the country to reduce emissions by 75 percent by 2030 and reach net zero by 2035 in order to achieve the long-term goals of the Paris agreement, which means limiting warming to well below two degrees Celsius.
"The world achieving net zero by 2050 is at least a decade too late and carries a strong risk of irreversible global climate disruption at levels inconsistent with maintaining well-functioning human societies," the authors wrote.
The report further argues that global temperatures are likely to exceed 1.5 degrees Celsius in the 2030s based on existing temperature increases; locked-in warming from emissions that have already occurred; evidence from past climate changes and the percentage of the carbon budget that has already been used.
The report isn't a call to give up on the Paris agreement. It is possible that global temperatures could swell past 1.5 degrees Celsius but still be reduced by removing carbon dioxide from the atmosphere. Even if temperatures do exceed 1.5 degrees, every degree of warming that can be prevented makes a difference.
"Basically we can still hold temperature rise to well below 2C and do that without overshoot and drawdown," Will Steffen, lead report author from the Australian National University's Climate Change Institute, told Australia's ABC News. "Every tenth of a degree actually does matter — 1.8C is better than 1.9C, and is much better than 2C."
However, some outside scientists question both the accuracy and effectiveness of the report's claim. Both Adjunct Professor Bill Hare from Murdoch University and Dr. Carl-Freidrich Schleussner from Humboldt University told ABC News they have been trying to contact the Climate Council about its 1.5 overshoot claim for months. They said that it went against other major reports, including the UN Environment Program Gap Report and the recent Intergovernmental Panel on Climate Change Special Report on 1.5˚C.
"The big challenge their report reinforces is the need for urgent action to get on that 1.5C pathway, [so] it's very paradoxical to me that they've chosen to attack that target," Dr. Hare told ABC News.
However, Scientist Andy Pitman from the Center of Excellence for Climate Extremes at the University of New South Wales told The Guardian that the report's assessment was correct.
"It's simply not possible to limit warming to 1.5C now," he said. "There's too much inertia in the system and even if you stopped greenhouse gas emissions today, you would still reach 1.5C [of heating]."
However, one aspect everyone agreed on involved the importance of lowering emissions as soon as possible.
"[There is] absolute fundamental agreement on the task at hand, which is to get emissions to plummet," Simon Bradshaw, report author and Climate Council head of research, told The Guardian.
