Climate-induced sea level rise will lead to dangerous levels of arsenic being released into Bangladesh’s drinking water, putting tens of millions of people in the country at greater risk of cancer, new research by scientists from Norwich University has found.

Scientists say global heating due to human-caused climate change will lead to extreme weather, sea level rise and flooding, which will speed up the release of arsenic into the well water nearly half the country relies on.

“Over 165,000,000 people live in Bangladesh; approximately 97% of Bangladeshis drink well water. Approximately 49% of Bangladesh’s area has drinking well water with arsenic (As) concentrations that exceed the 10 micrograms per liter (μg/L) World Health Organization (WHO) guideline,” the authors of the study wrote.

The researchers said this will escalate the country’s current public health crisis, reported The Guardian.

“Chronic arsenic poisoning from drinking water… is a real problem, not a theoretical exercise,” said Dr. Seth Frisbie, research lead and a Norwich University emeritus professor of chemistry, as The Guardian reported. “I once walked into a village where no one was over 30 years old.”

The study, “Sea level rise from climate change is expected to increase the release of arsenic into Bangladesh’s drinking well water by reduction and by the salt effect,” was published in the journal PLOS One.

The problem of arsenic water contamination in Bangladesh started in the 1970s, when the country had one of the highest infant mortality rates caused by surface water pollution. A program of boring into sedimentary rocks to access clean water had been sponsored by aid agencies from the United Nations and NGOs. The wells lowered the rates of infant mortality, but in the following two decades it was obvious that the water had naturally high arsenic levels.

Jamie Williams, senior policy advisor with NGO Islamic Relief, said the country has been experiencing water shortages because of pesticide pollution, especially in fishing regions, reported The Independent.

“Bangladesh is one of the most vulnerable countries to climate change due to its population density, and limited low-lying land area dominated by major rivers that drain the Himalayan mountains and foothills,” Williams told The Independent. “Many people are landless and forced to live on and cultivate flood-prone land; waterborne diseases are prevalent.”

Bangladesh had its first chronic arsenic poisoning case from drinking well water in 1993, which WHO described as the “largest mass poisoning of a population in history,” The Guardian said.

According to Frisbie, sediments washed down from the uplift of the Himalayas contain arsenic.

“So all the sediments from the Ganges, Brahmaputra, Meghna, Irrawaddy [and] Mekong river basins are rich in naturally occurring arsenic,” Frisbie said. “It wasn’t a problem when people drank surface water, because the surface water is in communication with the oxygen in the atmosphere and that makes the arsenic insoluble and removes it from the water. But the deep well water does not communicate as well with the oxygen in the atmosphere. And that’s why all of a sudden giving people access to these deep water wells has been a tremendous public health crisis.”

Frisbie said approximately 45 percent of the country’s wells have water with five times or more the maximum WHO limit for arsenic.

Arsenic builds up in organs inside the body, causing cancers. Chronic arsenic poisoning can also manifest as keratinization on people’s palms and the soles of their feet.

“My current estimate is about 78 million Bangladeshis are exposed, and I believe a conservative estimate is that about 900,000 Bangladeshis are expected to die from lung and bladder cancer,” Frisbie said, according to The Guardian.

The climate crisis will make the situation worse, as sea level rise is predicted to cause more flooding in the country. This will trigger a process called “reduction,” which will alter aquifer chemistry and lead to greater arsenic leaching from sediment.

Sea level rise will also cause aquifers to be inundated with seawater, increasing their salinity. That will speed up the leaching of arsenic through a process called “the salt effect.”

The effects of climate change on the underlying chemistry of water drawn from aquifers is not only a problem in Bangladesh.

“These chemical processes are global,” said Frisbie in The Guardian. “There’s this reduction of arsenic in Manchester, there’s the salt effect in Louisiana [because of] floods like Hurricane Katrina. So because these are universal chemical processes, this is a global problem.”

Can You Recycle Computers?

Published

on

Last Updated on January 21, 2026

Picture this: Your laptop of three years decides it’s going to conk out. What’s the most sustainable solution? Seeing if you can get it repaired, of course.

Fighting planned obsolescence is a full time job, and it occurs with way more than just electronics. 

Can You Recycle Computers?

But lets say you can’t repair your laptop for some unforeseeable reason…what then? You recycle it of course.  

Computers don’t belong in landfills, nor do most conventional curbside recycling programs accept them. So how do you recycle computers? Here’s everything you need to know about computer recycling (and why we need to dispose of them properly).

why should you recycle computers?

First, lets tackle the reason we should bother to recycle computers. Computers are made up of several components – and when we dump them out, they become notorious for leaking toxins and carcinogens into the environment. This poses a risk for humans, wildlife, and soil quality alike. 

However, if we recycle computers, all those components get a second shot at life. There are several valuable materials in our old computers that can be used to make new electronics, thus reducing waste and pollution.

According to the EPA, recycling 1 million laptops saves enough energy to power ~3,500 U.S. homes for a year.

And if that’s not reason enough – improperly disposed computers can put your personal or business files at risk of being recovered. And that can escalate to data breaches or reputation damage (yikes).

Can You Recycle Computers?

how do I get rid of my old computer?

To get rid of your old computer, you must first back up your data, sign out of all accounts, wipe & destroy the hard drive, then recycle the computer through local e-waste centers or retailers with take-back programs (Best Buy, Staples, etc.).

To wipe a hard drive, be sure to back up any important data first. Use built-in tools like ‘reset this PC’ or check with your computer’s manufacturer to see specific instructions. For example, here’s how to wipe a Dell hard drive and erase a Mac hard drive.

For absolutely no chance of your data being recovered, it’s always best to remove and destroy the hard drive, if possible. Here’s a guide to destroying a hard drive safely.

Once the hard drive is no longer an issue, you can recycle computers through a number of drop-off or mail-in options.

drop off: 

  • Local e-waste recycling events (make sure to ask if your specific computer will be accepted in advance). Check your local .gov to see when your next one will be!
  • Best Buy accepts various desktops, laptops, and tablets, including some accessories. There’s a limit of 3 items per household per day. They charge a small fee for recycling monitors. 
  • Staples accepts computers & Macs. They charge a fee for monitors. When you recycle, you get rewards with their store! 
  • Use ERI’s recycle search and find recycling locations near you. Just type in “computer recycling” and your zip code to learn what your options are. 

mail-in:  

  • Several manufacturers will accept mail-in recycling for their computer models. Dell and HP have trade-in programs for computers that meet certain standards, as well as recycling options for lesser functioning computers of any brand. Apple also accepts trade-in and recycling for several devices, including computers.  
  • Green Citizen offers free mail-in recycling for laptops, desktops, and tablets, but there may be fees for data destruction.  

Most of these places will also accept computer accessories, like keyboards, mice, etc. But be sure to double check!

Can You Recycle Computers?

should you remove the hard drive from a computer before recycling?

Yes, always remove the hard drive before recycling. It’s best to wipe it, then remove it and destroy it. Because even a wiped hard drive can still be recovered, to an extent.

Even if you empty the recycling bin on your computer it doesn’t guarantee that the content is gone because the computer marks that data space to be overwritten with new data. So if the data hasn’t been overwritten, data recovery software can pick it up.

does best buy erase hard drives when recycling? 

Best Buy offers tips and advice on wiping hard drives and data for Windows computers prior to drop off, but won’t actually do it for you. It’s best to go prepared by wiping/destroying your hard drive first.

So, what did you think of this guide to recycling computers? Let me know in the comments!

The carbon removal industry stands at a crucial crossroads. While cutting emissions remains essential, avoiding catastrophic warming now requires pulling billions of tons of CO2 from the atmosphere permanently. But as this nascent field grapples with questions of legitimacy, scalability, and accountability, a critical challenge remains: How do we build the infrastructure needed to track, verify, and certify that carbon has actually been removed and stays removed? Meet Hannes Junginger-Gestrich, CEO of Carbonfuture, a company helping define the monitoring, reporting, and verification (MRV) infrastructure that could transform carbon removal from scattered efforts into a functioning ecosystem. Launched five years ago, Carbonfuture has emerged as what CDR.fyi describes as “the largest facilitator of durable carbon removal” by volume. The company’s digital platform integrates data across the carbon removal life cycle, connecting diverse approaches like biochar, enhanced rock weathering, and direct air capture with buyers seeking to meet climate commitments. “We are probably more the crowd, the ground keepers in a stadium that makes sure that everything is provided properly,” Hannes explains, using a sports analogy to describe their role: “We are the ground keepers in a stadium [who ensure] the players have a playing field that’s in shape and no one gets hurt, and the audience can come and they pay their tickets and have a good experience.”

Hannes Junginger-Gestrich, CEO of Carbonfuture, is our guest on Sustainability In Your Ear.

The MRV infrastructure becomes crucial as corporate demand for verified carbon removal grows and trust becomes currency. One of the most interesting aspects of the conversation centers on balancing data confidentiality with transparency needs, particularly when collecting data along industrial value chains from agricultural residue producers to biochar processors to end users. Perhaps most telling is Junginger-Gestrich’s unwavering commitment to scientific rigor over short-term economic gains: “We never had to trade off between rigor and allowing a not so good project on our platform for economic reasons. We always lean to the scientific and rigorous side.” This philosophy has guided Carbonfuture’s work with leading buyers like Microsoft, helping develop increasingly sophisticated approaches to carbon removal verification. While Junginger-Gestrich expresses concern about delayed emission reductions globally, he remains optimistic about carbon removal scaling: “I think we will be on the path to the gigatons by 2040 for sure.” His vision emphasizes ecosystem thinking over vertical integration, aiming to drive down costs while creating network effects that could accelerate the entire field. As governments worldwide grapple with climate policy, the monitoring, reporting, and verification systems companies like Carbonfuture are developing now may well determine the success of our collective effort to reverse climate change.

8 Ways to Reduce Your Impact Today

Published

on

With a full-time job, an active social life, and perhaps a kid or a pup to raise, it can be tough to fit in a commitment to the environment — especially if it seems to require added cost or responsibility.
Take heart, though, because there are many simple ways to reduce your impact on the planet that actually help you save money. Once you’re up to speed with the basics like changing your incandescent light bulbs to energy-efficient LEDs and shopping with reusable bags, check out these equally easy ways to simplify your go-go life.

1. Say ‘No’ to To-Go Waste

Even if you’re constantly on the run, it’s possible to reduce the amount of waste you generate by packing your own reusable mug, water bottle, food containers, and cutlery. The majority of restaurant to-go containers are still made from plastics that don’t recycle easily, so they’re used once and then thrown away. Each plastic cup, fork, straw, and clamshell box costs money, and you can be sure this cost is passed onto consumers — not to mention the environmental costs of all that plastic waste.

2. Water Well

Water is a precious resource, which is often a fact overlooked in developed countries where we can just turn on the tap and get clean, safe water. However, according to a 2025 WHO/UNICEF report, 2.1 billion people globally still lack access to safely managed drinking water, and the global potable water supply is under pressure from climate change and population growth. You can decrease your water consumption by following a few simple steps.

Flush and run sparingly: The average toilet uses between 1.6 and 5.5 gallons of water per flush. If you are already “letting it mellow,” save even more water by turning on the tap only when absolutely necessary. There’s no need for the water to run when brushing your teeth, washing your hands, or doing the dishes, for example.

Make sure it’s really dirty before washing: Clothing, dishes, and your body should undergo the wash and rinse cycle only when necessary. Use the same water glass all day, and wear those jeans more than once.

3. Hang It Out to Dry

Clothes dryers are among the most energy-intensive household appliances. Most of us are not willing to give up cold milk and crisp veggies from the fridge, but we can easily use the dryer less often, which can add up to significant savings of energy and money.

As an added bonus, letting your clothes air dry extends their usable lives (it is much less taxing on the stitching and fabric), it gives you a good excuse to get outside in nice weather, and line-dried laundry smells better too! If you live in a place where drying clothes outside right now would mean wearing duds that are cold and wet, consider using indoor drying racks to accomplish the same energy-free job.

4. Lights, Camera, Out!

Many electronic devices — such as phone and camera chargers, televisions, and computers — continue to draw energy even when in the “off” position. To avoid phantom power use, unplug such devices or plug everything into a power strip you can turn off when not in use. Encourage these same practices at your workplace. And no matter where you are, always turn off unnecessary lights.

5. Be a Wise Post-Consumer

In the digital age, many of us still rely on a steady stream of paper in our offices, kitchens, and bathrooms. Here are some easy suggestions for keeping more trees outside.

Print sparingly: When you do need to hold a document in your hand, be sure it has been printed and/or copied on both sides, and of course, be sure to recycle when done.

Buy the highest level of post-consumer, recycled paper: From toilet paper to notebooks, there is rarely a reason to use virgin paper. Look for the percentage on the packaging (such as products made with 100% recycled or 50% post-consumer materials), and also look for paper that is processed chlorine-free (PCF).

Class it up with cloth: Reusable napkins are not just for fancy dinner parties. They can be washed and reused indefinitely. The same goes for old T-shirts or towels, which can be repurposed as rags and used instead of disposable paper towels.

6. Resist the Urge to Splurge

A lack of excess cash can serve as a great excuse to reduce your consumption. Here are a few suggestions to help you consume less.

Take a consumption vacation: Consider taking the day or week off from making any new purchases, with the exception of necessities such as health products and food. By doing this, you’re not only saving money, but you’re also reducing the waste created throughout the life cycle of each new product, the packaging used, and the fuel consumed and produced in transporting products from the original resources to the manufacturer to your local store.

Buy nice, don’t buy twice: For necessities, make sure that you buy the highest quality, most energy-efficient, environmentally friendly model available within your budget. From appliances (Energy Star) to food (Local Harvest), there are low-impact alternatives for almost everything on the market.

7. Bid Your Car Adieu

We are a society that loves our cars, but there are many alternatives to a day spent solo in your gas-guzzling ride. Backing out of your car rut can also provide new opportunities to socialize and get some exercise.

Get on the bus: Many cities and towns have excellent public transportation systems that include buses, subways, and trains. You’ll be surprised at the new friends you make or the added reading time you find when not behind the wheel.

Carpool with friends or co-workers: Rideshare services now make it easier than ever to find a match. Uber’s UberX Share allows passengers traveling in the same direction to share a ride and reduce costs while cutting emissions. Lyft and Waze discontinued their shared rides programs in 2023.

Get on a bike or walk: While riding your bike or walking might take a little longer to reach your destination, the fresh air, reduced carbon emissions, and the exercise more than make up for the extra minutes.

Phone it in: Explore telecommuting or teleconferencing options with your employer to significantly reduce your daily commute. According to Global Workplace Analytics, a typical employer can save an average of $11,000 per half-time remote worker per year, while employees save between $2,000 and $6,500 annually from reduced commuting and related costs. Telecommuting just a few days a week will save you and your employer money.

8. Ban Planned Obsolescence

The more we view potential waste as building blocks for new products, the lower our overall impact will be. Granted, some products (“gum” comes to mind) are decidedly single-use items, but with a little creativity, many others can easily be creatively repurposed.
