Why plastic bottles now have their caps attached

You may have bought a drink recently and noticed something odd: the once removable cap is now tethered to the bottle by a small strip of plastic. An EU directive was enacted in July, requiring that all single-use bottles have caps that remain attached. This is one of several policies designed to limit the amount of plastic litter –… Continue reading Why plastic bottles now have their caps attached

New technologies could help destroy persistent ‘forever chemicals’

Scientists and engineers are developing new ways to destroy per- and poly-fluoroalkyl substances (PFAS) efficiently and sustainably. This class of chemicals is known as “forever chemicals” because PFAS persist and accumulate in the environment, animals and our bodies. PFAS have been used for decades to make everything from firefighting foam, packaging, waterproof clothes and non-stick frying pan coatings.… Continue reading New technologies could help destroy persistent ‘forever chemicals’

Sharks in Rio de Janeiro test positive for cocaine

Sharks off the coast of Brazil’s party city Rio de Janeiro have tested positive for cocaine. The predators were consuming the potent stimulant due to its continuous release from inadequate sewage treatment facilities and clandestine refining operations, scientists wrote in a study published in Science of The Total Environment.

The fight against the climate crisis must not increase inequalities

As the impact of climate change on communities increases, researchers are concerned about growing inequalities. The most recent report by the Intergovernmental Panel on Climate Change (IPCC) stresses the importance of one aspect that is too often neglected by local action on climate change: considering the question of inequalities. Studies show that the people, communities… Continue reading The fight against the climate crisis must not increase inequalities

How air quality has changed in over 100 countries around the world since 1850

Air pollution is an unseen menace that poses a major threat to human health and the climate. We have created the air quality stripes, a visual tool that captures global air pollution trends, to bring this hidden threat into sharp focus. Inspired by professor of climate science Ed Hawkins’ climate warming stripes, the air quality… Continue reading How air quality has changed in over 100 countries around the world since 1850

Britain’s ‘broken’ water system: a history of death, denial and stomach aches

In the spring of 2024, residents of the south Devon harbour town of Brixham kept falling ill. Their symptoms – including “awful stomach complaints, bad diarrhoea and severe headaches” – went on for weeks. A retired GP who ventured to the pub after finally recovering from the illness recalled that, when someone asked those present to “raise… Continue reading Britain’s ‘broken’ water system: a history of death, denial and stomach aches

Fast fashion: why your online returns may end up in landfill – and what can be done about it

Fashion has a notorious environmental footprint, accounting for up to 10% of global carbon dioxide output. This is exacerbated by a fast fashion business model which encourages the frequent purchase of low-priced and non-durable items. Around 30% of online purchases are subsequently returned, much of which goes to landfill. In 2020, an estimated 2.6 million tonnes of returns were disposed of… Continue reading Fast fashion: why your online returns may end up in landfill – and what can be done about it

Are emails bad for the planet?

To much text messaging

The idea that sending less emails would have a significant impact on the environment was popularised by the book ‘How Bad Are Bananas? The Carbon Footprint of Everything.’ This, released in 2020, was by Professor Mike Berners-Lee, a respected authority on the topic.  Professor Berners-Lee mentioned that every email creates something from 0.3 to 50… Continue reading Are emails bad for the planet?

Climate change is making hay fever worse

Note: hay fever has no connection to hay. In the 1800s, people believed freshly cut hay caused it, hence the name. The true cause—pollen—was discovered in 1859 by British scientist Charles Blackley. Climate change affects not only the health of the planet but also that of people, worsening conditions such as hay fever, formally known… Continue reading Climate change is making hay fever worse
