Economic growth and the search for abundance

A moment halfway through Ezra Klein’s and Derek Thompson’s recent book Abundance reveals something of their approach to building a net zero world. In 2023 a gasoline lorry exploded, causing Philadelphia’s I-95 bridge to collapse; Governor Josh Shapiro waived all the usual rules and regulations for public works so it could be rebuilt in record time. The project was of great benefit to the community. But during the works, the state secretary of transportation recalls encountering two workers using...

Book review: The Last Drop: Solving the World’s Water Crisis by Tim Smedley — how Britain’s taps could run dry

I read most of Tim Smedley’s book about the world’s impending water shortage while wallowing in the bath. It’s where I do much of my reading, happily turning the pages for hours until my flatmates begin to hammer on the door of our only bathroom. From that vantage, the thesis of The Last Drop: Solving the World’s Water Crisis felt utterly improbable. How can we be on the brink of a water shortage, not only elsewhere but in grey and soggy Britain too, when it flows so easily and cheaply...

The Guardian Long Read: ‘Drought is... the next pandemic’

During the summer months in the Oxfordshire town where I live, I go swimming in the nearby 50-metre lido. With my inelegantly slow breaststroke, from time to time I accidentally gulp some of the pool’s opulent, chlorine-clean 5.9m litres of water. I stand a bottle of water at the end of the lane, to drink from halfway through my swim. I normally have a shower afterwards, even if I’ve showered that morning. I live a wet, drenched, quenched existence. But, as I discovered, this won’t last. I am living on borrowed time and borrowed water.

Is air pollution causing us to lose our sense of smell?

For many people, a bout of Covid-19 gave a first taste (or rather a lack of it) of what it is like to lose their sense of smell. Known as "anosmia", loss of smell can have a substantial effect on our overall wellbeing and quality of life. But while a sudden respiratory infection might lead to a temporary loss of this important sense, your sense of smell may well have been gradually eroding away for years due to something else – air pollution.

The pollution causing harmful algal blooms

It is the "smell of decay and death", says Beth Stauffer, from the University of Louisiana. "It has a physical presence. This layer of very striking greens and blueish greens…when you put your paddle in it, you can feel it."

She's describing the harmful algal blooms (HABs) that used to be more associated with marine environments. But in recent years they've been moving further inland and affecting freshwater systems, too. And scientists such as Stauffer are trying to find out why.
