Scientists sound the alarm over substances such as arsenic and lead contaminating soils and entering food systems
About one sixth of global cropland is contaminated by toxic heavy metals, researchers have estimated, with as many as 1.4 billion people living in high-risk areas worldwide.
Approximately 14 to 17% of cropland globally – roughly 242m hectares – is contaminated by at least one toxic metal such as arsenic, cadmium, cobalt, chromium, copper, nickel or lead, at levels that exceed agricultural and human health safety thresholds.

Online exhibition collects soundscapes from nature reserves and sites such as Machu Picchu and Taj Mahal

The Sonic Heritage project is a collection of 270 sounds from 68 countries, including from famous Unesco-designated sites such as Machu Picchu and the Taj Mahal, as well as natural landscapes such as the monarch butterfly sanctuary in El Rosario, Mexico and the Colombian Amazon.

Exclusive: Henry Dimbleby joins farmers in voicing fears of lower standards and a poor deal for British food producers
Britain’s rural communities could be “destroyed”, the former government food tsar has said, if ministers sign a US trade deal that undercuts British farming standards.
Ministers are working on a new trade deal with the US, after previous post-Brexit attempts stalled. Unpopular agreements signed at the time with Australia and New Zealand featured tariff-free access to beef and lamb and were accused of undercutting UK farmers, who are governed by higher welfare standards than their counterparts. Australia, in a trade deal signed by Liz Truss in late 2021 that came into effect in 2023, was given bespoke sanitary and phytosanitary (SPS) standards aimed to not be more “trade-restrictive than necessary to protect human life and health”.

Marylebone, London: These irrepressible birds can cheer up a motorway services or a railway platform. But their true home, for me, is on the pristine lawn of a cricket ground
Time rolls on, defying our efforts to slow it down for the enjoyable bits. I tick off the markers of spring’s progress. Far out west, in Ealing, a singing skylark evades detection in the boundless sky, its silver chain of sound offering no clues as to its whereabouts. In “leafy Barnes”, sand martins duck and dive in and out of their nesting burrows. And at Lord’s, the cricket season begins.
There is sun. There is a chill wind. There is a low hum of expectation. Lancashire are 143-2. Nearly everything is in place. All we need is a particular bird. As if summoned by the thought, it enters the scene. Flutter bounce flutter bounce land trot. Two rows in front of us, a member rejoices: “The wagtails are back!”

Nearly a quarter of shareholders vote against the chair, Helge Lund, as green protesters are blocked from entering
BP suffered an investor rebellion on Thursday after facing shareholders for the first time since abandoning its climate strategy at a meeting marred by protest.
About a quarter of shareholders voted against the chair, Helge Lund, at the company’s annual meeting in Sunbury-on-Thames, on the edges of London, which attracted protest from several green campaign groups.

Researchers analyse energy performance certificate data to identify areas with potentially high particle pollution
Burning wood at home adds more particle pollution to the UK’s air than all of the vehicles on its roads, but there is very little information on where this burning takes place and who is most affected.
To address this knowledge gap, researchers have produced the first high-resolution map of wood burning in England and Wales.

Thousands go to hospital with respiratory problems after massive dust cloud blows in from Saudi Arabia
Iraq was hit by its most severe sandstorm of 2025 this week, turning skies from blue to an orange haze. Visibility dropped to less than half a mile, causing travel disruptions, with two major airports halting flights, and streets in Basra, the largest city in southern Iraq, left deserted. Respiratory problems sent thousands to hospital. The storm also affected Kuwait, where wind gusts exceeded 50mph, and visibility in some areas was diminished to zero.
This massive dust cloud originated in Saudi Arabia before being blown into Iraq. While dust storms are common in Iraq, climate change is expected to intensify them across the region in the future, fuelled by desertification in Saudi Arabia and Syria.

Campaigners say authorities should be doing more to clean up waters around city of nearly 5 million people
On a clear summer’s day in Cape Town, the Milnerton Lagoon was serene, reflecting the bright blue sky and Table Mountain. But there was an unmistakable stench, and up close, the water was murky.
A few hundred metres away, adults and children played in the water as it flowed into Table Bay. On the boardwalk, a sign read: “Polluted water: for health reasons, swimming and recreational activities are at your own risk.”

Liberals in the US make up about 15% of the prepping scene and their numbers are growing. Their fears differ from their better-known rightwing counterparts – as do their methods
One afternoon in February, hoping to survive the apocalypse or at least avoid finding myself among its earliest victims, I logged on to an online course entitled Ruggedize Your Life: The Basics.
Some of my classmates had activated their cameras. I scrolled through the little windows, noting the alarmed faces, downcast in cold laptop light. There were dozens of us on the call, including a geophysicist, an actor, a retired financial adviser and a civil engineer. We all looked worried, and rightly so. The issue formerly known as climate change was now a polycrisiscalled climate collapse. H1N1 was busily jumping from birds to cows to people. And with each passing day, as Donald Trump went about gleefully dismantling state capacity, the promise of a competent government response to the next hurricane, wildfire, flood, pandemic, drought, mudslide, heatwave, financial meltdown, hailstorm or other calamity receded further from view.

Illegally diverted rivers, seawater and poorly managed building projects have polluted the Ciénaga Grande de Santa Marta. But the Unesco site has a vital role to play in fighting climate change
From the porch of her family home in Nueva Venecia, Magdalena, Yeidis Rodríguez Suárez watches the sunset. The view takes in the still waters of the Ciénaga Grande de Santa Marta wetlands. Pelicans dip their beaks into the lagoon, ripples breaking the glassy surface. Distant mangroves turn from green to deep purple in the dying light.
The 428,000-hectare (1,600 sq mile) expanse of lagoons, mangroves and marshes in Colombia has been a Unesco biosphere reserve since 2000. Yet, for Rodríguez, 27, the natural abundance is little more than an illusion.
