Thousands of metres beneath the ocean surface lies an extraordinary world of ancient geological formations, unusual organisms and ecosystems that scientists are only beginning to understand.  Now, companies and governments are preparing to extract valuable minerals from the seabed. The potential rewards are enormous. So are the risks. Could humanity be about to destroy one of Earth's last great wildernesses in pursuit of the materials needed to power its technological future? An industrial revolution beneath the waves Imagine an industrial mining operation taking place more than four kilometres beneath the ocean surface. There is no sunlight. Temperatures are close to freezing. The pressure is hundreds of times greater than at sea level. Yet, scattered across the vast darkness of the seabed, lie millions of mineral-rich rocks containing metals increasingly important to modern civilisation. These are polymetallic nodules. They can contain manganese, nickel, copper and cobalt, among ...

Artificial intelligence is transforming the world, but behind the promises of technological progress lies a rapidly expanding demand for land, electricity and water.  Across Britain, communities are beginning to question whether the price of the AI revolution is being paid by the wrong people. A technological revolution with a physical footprint Artificial intelligence increasingly appears to exist everywhere and nowhere. It writes articles, generates images, analyses medical information, assists scientific research and influences decisions across business, government and everyday life.  Much of this activity takes place behind screens, creating the impression that the digital revolution has relatively little physical presence. But AI has a substantial physical footprint. Behind every sophisticated AI model sits an enormous network of computer processors, storage equipment, cooling systems, electricity infrastructure and buildings.  These facilities are known as data cent...

For generations, Lough Neagh was simply part of the landscape of Northern Ireland: a vast freshwater lake supporting fishing, farming, wildlife, recreation and communities around its shores. Then, in the summer of 2023, something became impossible to ignore. Large areas of the lake turned green. Thick surface scums accumulated around marinas, jetties and lock gates. Images of vivid green water spread rapidly, and what might once have been regarded as an occasional natural phenomenon became a national environmental story. But the colour was only the visible part of a much larger problem. Beneath the surface was a lake receiving enormous quantities of nutrients, experiencing warmer conditions, containing an invasive species capable of altering its food web — and accumulating pollutants from a catchment covering thousands of square kilometres. The phenomenon did not end in 2023. A significant bloom returned in 2025. As of 2026, scientists and government agencies are still trying to determ...
