In the 4th century BC, Aristotle proposed that earthquakes were caused by winds trapped in subterranean caves. Small tremors were triggered by air pushing on the cavern roofs, large ones by air breaking the surface. We now know a good deal more about how and why earthquakes happen. Yet the most important part of the jigsaw – when they will happen – continues to confound us as much as it did the ancient Greeks

As the world turns away from fossil fuels, one question often overlooked is what to do with the thousands of ageing oil and gas platforms left vacant across the planet. When first built, little thought was given as to what to do with these hulks at the end of their productive lives. Only now, it seems, are major oil companies waking up to the reality that something needs to be done

Natural capital is a way to quantify the value of the world that nature provides for us – the air, soils, water, even recreational activity. Advocates say this is crucial if biodiversity is to have any clout in a world governed by raw economics. Others believe the concept merely turns the natural world into a commodity.

A tightening of restrictions on the insecticides known as neonicotinoids has brought hope that the decline in honey bees and wild pollinators can be reversed. Yet concerns are growing as to how new technology could radically change the landscape. Are we heading towards a world of ‘frankenbees’, in which gene-edited bees are resistant to pesticides and where only the rich can afford to pay for pollinated crops?

Few would argue with football’s position as the world’s number one sport. But as Mark Rowe discovers, this global popularity is masking a sinister underbelly with human traffickers using the bright lights of Europe’s elite clubs as a lure for Africa’s vulnerable youth

Palm oil is omnipresent in global consumption. But in many circles it is considered the scourge of the natural world, for the deforestation and habitat destruction which follows its production. Does this ubiquitous crop deserve to be treated with such disdain?

The UK appears to be embracing nuclear, a huge U-turn on government policy from just two years ago. Yet this seems to be going against the grain globally. Can nuclear help countries meet their commitments to the Paris treaty?

Cities the world over are struggling to improve air quality as scandals surrounding diesel car emissions come to light and the huge health costs of pollutants are better understood. Anthony Lambert reports

Diabetes is often thought of as a ‘western’ problem, one linked to the developed world’s overindulgence in fatty foods and chronic lack of physical activity. But with more than 400 million people affected globally, this disease is a global threat

For National Clean Air Day, Geographical brings together stories about air pollution and the kind of solutions needed to tackle it
