‘Catastrophic’ global decline due to dams, mining, diverting water and pollution threatens humans and ecosystems, study warns

The law will come into force in national parks within two years and in all of the country’s marine protected areas by 2030

We are a species that is superb at killing, says veteran oceanographer, who calls for us to stop treating fish like crops and give them the respect they deserve

At the Hay Festival, BBC Future assembled a panel of thinkers to discuss one of the most pressing questions of our time: how to tackle society’s habit of “short-termism”.

Behind the headlines about billionaire jaunts into space, there's a deeper motivation – the belief that spreading into the cosmos will save humanity's future. How did this idea emerge?

A community of Indigenous peoples worried that mercury used by gold miners was contaminating the fish they eat. So they created a DIY team to find out more.

Lost nets, lines and hooks trap wildlife for years as they float in the ocean, sink to the bottom or are washed ashore

Atmospheric soot loadings from nuclear weapon detonation would cause disruptions to the Earth’s climate, limiting terrestrial and aquatic food production. Here, we use climate, crop and fishery models to estimate the impacts arising from six scenarios of stratospheric soot injection, predicting the total food calories available in each nation post-war after stored food is consumed. In quantifying impacts away from target areas, we demonstrate that soot injections larger than 5 Tg would lead to mass food shortages, and livestock and aquatic food production would be unable to compensate for reduced crop output, in almost all countries. Adaptation measures such as food waste reduction would have limited impact on increasing available calories. We estimate more than 2 billion people could die from nuclear war between India and Pakistan, and more than 5 billion could die from a war between the United States and Russia—underlining the importance of global cooperation in preventing nuclear war.

We have here (in the Baltic Sea, about half a million tonnes of conventional munitions and about 40,000 tonnes of chemical weapons. Some of the conventional munitions are armed and may explode if moved. As for poisoning people and fish, we don`t have enough data to speak of probability. However, the bombs leak poisonous substances, the seabed is contaminated in their immediate vicinity (up to 250 m).

Restaurant menus across the West Coast of Canada will soon see an influx of squid and sardine dishes, while the popular sockeye salmon makes a slow exit. As it turns out, climate change may have something to do with this.

The ivory-billed woodpecker, along with 22 other species of birds, fish, mussels and other wildlife, is set to be declared extinct and removed from the endangered species list, US federal wildlife officials announced Wednesday.

The world’s coral reef cover has halved since the 1950s, ravaged by global heating, overfishing, pollution and habitat destruction, according to an analysis of thousands of reef surveys. From the 1,430-mile (2,300km) Great Barrier Reef in Australia to the Saya de Malha Bank in the Indian Ocean, coral reefs and the diversity of fish species they support are in steep decline, a trend that is projected to continue as the planet continues to heat in the 21st century.

There are significant causes for concern regarding the content of oxygen in the ocean, however. The ocean’s O2 reservoir is vulnerable because it holds less than 1% of the oxygen stored in the atmosphere. In particular, ocean regions with very low or absent oxygen, referred to as oxygen minimum zones, expand as the planet warms,

Salmon in the Columbia River were exposed to unlivable water temperatures that caused them to break out in angry red lesions and white fungus in the wake of the Pacific north-west’s record-shattering heatwave, according to a conservation group that has documented the disturbing sight.
