‘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

Vladimir Poutine a entériné, lundi 11 mars, la dénonciation de l’accord permettant depuis 1956 aux pêcheurs du Royaume-Uni d’opérer dans les eaux russes de la mer de Barents. Or, comme le pointe la presse, plusieurs centaines de milliers de tonnes de cabillaud ont été puisées par les Britanniques dans la région arctique l’an dernier.

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

L'Ouganda a lancé mardi ses premières activités de forage dans les champs pétroliers de Kingfisher, au lac Albert, accédant ainsi au rang de producteur de brut avec un mégaprojet critiqué par les défenseurs de l'environnement. Le président Yoweri Museveni a lancé "le début de la campagne de forage sur le champ pétrolier de Kingfisher (dans l'ouest de l'Ouganda, ndlr) qui devrait produire 40 000 barils de pétrole par jour" en 2025, a annoncé sur Twitter l'autorité ougandaise du pétrole.

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.
