Au Sénégal, les ravages de la surpêche : «Cette usine de farine de poisson nous a gâté la mer»

Dans le port de Cayar, les ressources halieutiques se raréfient, notamment à cause de la surexploitation d’espèces locales pour fabriquer des aliments pour des poissons d’élevage
Au Sénégal, les ravages de la surpêche : «Cette usine de farine de poisson nous a gâté la mer»
A Cayar, port de pêche sénégalais où le poisson régit tout, les ressources halieutiques se raréfient. La faute à la surexploitation, qui menace notamment les espèces locales.

Mozambique: Le Royaume-Uni se retire d'un vaste projet gazier de TotalEnergie dans le pays
Le gouvernement britannique retire ses financements du projet GNL Mozambique. Une mauvaise nouvelle de plus pour le controversé projet de gaz naturel liquéfié porté par TotalEnergies. C'est un prêt d'un peu plus d'un milliard de dollars qui ne sera pas versé. Trop risqué, a estimé le gouvernement britannique ce 1ᵉʳ décembre.

Key electricity generation points for Q3 2025: The increase in renewable generation in China exceeded that of the rest of the work combined. The drop in Fossil Fuel use in China and India exceeded the increase in Fossil Fuel use for the rest of the world! 🧪🔌💡☀️💨💧🔋
The increase in Solar and Wind generation was dominated by China. The drop in Fossil Fuel generation in China and India dominated the rest of the world, leading to the global drop.
