The International Union for Conservation of Nature (IUCN) has reported that the populations of four endangered tuna species are increasing, attributed to the global tuna catch quota system. The IUCN also warned that 37% of all shark and stingray fish species are at risk of extinction due to overfishing. The union urged for countries to work towards sustainable fisheries and conserve biodiversity. French President Emmanuel Macron called for measures to reduce pesticide use and plastic pollution, with plans to announce a detailed suspension schedule in the first half of 2022.
