A shocking new report on global biodiversity is detailing what it calls "a catastrophic decline" in wildlife populations ahead of a major international conference on biodiversity.
Freshwater species are beginning to decline at twice the rate of species that live on land or in the ocean. This rapid loss has already placed 27% of 29,500 species dependent on fresh water on the IUCN Red List. [100] Global populations of freshwater fish are collapsing due to water pollution and overfishing. Migratory fish populations have ...
