Migratory species populations dwindling: report

From Morning Report, 8:26 am on 13 February 2024

Nearly all 97% of the world's listed migratory fish species are threatened with extinction, according to the first-ever report on the State of the World's Migratory Species.

That report finds the populations are dwindling for nearly half 44% of the planet's listed migratory species, while more than one-in-five of them are threatened with extinction.

The report says each year, billions of individual animals traverse distant continents, countries and habitats, performing crucial functions, such as the large-scale transfer of nutrients between environments.
