More than a quarter of species are at risk of extinction, new report says

(CNN) - A new report says melting sea ice and deforestation are threatening the survival of many species.

The latest Red List of Threatened Species assessment released Friday shows that more than a quarter of all animals, plants and fungi assessed are at risk.

It found three species of Arctic seals now face extinction because of climate change, and more than half of the world’s birds are in decline due to habitat loss.

But in one bright spot, researchers said the green sea turtle population is rebounding thanks to decades of conservation efforts.

The Red List database is updated regularly by the International Union for Conservation of Nature.

Its latest endangered list includes more than 170,000 species.
