ASIA-PACIFIC

* Unless something is done, fish stocks will run out by 2048.

* Up to 90 percent of corals will be severely degraded by 2050 as a result of climate change.

* As much as 45 percent of biodiversity could be lost by 2050

EUROPE AND CENTRAL ASIA

* Soil erosion has affected 25 percent of agricultural land in the European Union, and 23 percent in Central Asia.

* More than a quarter of marine fish species have declining populations.

* 42 percent of known terrestrial animal and plant spaecies have declined in population size over the last decade.

AMERICAS

* With 13 percent of the world's population, the region accounts for about a quarter of the total impact on global biodiversity.

* Just under a quarter of species assessed are at risk of extinction.

AFRICA

* Climate change could result in the loss of more than half of Africa's birds and mammals by 2100.

* About 500,000 square kilometers (193,000 square miles) of soil has been degraded by human made crises.

GLOBALLY

* Two species of vertebrates, animals with a backbone, have gone extinct every year, on average, for the past century.

* Scientists say Earth is undergoing a "mass extinction event," the first since the dinosaurs disappeared about 65 million years ago, and only the sixth in the last half-billion years.

* About 41 percent of amphibian species and more than a quarter of mammals are threatened with extinction.

* The global populations of 3,706 monitored vertebrate species -- fish, birds, mammals, amphibians, and reptiles.

* declined by nearly 60 percent from 1970 to 2012.
