This Is How Many Polar Bears Are Left in the World

Thanks to global warming, the polar bear population worldwide is shrinking.

Due to centuries of hunting practices and the destabilization of arctic habitats, there have been growing concerns about the future survival of polar bears. While hunting has long been an issue, global warming has done a number on polar bears' habitats in recent years, dramatically shrinking the polar bear population worldwide. In fact, the World Wildlife Fund (WWF) estimates that there are only 22,000 to 31,000 polar bears left in the world.

Since the 1960s, world leaders from the various habitats that polar bears call home—like the United States, Canada, Denmark, Norway, and Russia—have been making a conscious effort to protect the critically endangered and vulnerable polar bear populations. In 1973, they established a treaty called the International Agreement on the Conservation of Polar Bears, which strictly regulates commercial hunting.

But even with those practices in place, scientists are still worried about polar bear populations, particularly in Canada. According to the WWF, 60 to 80 percent of the world's polar bears reside there, and it's the only country where the population of polar bears is actively declining.

That said, conservationists' efforts have been somewhat successful. As of 2019, the WWF reports that "most of the world's 19 populations [of polar bears] have returned to healthy numbers." In fact, polar bears remain one of only a few large carnivores still found in their original habitats in roughly the same numbers.

But global warming puts polar bears in a dangerous situation. According to a 2018 study published in the journal Frontiers in Ecology and the Environment, very little of the ice in Northeast Canada and Northern Greenland will remain by 2040. "If the rate of sea ice loss and warming continues unmitigated, what is going to happen to polar bear habitat will exceed anything documented over the last million years," said marine biologist Kristin Laidre, the study's lead author.

Though it's hard to predict, scientists believe that approximately a third of the polar bear population will be eradicated by 2050.
