Wildlife experts are worried about the number of bears left in the world.
The World Conservation Union says at least six of the world's eight bear species are in real danger.
The giant panda is the world's most endangered species of bear, but others like the polar bear and sloth bear are also under threat.
Researchers say it's mainly due to the forests where they live being cut down, but poaching and climate change are said to be putting them at risk.
Wildlife experts say urgent action is needed to protect all bears from the impact of humans.
