Dangers Facing The Bear Population

Looking at the list, you will notice that a large number of bear species have gone extinct. Those that still exist have small and ever-dwindling populations. Without human intervention, these bears will also go extinct.

To save these majestic animals, we need to understand the source of their issues, so let us break this down; 

One of the biggest concerns for bear populations is global warming. Global warming has the most significant effect on polar bears. 

These predators need the ice caps to hunt for food; global warming is causing these ice caps to melt. 

These changes make it hard for the bears to find food, and the population suffers more each year. The increasing temperatures change the ecosystem and migration patterns of bear food, making it harder to thrive. 

Bears hibernate, so damaging their food sources is devastating to the population. Aside from this, bears get killed by hunters for their fur, which also ruins the population. Pollution exposes bears to more pathogens than they can handle.

It is the responsibility of every citizen to step up and protect these animals. We need to check our pollution levels and reduce our carbon footprint to give bears and other animals a chance at survival.


There are many bear species on the planet currently, and adding those that went extinct makes this list more impressive. Bears vary in size even in the same species; the difference is primarily due to gender and genetics.

In most species, females are smaller than males, while others have the exact sizes. The bear population is in danger, and it is primarily because of human activity. Global warming is destroying food resources for most animals, including bears.
