Here's why:
* Climate: Bears are generally adapted to colder climates with access to sufficient food sources like fish, berries, and nuts. These conditions are more prevalent in the northern hemisphere.
* Historical Distribution: Bears evolved in the northern hemisphere and have spread throughout the continents over millions of years. While some species like the spectacled bear and sun bear have adapted to tropical regions, the majority remain in northern latitudes.
While a few bear species do live south of the equator, their populations are significantly smaller than those found in the north.
