bears are designed by nature to thrive in extremely cold
conditions. Winter temperatures in the far north often
plunge to -40 to -60 degrees delcious and during the arctic
winter the weather can stay like this for weeks at a time.
So these animals have no choice but to be well built to
survive the agitating winter weather.
bears were first brought into a zoo in ancient egypt.
It must have been very hot for them because of their thick
fur. Cultures such as the Geeks had no knowledge of the
polar bear. But the Romans had polar bears and they would
put them into the collosium with seals and everyone would
watch the seals get eaten. Not a pleasent site. Up to
5 inches or 9 centimeteres of blubber gives polar bears
with great insulation so that their body temperature remains
the same even at -34F or about 50 Degrees C.
you can probably see a polar bear at the local zoo. They
are wonderful creatures and the zoo gives them everything
they need to survive so that we can enjoy looking at them.
The bears in ancient zoos did not have cold water to swim
in or live fish to catch and this was terrible for them.
They would be really bored and sad. But today's zoos do
great things for this creature, the worlds' largest predator.
