Are there clear polaroid glasses?
Most glasses (including most polaroid glasses) are clear. What would be the point of glasses if you can't see through them?
You probably want to know whether there are polaroid glasses that aren't dark.
No. There ain't no such animal. Daylight (like most light sources) includes photons that are polarized in all different directions. Polaroid glasses work by filtering out all but the ones that have approximately vertical polarization (as seen from the point of view of the person who is wearing the glasses). Since they're filtering out all of the photons that have less-desirable polarization, that means that not all of the photons are getting through, hence: Less Light---the glasses appear to be dark.
Polar bears feed mainly on ringed seals and bearded seals. Depending upon their location, they also eat harp and hooded seals and scavenge on carcasses of beluga whales, walruses, narwhals, and bowhead whales and fish.

Cold temperatures especially, Polar bears in the arctic are actually collapsing from heat exhaustion, also meat (preferably seal) space, water, shelter, (normal stuff) and to survive throughout years reproduction
How is the polor bear endangered?
Due to global warming, the polar ice caps are starting to melt. This means that the ice flows that polar bears live on would shrink, leaving them stranded in the water - the outcome being that they drown. Also because of this, they wouldn't be able to reproduce.
How many polar bears are left in the Yukon?
The Yukon groups show between 5,000 to 7,500. The total population of polar bears a few decades ago was under 1,000. Thankfully, these creatures are not endangered and their population is still growing.
What does the Svalbard polar bear warning sign look like?
The Svalbard polar bear warning sign looks like a signpost, but with a polar bear on it. Some signs show how the polar bear is on a black background of a triangular signpost with reddish edges.

How do polar bears regulate water balance?
Polar bears regulate water balance by homeostasis. They can also regulate their body temperature through thermo regulation, which is a form of homeostasis.

It allows them to go into a deep sleep so they use a minimal amount of energy. Then when there is more available food, they come out of their hibernation and start feeding to regain their energy reserves to do it again the next winter.
