100 people die by bears every year.
* 17 polar bears die every year acording to average
Wild moon bears are very lucky, because when they are captured by the Chinese... Chinese people capture moon bears, and put them in tiny cages. Their stomachs are opened up without an anesthetic, and a kind of "thing" takes their bile out of them. They have to live like this for years of their life, in unspeakable pain, until they finally die horribly. (I am not insulting the Chinese, I am just giving you information.)
yes polar bears can die
People are putting tubes in their stomach and taking out the bile for medicines (yuck). Even though we can survive if we didn't have Bile, for some randon reason moon bears can't. So of course no one thinks about the moon bears and lets them die afterwards and gets some more (completely unfair).
We don't know. Counting the population of living bears is extremely difficult, without trying to predict an exact number of how many will die.
plants and animals
All of them. Just like all other creatures, eventually we die.
There are many stores which sell personalized teddy bears. You are best recommended to shop online at such stores as Mandys Moon and Bears4U where you can customize your bear.
