If global warming continues, and there are no signs yet of it even even slowing, then there is a strong possibility that polar bears will become extinct. If their habitat, the sea ice, disappears, they will be forced onto land to compete with other bears for food. They may begin mating with land bears and the polar bear may disappear.
Polar bears are not close to extinction now, there are still probably several thousands of them left, though it's difficult to count their numbers with any accuracy.
However, polar bears are in danger, because their habitat, the Arctic sea ice, is shrinking because of global warming. Bears feed mostly on seals which they catch on the sea ice, and rely on vast amounts of seal fat eaten from late April till mid-July to last them through the food-free summers.
Because of global warming, the sea ice re-forms later each year, so polar bears have to wait longer before they can start to hunt again.
Weakened female bears have fewer cubs, and this is the problem.

∙ 13y agopolar bears are becoming extinct by hunters and global warming
They are not becoming extinct. They have grown in numbers from a low of 800 to about 25,000 to 27,000 today. The issue was over hunting.

∙ 13y agoNo, not likely. Although thought to be an endangered species by many, the polar bear is listed as vulnerable, and the population is actually going through a slight increase.

What math used in Mechanical Engineering?
First off, the question should be either "What math is used in Mechanical Engineering? or What is the highest level of math someone needs to take in order to become a Mechanical Engineer?" Most college programs require through Differential Equations to earn a BS degree in ME. This means you would need to take Calculus 1, 2, and 3, Linear Algebra, and Differential Equations once you get to college. It is assumed that most students going into engineering will have no less than Pre-Calculus before entering college while most will have taken Calculus. Now each college has different requirements for fulfilling the math requirements for an engineering program. I know from my experience, Georgia Tech teaches math differently than most colleges because they combine Calc 1-3 and Linear Algebra into just 3 courses instead of 4. My suggestion is look at the program requirements at the school you are interested in first. Second, evaluate whether you feel that you can learn the math. For those who struggle with math, if you really want to be an engineer, I suggest going to a smaller school where the class size will be smaller. This will have better student/teacher interaction so you can get more help.

because sun bears are so use to being warm all year and polar bears can adapt better ( i reALLY DONT NO ?)

How much do polar bears sleep?
With the exception of pregnant females, polar bears do not hibernate. Instead adult male polar bears and non-pregnant females remain active throughout the year. They nap during the day and sleep 7 to 8 hours a night.
