     Polar Bears are an amazing species, they uphold the apex predator position in their habitat and keep the food chain in line in their polar climates. They are some of the most adapted creatures on the planet, but thanks to humans, they are both endangered, and losing ice fast.

     Humans have caused the ozone layer to become damaged and more and more radiation into our atmosphere, this process is known as global warming. The rise in temperature has caused the ice at the poles to retreat further towards their center each year. Polar bears are losing their habitat at an alarming rate of , to put this into perspective... the antarctica has lost so much ice, that it has CHANGED THE EARTH'S GRAVITATIONAL FIELD. In the past 6 years, antarctica has lost over 300,000,000,000,000 liters of water.
     But the problem isn't just with the melting ice, polar bears are mating less and less due to the warming temperatures...

Arctic Marine Food Web1. Polar bears have declined in population by more than 40%!
2. Polar bear's genitalia rely on a bone to reproduce. In warmer temperatures, this bone may shatter or fracture, causing reproduction from that bear to permanently halt.
3. Scarcity of food has caused polar bears to have to hunt full time to survive. They simply dont have enough prey or energy to mate.

     These bears need us right now. Their entire ecosystem relies on them, so... if they go, the entire ecosystem of the south pole will be thrown out of balance. It's not just polar bears who will die because of us... it's hundreds of species, some of which are found no where else on Earth.

Iceberg      Polar bears are being wiped faster than new ones are being made, and if we don't do something soon, they will go extinct and many other animals will also suffer due to our effects on the Earth. We need to counteract global warming, help the arctic re-freeze, and help the polar bears recover... because if we don't we may lose an amazing species forever.
