Scientists say most polar bears could disappear by the end of the century and global warming is what is causing it, and polar bear populations will be very little by 2080, if we don't act now.

Polar bears rely on ice to find food. Without ice, the bears must roam on the shore, where they have to stay away from their food source. 

There’s not enough food on land to give to the polar bear’s population. That means they could starve. Mother bears may not be fat enough to produce milk for their cubs, which is starting a fast decrease in the species.Their loss could break a chain in the ecosystem.

On June 19th, a new global treaty to protect and sustainably use marine biodiversity in areas beyond coutry boundaries was signed and 200 countries signed COP15 to stop nature loss by 2030.

⅔ of the world’s oceans are outside coastal state zones but areas beyond restrictions are vulnerable to  lots of threats, including pollution, the results of changing climates and much more.

The Arctic is changing faster than any. This is caught by satellites that monitor the Earth. The satellites also caught the snow melting faster in spring and decreasing in the northern hemisphere.

Beneath the snow, permafrost stays frozen for the whole year but due to warming, it is decreasing rapidly.

Along the arctic shoreline, the ground temperatures rise 1 degree celsius per decade. That might not sound like a lot, but small changes lead to big problems.
