Polar Bear Slate

The slate stickers "endangered species" are printed on a medium not containing petroleum derivatives (biopolymer-based potato starch).

The polar bear is threatened by global warming
which has the effect of melting ice at the poles.

In addition, toxic substances prevalent in the sea are absorbed by small marine organisms consumed by fish, themselves consumed by seals, the latter being the prey of bears. Bears therefore accumulate the toxic substances of all these animals.
