Ahead of International Polar Bear Day (27 February) this year, polar bear habitat is as abundant as it has been for decades. This is a tough time for polar bears, many of which will be finding it hard to find seals to eat, as newborn seals won’t be an available food resource for about a month in most areas. Thin and hungry bears are dangerous.

Keeping in mind that dark blue and purple areas (first year ice) are the best hunting habitat for polar bears because they are the best habitat for seals:
