They aren't suppose to be treated like pets. That is the value scientists carry in assessing a species ability to return from any endangered or threatened status.
It is coming summer and the first year of cubs. These cubs are not going to survive as they aren't learning their natural hunting skills. There will be a need for wildlife management to reassess the recovery plan for these giant marine mammals.
The loss of ice in the Arctic Ocean is most probably causing a collapse of the ecosystem. I wouldn't doubt the seals have declining numbers, too. Last year we witnessed walruses moving to land as well. Even the Native Americans would be threatened if they didn't have access to other food sources such as a grocery store. Even then they need a source of income. The Native Americans in the USA aren't the only native people in the region. There are other groups throughout the Arctic region.
The world’s oceans are in trouble. (click here) Every day, 22 million tons of carbon dioxide from factories, cars, power plants and other human sources are absorbed by the world’s oceans.
The result? A frightening phenomenon that's making seawater more acidic, spelling disaster for many marine animals, from plankton and coral up the food chain to sea stars, salmon, sea otters, whales — and ultimately people, who rely on oceans for food....
The phytoplankton are at the center of the ocean food chain, the Arctic Ocean is no different. The phytoplankton are single cells organisms. The change in pH will effect their existence. Is is the global phytoplankton that produce the majority of Earth's oxygen as well.

ANCHORAGE, Alaska — A group of researchers (click here) say polar bears forced off melting sea ice will not find enough food to replace their current diet of fat-laden marine mammals such as seals, a conclusion that contradicts studies indicating that bears may be benefiting from bird eggs, berries and other land food sources.
Few bears are using land food and what they find can’t replace lipid-rich ringed or bearded seals, said Karyn Rode, a U.S. Geological Survey research wildlife biologist and lead author of the review paper published Wednesday in the journal, Frontiers in Ecology and the Environment.
The paper by federal and academic researchers reviews current polar bear research. It’s aimed at recent research documenting bears feeding on land and suggestions that those foods are becoming more important for them, which could increase their chance for survival as summer sea ice recedes, preventing seal hunting....
