The polar bear is an animal that has inhabited the North Pole for thousands of years. Its adaptability and majesty have made it an iconic symbol of Arctic wildlife. However, The arrival of the Industrial Revolution has marked a drastic turn in its history, turning the polar bear into an emblem of modern climate change. Throughout history, climates have changed, but humans have accelerated this process at an alarming rate. In their constant pursuit of progress, they have devastated entire habitats and brought many species to the brink of extinction. Today, the polar bear faces an imminent threat of extinction.
A Sea Legacy team, led by renowned photographers and conservationists Paul Nicklen and Cristina Mittermeier, witnessed a heartbreaking scene at an abandoned Inuit camp on Baffin Island, Canada's largest and the fifth largest in the world: An adult polar bear, with no visible injuries, was dangerously thin and was dying before their eyes. But what is the reason behind this tragedy?
Although climate change cannot be directly blamed in every case, the reality is that an increasing number of polar bears are dying in similar circumstances due to rising temperatures affecting their habitat. The melting season has come earlier, forcing these animals to travel long distances to find food. The scarcity of sea ice, which is vital for their hunting and mobility, is drastically affecting their feeding habits and ability to survive.
Is it possible to prevent the deaths of more polar bears? Definitely. There are measures that we can all takeReforestation, pollution control, the use of clean energy, and environmental protection are just a few actions we could implement. But the question we must ask ourselves is: Are world leaders really interested in doing something for the planet?
Humanity is capable of being cruel to nature, but it also has the potential to care for it. If the majority of the population united in collective action, we could solve these problems in a few years.
Polar bears, or Ursus maritimus, are marine mammals that depend almost exclusively on sea ice for food. This ice is crucial, as it allows them to hunt seals, their main food source. The lack of ice not only affects their hunting ability but also their overall health. A recent study indicates that Arctic sea ice is shrinking by at least 13% per decade, and as a result, polar bears are forced to swim long distances in search of food. This leads to increased energy loss and malnutrition. For more information on this problem, we recommend reading our article on The melting of the Arctic and its impact on the diet of polar bears.
The situation is critical. As the global temperatures rise, so does the length of the ice-free period, causing polar bears to have less time to eat before winter arrives. In some areas, conflicts between polar bears and humans have been reported, as the bears seek food in human settlements due to the scarcity of prey in their natural habitat.
Climate change is not only affecting polar bears, but is also disrupting the Arctic food web as a whole. The decline in sea ice impacts the seal population, which is the bears' main prey. As the Arctic Ocean warms, phytoplankton and zooplankton, essential to the food chain, are also affected. This limits the food supply and creates fiercer competition between polar bears and other Arctic predators, such as the Arctic fox.

In the face of the crisis, several strategies are being explored to help polar bears adapt. Research has shown that some bears have begun to shift their diet, seeking out terrestrial foods such as berries and small mammals. However, This type of food is not enough to meet your energy needs, and many of these bears are experiencing a decrease in their body mass. It is estimated that during the summer, polar bears can lose between 400 grams and 1.7 kilograms of body mass per day, depending on their access to food.

Hunting prey on land is also less efficient, and polar bears often have to swim long distances to reach new hunting grounds, which increases their energy expenditure. The loss of ice and the need to adapt to new conditions are causing a significant decline in the bear population.
The main cause of climate change is greenhouse gas emissionA major contributor to these emissions is industrial animal agriculture, which accounts for more than 14% of global emissions. Eliminating harmful agricultural practices and adopting more sustainable methods is crucial if we want to ensure a future for polar bears and other endangered animals. To better understand the impact of climate change on wildlife, see our article on animals in danger of extinction due to global warming.
Preserving forests, reducing the use of polluting products, and shifting toward cleaner energy are just some of the solutions we can implement as individuals. If each of us does our part, we can help combat the climate crisis and protect polar bear habitat.
Polar bears are not only important for the balance of the Arctic ecosystem, but their survival also has cultural and economic implications for the indigenous communities that depend on them. Therefore, the conservation of this species is not only an ecological imperative, but also a moral duty.
