How climate change threatens polar bears and how conscious travel can help

Climate change poses a serious threat to the polar bear's habitat, and conscious travel can make an important contribution to protecting these majestic animals and their Arctic home. But how exactly can conscious travel help in the context of climate change and polar bears? Read on to find out more!

Dear ice cream pioneers,

My name is Patricia, and I am Head of Sustainability & Nature Positive Strategy at inventia. You will find regular posts from me on our blog – covering topics such as sustainability, nature conservation, and responsible travel. It is very important to me to share this knowledge – because I am convinced that every trip has the potential to leave something good behind. If we travel with our eyes open, we can make a difference.

Last week, I had the opportunity to participate in a webinar hosted by Polar Bears International(PBI)—an organization dedicated to protecting polar bears. As a leading voice in global polar bear conservation, PBI is committed not only to preserving these fascinating animals, but also to preserving their dwindling habitat, the Arctic sea ice. Below, I share the key takeaways and insights from the webinar—in the hope that they will move and inspire you as much as they did me.

Life on thin ice: How climate change is pulling the rug out from under polar bearsunder their paws

Polar bears are perfectly adapted to life in the ice—butthis veryhabitat is literally melting away beneath their paws. The dramatic decline in sea ice due to climate change poses the greatest threat to their survival. Unlike many other species, polar bears cannot adapt to living on land permanently— their entire existence is tied to the Arctic ecosystem. 

A central element of this habitat is sea ice—not only because it provides a surface for movement, but above all because it is a hunting ground. Polar bears are large animals with enormous energy requirements. Their most important source of food is seals—and they catch them exclusively on the ice. In open water, seals are simply too fast.

So what happens when the ice disappears? Especially in regions such as Hudson Bay, where the sea ice melts completely in summer, polar bears are forced to spend several months on land—without access to their main food source. During this time, they eat little or nothing and live exclusively on their fat reserves.

They are perfectly equipped for this from an evolutionary perspective: polar bears are true specialists when it comes to fat. Their digestive system is designed to utilize the fat-rich blubber layer of seals particularly efficiently. These fat reserves not only provide them with energy for hunting, but also serve as a vital supply during the long fasting period on land—a phase that is becoming increasingly longer due to climate change.

The longer polar bears are forced to remain on land, the more difficult it becomes for them to meet their enormous energy requirements. Although some animals show a certain degree of adaptability and resort to seabird eggs or reindeer in times of scarcity, these alternatives are far from sufficient. To compensate for the loss of energy-rich seal fat, they would have to consume disproportionately large amounts of it – a clear loss in terms of calorie balance.

Polar Bears International therefore emphasizes that what appears to be adaptation is in fact a short-term survival mode—not a sustainable solution for the future. Protecting sea ice is therefore not only important—it is essential for survival.

In addition to climate change, other, often less obvious factors are also affecting polar bears: pollutants enter the Arctic via the air and oceans and accumulate in the food chain – with potential consequences for the animals' reproduction and health. As temperatures rise, new pathogens and parasites are migrating north, placing additional strain on the bears' immune systems. Growing economic activities such as shipping, tourism, and raw material extraction also pose risks – for example, through noise, pollution, or the disturbance of sensitive refuges.

The growing conflict between humans and bears is particularly worrying: in search of food, polar bears are increasingly venturing into settlements – often with fatal consequences for the animals, further weakening populations that are already under pressure.

Hunting, once one of the greatest threats, is now strictly regulated in many places and remains culturally and economically important for indigenous communities. However, to ensure that this remains the case in the future, clear rules, reliable scientific foundations, and international cooperation are needed to ensure that populations are preserved in the long term.

Act now, think long term: How we can save the polar bears' habitat

To protect polar bears, a plan with two time horizons is needed: now and in the long term. 

In the short term, every step that directly addresses the dangers counts— especially where humans and polar bears are coming into closer contact. One example is the "Detect to Protect" radar: it detects bears approaching human settlements at an early stage and enables timely warnings to be issued. This helps to avoid dangerous encounters and protect both humans and animals.

The safe disposal of waste is just as important, because food scraps or openly stored garbage are like an invitation to polar bears. Clean storage or special containers can prevent bears from coming into villages in the first place. Both are simple but effective measures to make coexistence safer—for everyone involved.

In the long term, however, there is no way around combating climate change. Without sea ice, polar bears will lose their livelihood. This requires international cooperation and political decisions that effectively reduce greenhouse gas emissions—the most important step toward permanently preserving the Arctic habitat.

Why conscious travel matters

While climate change threatens polar bears in their natural habitat, conscious travel can offer a direct solution. Contrary to many preconceptions, Polar Bears International does not see conscious travel as a problem—but as part of the solution.

Anyone who has ever encountered a polar bear in the wild will never forget the experience. Such encounters get under your skin. They create closeness, respect, and a deep emotional bond. And this is precisely the key: people who form a connection with nature are willing to work to protect it.

Many guests returning from a trip to the Arctic not only talk about spectacular landscapes—they also recount their first encounter with a polar bear, the breath of the wilderness, and the feeling of being part of something bigger. This experience stays with them. And it continues to have an impact: among their friends, on social media, and in their everyday lives.

This creates ambassadors for nature conservation who share their knowledge, inspire others and, in the best case scenario, take action themselves. Financially, too: tourism brings important funds for research and conservation projects to the region. This is an aspect that is often forgotten, but it is crucial when it comes to the long-term financing of organizations such as Polar Bears International.

The challenges are complex, but Polar Bears International makes it clear: protection starts small— with every conversation, every decision, every journey. And yes, the major decisions in climate policy are crucial. But they need tailwinds—from science, from practice, from the center of society.

If you have read this far, then you already carry something important within you: the desire to perceive the world consciously—and to take responsibility. This interest makes all the difference. Bring it to bear—in conversations, in decisions, in everyday life.
