Today is International Polar Bear Day, a time to recognize not only the beauty, but also the plight of these gorgeous Arctic predators. Did you know that polar bears are technically classified as marine mammals? This is due to their complete dependence on stable Arctic sea ice. Because polar bears spend 50% of their lives hunting almost exclusively for seals that are found underwater, they can often be found on the edges of pack ice, where it is continually freezing and melting.
The survival of polar bears is contingent on the preservation of sea ice in the Arctic. During times when sea ice melts, polar bears have always come ashore and relied on their fat reserves to hold them over until the ice refreezes and they’re able to hunt again. However, due to climate change, the time that ice remains melted is increasing, meaning the bears must wait longer and longer to hunt again. This often results in malnutrition and, especially for females with cubs, can lead to starvation.
Not only are polar bears crucial for the health of their ecosystems by maintaining balanced populations of their prey, but they are also important to the cultures of many Arctic peoples. Thankfully, it’s not too late to save them! Reduction of greenhouse gases is by far the most important change that needs to be made to save these magnificent creatures. Globally, animal agriculture, especially beef production, is responsible for a larger portion of greenhouse gas emissions than transportation, so cutting back on our meat intake is even more important than limiting time spent driving our cars in the fight to save the polar bear. Electricity and heat generation are also enormous contributors to climate change. Turning our thermostats down in winter, unplugging unused electronics and properly insulating our homes can make a huge impact in terms of maintaining Arctic sea ice and helping keep polar bears alive.
What changes are you going to make to save these incredible animals?
