Widespread logging practices are destroying natural habitats for many species of bears. Their reliance on large territories makes them particularly vulnerable. Mining for oil and minerals, agricultural practices, growing urban encroachment and road building, all contribute to this problem. Pollutants and oil spills also pause a threat. Furthermore, we are already seeing the impact of climate change of Polar bear populations.
One of the biggest threat to bears in the modern world comes from changes in their environment. Widespread logging, for exotic woods and agricultural development, are forcing bears into ever smaller areas, diminishing their food source and increasing the risk of direct conflict with people. Bears are forced out of their natural habitat and destroy crops, attracted by easy access to food around human settlements. Logging and urban developments often isolate bears from one another, which reduces breeding opportunities and leads to a decrease in populations. Large plantations for palm oil, coffee as well as mining for mineral and oil, are replacing previously natural habitats. Animals found in these areas are often killed as a perceived threat to the operation. Furthermore, poachers know that a lack of cover in these man-made landscapes makes bears very vulnerable and can take advantage of this.
Pollutants in the water and in the food chain are having a detrimental effect on bear populations. Studies have shown that Polar bears have dangerous levels of pollutants in their systems, as toxins build up through the food chain. They are also under threat from massive oil spills. As top predators, pollutants accumulate in their diet and affect their hormonal levels, immune system and reproductive abilities. This may also explain the decreasing size of the species over the years.The polar bear is also the first species of mammal given some protection due to concerns about climate change. Diminishing sea ice coverage is forcing bears to look further for suitable food source as access to prey is becoming more difficult.
Responsible consumerism is key. Avoid exotic woods that come from unsustainable sources when purchasing products. Hauser Bears would also like to see more clarity on the use of palm oil in products so consumers can make informed choices.
