Polar bears are endanger mainly due to climate change, which is the result of greenhouse gases. Greenhouse gases (GHGs) in the atmosphere act like a blanket that keeps the earth warm. Over the past 200 years, humans have greatly increased the level of GHGs in the atmosphere by burning fossil fuels like oil and coal. This is like throwing on a second blanket, causing temperatures to rise and melting sea ice. As their habitat shrinks, polar bears are forced to walk and swim longer distances to find food, resulting in weight loss, stress and even death. The cubs can be crushed by collapsing snow caves. We need to help them – and fast. Turning off lights and not driving as often reduces greenhouse gases, so helps reduce climate change. By taking this pledge you can help polar bears survive.
