Bipolar disorder, sometimes referred to as manic depression, is a mental disorder in which a person's emotions cycle gradually or rapidly between extreme states of being (generally mania or euphoria and depression). Different types of bipolar disorder are recognized based on the illness's presentation. These include Bipolar I, Bipolar II, and Mixed Bipolar. Each year, Bipolar disorder affects 2-3% of the U.S. population. There is no cure for Bipolar disorder, but it can generally be managed with psychotherapy and medication.
The polar bear, scientific name ursus maritimus, is a hypercarnivorous species of bear native to the Arctic. The largest extant species of bear, they are classified as marine mammals and spend most of their time on the sea ice. The polar bear is considered to be extremely dangerous to humans, especially when food is scarce. However, it holds great cultural significance for the Indigenous peoples of the Arctic, such as the Sami and the Inuit. Due to habitat loss, the polar bear is classified as "Vulnerable" by the IUCN.
