Polar Bears

Physical Description

Polar bears (Ursus maritimus) are the largest land carnivores. Adult males can weigh over 1,000 pounds and measure up to 3 meters in length. They have black skin under a thick layer of white fur that provides camouflage and insulation in Arctic environments.

Location

Polar bears are found throughout the Arctic region, including Canada, Alaska, Greenland, Norway, and Russia. Canada is home to approximately 60% of the global population.

Ecology

Polar bears are apex predators and primarily feed on seals. They rely on sea ice as a platform for hunting, resting, and breeding. Their presence influences the population and behavior of prey species and contributes to Arctic ecosystem balance.

Societal Role

Polar bears are cultural icons and hold spiritual significance for many Indigenous communities in Canada. They also symbolize the global impact of climate change.

Conservation Status

Listed as “Vulnerable” by the IUCN. In Canada, they are designated as a species of Special Concern under the Species at Risk Act.

Population Estimate

Estimated 22,000–31,000 globally. Canadian subpopulations include approximately 16,000 individuals.

Last Reviewed

The Committee on the Status of Endangered Wildlife in Canada (COSEWIC) reviewed their status in 2023.

Historic Causes

Historically, overhunting impacted some polar bear populations. However, hunting is now regulated and less of a concern in most regions.

Current Threats

Impacts

As sea ice disappears, polar bears are forced to swim longer distances or move inland, leading to malnutrition, decreased reproduction, and increased mortality.

Research

Monitoring includes aerial surveys, satellite tagging, and climate modeling to predict habitat loss.

Actions

Led By

Effectiveness

International cooperation through agreements like the 1973 Polar Bear Agreement has helped regulate hunting, but more is needed to address climate-driven threats.

Global Examples

Norway's Svalbard regulations strictly limit human activities in polar bear habitat and have shown success in preserving their environment.

Vision

Stable or growing polar bear populations, secure habitats with preserved sea ice, and minimal human-wildlife conflict.

Immediate Actions

Sustainable Practices

Education

Public campaigns about climate change, responsible tourism, and Indigenous-led conservation help shift attitudes and encourage meaningful action.

Historic Causes

Historically, overhunting impacted some polar bear populations. However, hunting is now regulated and less of a concern in most regions.

Current Threats

Loss of sea ice due to climate change

Reduced access to prey (seals)

Pollution (e.g., persistent organic pollutants)

Human-wildlife conflict as bears search for food on land

Impacts

As sea ice disappears, polar bears are forced to swim longer distances or move inland, leading to malnutrition, decreased reproduction, and increased mortality.

Research

Monitoring includes aerial surveys, satellite tagging, and climate modeling to predict habitat loss.

Actions

National Polar Bear Conservation Strategy (Canada)

Arctic marine protected areas

Regulated subsistence hunting in partnership with Indigenous communities

Led By

Environment and Climate Change Canada

World Wildlife Fund (WWF)

Indigenous Wildlife Boards (e.g., Inuvialuit Game Council)

Global Examples

Vision

Stable or growing polar bear populations, secure habitats with preserved sea ice, and minimal human-wildlife conflict.

Immediate Actions

Reduce carbon footprint (drive less, fly less, switch to renewables)

Support Arctic research initiatives

Promote wildlife-safe waste management in northern communities

Sustainable Practices

Emissions reduction policies

Eco-tourism practices that respect bear habitats

Safer shipping lanes away from polar bear zones

Education

Public campaigns about climate change, responsible tourism, and Indigenous-led conservation help shift attitudes and encourage meaningful action.
