Humans have altered the Earth so much that migratory animals are facing extinction

Threats to Migratory Species

Many animals are being hunted to extinction or being affected by climate change. Female leatherback turtles are among the world’s most intrepid creatures, making journeys as far as 10,000 miles after nesting to find food in far-away seas. They’ve been known to set off from tropical Southeast Asia up to the cold waters of Alaska, where jellyfish are common.

Challenges Faced by Migratory Species

Travelling such long distances exposes animals to threats, including fishing nets, poachers, pollution, and waters warmed by the climate crisis, which force species to travel further to find food. These risks are causing many migratory species to face extinction due to human interference.

Declining Populations and Habitat Loss

The UN report states that over 20% of migratory species are threatened, including whales, sharks, and migratory fish, with 97% of migratory fish facing extinction. Overexploitation and habitat loss caused by human activities like farming, infrastructure development, and fragmentation of migratory routes are the main contributors to population declines.

Climate Change and Other Threats

Climate change forces some species to travel farther and at different times of the year, disrupting their ability to find food or mates. Narwhals, bats, and other migratory species are facing challenges due to warming temperatures, habitat destruction, and noise pollution. The UN report emphasizes that human activities are jeopardizing the future of these species and the ecosystems they support.
