   Seals face an uncertain future with climate change altering ocean currents and prey availability while worsening storms and rising sea levels are affecting vital resting and breeding sites. Toxic pollutants continue to enter waterways and the ocean.

   Oct 31, 2024 · The degradation of natural habitats poses a significant threat to seal populations, disrupting their breeding, resting, and foraging environments. Coastal development often leads to the destruction of haul-out sites where seals rest and nurse their young.

   • Ocean noise. Often overlooked because it can’t be seen, ocean noise is a significant threat to a number of marine species. Animals like whales and dolphins that hunt and communicate using sound are severely impacted by excessive noise caused by shipping activity, military sonar, and seismic exploration by oil and gas industries.
   • Vessel strikes. Another threat that is linked to shipping is vessel strikes on marine wildlife. These are exactly what they sound like—large vessels, such as shipping containers, collide with aquatic animals, usually whales.
   • Climate change. The increase in global temperatures seen with climate change has—and continues to have—devastating effects on the ocean. Warming temperatures have led to coral bleaching, threatening an estimated 75% of the world’s reefs, while ocean acidification is having dire consequences for many marine species too.
   • Entanglement in fishing gear. Marine animals—from whales, dolphins, and seals to turtles and seabirds—often become caught and trapped in nets and lines used by commercial fisheries.

   The largest threats to seals are humans and the byproducts of our activity. Historically, hunters targeted seals for their fur and hunted several species to extinction. Today, seal hunting is much better regulated to help preserve seal populations.

   Seals, like other marine mammals, rely entirely on seafood, they do not have the luxury of dietary choice as we do. By 2020, the UN aims to end overfishing and conserve at least 10% of all coastal and marine areas.

   Dec 17, 2020 · While the total number of monk seals in the main Hawaiian Islands appears to be slowly increasing, human-related lethal threats are hampering that growth. Human-caused trauma (physical injury, shooting, etc.), gillnet entanglement, and toxoplasmosis cause the most deaths.

   What are the biggest threats to seals?

   • The largest threats to seals are humans and the byproducts of our activity. Historically, hunters targeted seals for their fur and hunted several species to extinction. Today, seal hunting is much better regulated to help preserve seal populations. A byproduct of human activity is greenhouse gases, which contribute to climate change.

   Are seals threatened by discarded debris?

   • Unfortunately, seals in remote areas are still threatened by discarded debris. If you are at the beach or out on the water and see any kind of debris, please consider picking up and disposing it. Any debris pose a serious threat to the health and livelihood of seals.

   Are seals threatened by entanglement?

   • Seals are also threatened by entanglement, primarily in materials sourced from fishing industries. Debris can trap seals. Young seals seem especially vulnerable to entanglement. Early intervention for entrapped individuals has demonstrated a reduction in entanglement related mortality.

   How dangerous are toxins in Antarctic seals?

   • These toxins are so widespread they have been detected at dangerous levels in Antarctic seals. Human over-fishing is seriously depleting fish stocks and food availability for seals while untold numbers of seals face an agonising death, entangled in fishing gear and other marine rubbish.

   How does a seal's death affect the population?

   • Every seal’s life is important, but mathematically, the impact of one seal’s death on the whole population depends a lot on its age and sex. The death of a newborn or a very old seal affects the population far less than the death of a young adult female.
