Sea Otters: How the Furriest of Mammals Can Help Combat Climate Change
When it comes to fighting climate change, there are few species that are as capable as sea otters. These small, furry mammals aren’t the first thought that comes to mind when thinking of species that can help mitigate climate change, but they are in fact quite capable of doing so. This article will explain in detail how sea otters can help mitigate the disastrous effects of climate change.
What Are Sea Otters?
Sea otters (Enhydra lutris) are marine mammals native to the coasts of the Pacific Ocean. They are large members of the mustelid family, which includes weasels, badgers and river otters. These large, furry creatures are one of the few marine mammals that have fully adapted and specialized for aquatic life – their streamlined body shape allows for efficient and graceful swimming, and their thick fur helps them keep warm even in cold waters.
The Conservation Status of Sea Otters
Sea otters have a long history of persecution, and as a result, their numbers have dwindled over the years. Many coastal communities have, unfortunately, over hunted sea otters for their fur, placing them on the brink of extinction in some parts of their range.
Throughout the 20th century, laws were passed to put an end to their hunting, and the U.S., Canada, and Russia have all taken measures to protect them. Thanks to those efforts, the IUCN now classifies the sea otters’ conservation status as “least concern”.
The Role Sea Otters Play in the Ecosystem
The most interesting thing about sea otters is the role they play in their environment. They are considered a keystone species, meaning their presence and activities have a disproportionate effect on their ecosystems.
One of the ways sea otters play a key role in their environment is by influencing the dynamics of their prey, kelp. Kelp harbors vast amounts of sea life, and sea otters play a crucial role in controlling its density by preying upon sea urchins and other grazers. Without sea otters, the populations of these prey species can explode, overgrazing kelp and disrupting entire ecosystems.
How Sea Otters Help Fight Climate Change
The role sea otters play in controlling kelp populations has a direct effect on the mitigation of climate change. As the planet’s temperatures rise, increased temperatures in the ocean are causing a large-scale disruption of aquatic species.
Kelp is able to grow in areas of the ocean with higher temperatures, which helps provide habitats for other species, who may otherwise be unable to survive in more inhospitable conditions. Without sea otters to control the populations of grazers such as sea urchins, the kelp would be consumed and unable to provide these habitats.
In addition, kelp is also very effective at carbon sequestration – the process of removing carbon dioxide from the atmosphere and storing it as organic carbon. Where kelp is abundant, there are greater amounts of carbon stored in its tissues, and the entire kelp bed acts as an enormous carbon sink. Therefore, the more kelp there is, the more carbon dioxide is removed from the atmosphere and the greater the climate change mitigation efforts of sea otters are.
The Benefits of Re-Introducing Sea Otters to New Habitats
Because of their role in mitigating climate change, re-introducing sea otters to areas of their former range is being considered. While re-introduction has its own complexities, it could be an extremely effective way of implementing mitigation strategies. In addition to stabilizing ecosystems, such re-introduction schemes could also promote biodiversity, increase tourism and even create new job opportunities.
Sea Otters are more than a cute, furry face. They are one of nature’s most powerful climate change mitigation agents, helping to preserve the habitats of many species, remove carbon dioxide from the atmosphere and provide numerous benefits to human populations. With continued conservation efforts, Sea Otters can help combat climate change and improve the health of aquatic ecosystems all around the world.
