Whaling Vs. Pollution: What's The Deadlier Threat?

Whaling and pollution are two major threats to whales, with both causing significant harm to their populations. Whaling, the practice of hunting whales, has a long history and has been recognised as a problematic and unsustainable industry due to its decimation of whale populations, inhumane methods, and targeting of top marine predators. Pollution, on the other hand, poses a threat to whales through various forms such as oil spills, chemical toxins, plastic waste, and noise pollution. While the number of whales killed by whaling is significant, with an estimated minimum of 300,000 whales and dolphins killed annually, the impact of pollution is also severe, affecting the health and behaviour of whales and even leading to their deaths.

Whaling is an inherently cruel practice, with harpoons and other devices causing prolonged suffering

Whaling is a destructive and unethical practice that poses a significant threat to whale populations and marine ecosystems. While understanding the historical context of whaling is essential, it does not justify its continuation in the present day. The cruelty inflicted on these sentient beings, coupled with the detrimental impact on the delicate ocean ecosystem, provides a strong argument for the cessation of whaling.

Whaling is inherently cruel, and the use of harpoons and other devices causes prolonged suffering and painful deaths. The methods employed to kill whales often involve harpoons, explosive devices, and other brutal tools, resulting in extended periods of agony. Whales can suffer for up to 25 minutes or more before succumbing to their injuries. Smaller cetaceans may endure even worse treatment, with hooks inserted into their blowholes and spinal cords severed while they are still conscious. The reality is that whales are sentient beings capable of feeling pain, fear, and distress, making this treatment unacceptable and inhumane.

The act of killing whales, particularly with explosive harpoons, has been widely criticised as unacceptably cruel. Despite claims that explosive harpoons ensure a quick death, numerous expert findings contradict these assertions. The challenges of accurately striking a large, moving whale from a moving vessel in unpredictable sea conditions make it extremely difficult to guarantee a swift and humane death. The margin for human error further complicates the situation, as evidenced by reports from Norway and Japan, where a significant proportion of whales did not die instantaneously during their hunts.

The force required to kill a whale is immense, and the amount of violence needed to slaughter these massive animals in the open ocean is unacceptable. The suffering inflicted on whales is not limited to physical pain but also includes the terror and distress they experience during the process. The reality is that there is no humane way to kill a whale at sea, and the cruelty of the act must be recognised and addressed.

The impact of whaling extends beyond the suffering of individual whales. The loss of whale populations disrupts the ocean's delicate balance and affects the entire marine food chain. Whales, as top predators in the marine ecosystem, play a crucial role in maintaining the health and stability of their environment. The decimation of whale populations through whaling has far-reaching consequences that are only beginning to be understood.

Whaling has decimated whale populations, with some species now near extinction

Whaling has had a devastating impact on whale populations, with some species pushed to the brink of extinction. Commercial whaling, which was banned in 1986, led to a massive decline in global whale numbers. Despite the ban, countries like Japan, Norway, and Iceland have continued whaling activities, killing nearly 40,000 large whales. The practice of whaling dates back centuries, but it was during the 20th century that industrial whaling decimated most whale species. The Blue Whale, for instance, saw its population decline by 98.5%, from 340,000 to just 5,000 individuals.

Fin whales were also heavily impacted by whaling, with close to a million slaughtered worldwide in the 19th century. In the 20th century, 99% of the Eastern North Pacific fin whale breeding population was wiped out. This species is now showing signs of recovery due to international conservation efforts and the enforcement of the whaling ban. The future of fin whales in the Gulf of California is dependent on the recovery of the Eastern North Pacific population, as gene flow between these groups is essential for their survival.

The North Atlantic right whale, the Arctic bowhead, and the Pacific blue whale are among the species still in critical condition. While some populations are stable or showing signs of recovery, whaling has undeniably decimated whale numbers, and the road to recovery is long for many species.

Whales are long-lived and have low reproductive rates, with only one calf born every 1-3 years. This makes them particularly vulnerable to the impacts of whaling. The International Whaling Commission (IWC) has played a crucial role in regulating whaling and enforcing the commercial whaling moratorium. Despite this, some countries continue to exploit loopholes and engage in whaling for profit, threatening the survival of already vulnerable whale populations.

While pollution also poses a significant threat to whales, with noise, oil spills, and chemical pollution all having detrimental effects, it is clear that whaling has been the more immediate driver of whale populations toward extinction. The combination of whaling and pollution further exacerbates the challenges faced by these majestic creatures, highlighting the urgent need for stricter conservation measures and global cooperation to protect whales from human-induced threats.

Pollution, such as oil spills, marine debris, and industrial pollutants, poses a serious threat to whales

Pollution is a significant threat to whales, and it comes in various forms, including oil spills, marine debris, and industrial pollutants. Each of these pollutants has detrimental effects on the health and survival of whales, contributing to a decline in their populations.

Oil spills, such as the Exxon Valdez disaster in 1989, which released 11 million gallons of oil into Alaska's Prince William Sound, pose a severe danger to whales. While whales do not directly ingest oil, they can be impacted by consuming contaminated prey or inhaling toxic fumes. The oil can also enter their blowholes, leading to pneumonia and other complications. Additionally, oil spills can kill off smaller creatures, such as krill, which are a vital food source for whales.

Marine debris, including derelict fishing gear and plastic waste, often entangles whales and traps them. Even the largest whale species can fall victim to this, leading to their immobilization and eventual death. Furthermore, plastic pollution in the ocean is ingested by whales, mistaking it for potential food. This ingestion of plastic debris can lead to health complications and an increased risk of death, as seen in the case of sperm whales that washed ashore in Europe with large amounts of plastic in their stomachs.

Industrial pollutants, such as PCBs and noise pollution, also threaten whale populations. Noise from industrialization can interfere with the communication and behaviour of whales, driving them away from areas essential for their survival. The accumulation of pollutants in their food supply can further impact their health, as certain toxins can adversely affect their nervous system.

The impact of pollution on whales is evident, and ongoing studies, such as those examining the effects of the 2011 oil spill in the Gulf of Mexico, aim to improve our understanding of the consequences for whale populations. By recognizing the threats posed by pollution, we can work towards mitigating these risks and protecting whales from the detrimental effects of human activities.

Noise pollution from human activities can injure and kill whales and dolphins

While it is difficult to determine whether pollution or whaling kills more whales and dolphins, noise pollution from human activities certainly poses a significant threat to these creatures.

Whales and dolphins rely on their sense of hearing for survival, with their world being one of water and sound. They use echolocation and vocal communication to navigate, find food, and connect with each other. However, noise pollution from human activities, such as commercial shipping, oil exploration, seismic surveys, and military sonar exercises, disrupts their natural behaviours and interferes with their ability to communicate. This can lead to whales and dolphins becoming disoriented, unable to hunt successfully, and driving them away from areas crucial for their survival.

The excessive noise from anthropogenic sources can reach volumes of up to 200 decibels and persist for over an hour, in stark contrast to the temporary and directed nature of whale calls, even when they reach volumes of over 180 decibels. Military sonar and seismic air guns, with their high intensity and excessive volume, can cause panic in whales and dolphins, leading them to ascend too rapidly and suffer from decompression sickness, haemorrhaging to the heart and brain, and even death.

The impact of noise pollution extends beyond the direct effects on whales and dolphins. As ecosystems in the ocean are interconnected, the disruption caused by noise pollution can have indirect consequences on other species. For example, if a whale strands on a beach due to noise pollution, its body may not sink to the seafloor as it normally would at sea, affecting the local ecosystem.

While there are currently no international legal regulations specifically addressing ocean noise pollution, efforts are being made to advocate for its regulation and reduce its impact. The European Commission, influenced by organisations like IFAW, has set a mandatory cap on underwater noise from human activities at sea, with each member state deciding on implementation methods. Additionally, campaigns such as Blue Speeds aim to reduce ship speeds in Europe, and over 100,000 people have signed the petition.

Whale watching is a significant industry in many parts of the world, providing an alternative source of revenue to whaling

Whale watching has become a significant industry in many parts of the world, providing an alternative and sustainable source of revenue to whaling. Whaling has long been recognised as a problematic practice due to the decimation of whale populations, the inhumane methods used to kill these intelligent creatures, and the negative impact on the marine ecosystem.

The growth of the whale-watching industry demonstrates a shift in the value of whales, from their commercial worth as a resource to their worth as a tourist attraction. Whale watching provides an alternative source of income for communities that once relied on whaling. In 2009, a study estimated that 13 million people went whale watching worldwide, generating direct revenue of US$872.7 million and indirect revenue of $2,113.1 million in tourism-related businesses. This indicates the significant economic potential of whale watching as a sustainable alternative to whaling.

For example, in Alaska, whale watching has become an important economic driver. In 2019, approximately one-quarter of Alaska's 2.2 million summer visitors, about 553,000 people, spent an estimated $86 million on whale-watching tours. The industry directly employed 460 workers in Juneau, earning $13.1 million in labour income. In Seward, the state's second-largest whale-watching destination, an estimated 93,400 visitors participated in paid whale-watching tours, generating $5.9 million in labour income.

Whale watching also has positive conservation and educational outcomes. In South Africa, for instance, the whale-watching industry in Plettenberg Bay is linked to conservation and education efforts through local volunteer marine conservation organisations. Additionally, whale watching can foster a sense of community identity and connection to historical traditions, similar to the cultural significance of whaling for some communities.

The growth of the whale-watching industry highlights a global recognition of the importance of healthy whale populations to local economies and ecosystems. By valuing whales as living attractions, whale watching provides a sustainable alternative to whaling, contributing to economic growth and the preservation of these extraordinary creatures.
