Scientists and conservation groups are calling for one of the world\u2019s busiest shipping lanes to be rerouted in an effort to protect the world\u2019s largest animal.<\/p>\n

Since 2008, researchers have been painstakingly piecing together clues about a little-known, endangered population of blue whales that live off the southern tip of Sri Lanka. What they have discovered so far hints at one group of cetaceans or even a sub-species. Rather than migrating vast distances like most blue whales, the Sri Lankan population is thought to live in the region year-round, grazing on tiny shrimps and communicating via distinctive vocalisations.<\/p>\n

What has also become clear is the immense threat they face. The whales\u2019 habitat overlaps with a major shipping artery that connects east Asia to the Suez Canal, leaving them vulnerable to ship strikes and noise pollution.<\/p>\n

<\/p>\n

On an average day the whales face off against a relentless barrage of about 200 ships, many of them container ships or oil tankers that stretch up to 300 metres in length.
\n\u201cThe problem for these whales is that they live in a giant obstacle course that we have created,\u201d said Asha de Vos, a marine biologist who launched the first long-term study of the region\u2019s whales in 2008.<\/p>\n

It is a clash playing out in increasing intensity around the world. Between 1992 and 2013, the shipping traffic swelled 300%, as maritime transport became a fixture in roughly 90% of world trade.
\nIn Sri Lanka, the push is now on to tackle what De Vos describes as a \u201cuniquely resolvable issue\u201d, after research suggested that a small shift in the shipping lane could make a big difference to the whales.<\/p>\n

Her longstanding push to move the shipping lane has been backed by a trio of international conservation groups, which have formally called on the Sri Lankan government to propose the route change to the International Maritime Organization.
\n\u201cStudies indicate that if a shipping lane were to be established 15 nautical miles to the south of the current lane, the risk of collisions with blue whales would be reduced by 95%,\u201d read the letter from the International Fund for Animal Welfare (IFAW), Great Whale Conservancy and OceanCare.<\/p>\n

For ships travelling across the world, the 15-nautical mile shift was \u201cinsignificant\u201d, said Sharon Livermore of IFAW. \u201cThis tiny little shift in the location of the shipping lane would make a huge difference to the conservation status of these whales.\u201d<\/p>\n

While there are no firm numbers on how many whales live in the area or how many have been killed by ships, in recent years several carcasses have turned up bearing signs of collision.<\/p>\n

\u201cThe risk is so high that we know that there must be many more being killed than are being reported,\u201d said Livermore. \u201cThe blue whale might be the largest animal on the planet \u2013 these ones are about 22 metres long \u2013 but they pale in significance against a 300-metre cargo ship.\u201d<\/p>\n

The rerouting would also benefit the country\u2019s thriving whale-watching industry and small-scale fishing communities, whose boats have been spotted bobbing perilously close to mammoth vessels in the shipping lane.<\/p>\n

\u201cThere isn\u2019t opportunity for manoeuvre \u2013 the ships can\u2019t suddenly change their course if they see a whale or a fishing boat in their path, so the only way to reduce the risk is to move those ships away from this critical area,\u201d said Livermore.<\/p>\n

Her organisation first approached the Sri Lankan government about moving the shipping lane in 2015, calling it a unique opportunity to protect blue whales, 90% of which were slaughtered by whalers in the 20th century.<\/p>\n

Others have also made overtures. In 2017, the World Shipping Council, which represents most of the world\u2019s shipping companies, urged the Sri Lankan government to consider the move, as did the International Whaling Commission in early 2021.
\nThe previous Sri Lankan government refused to sign off on the proposals, citing concerns in 2019 about the economic impact of the move. The country\u2019s Marine Environment Protection Authority did not respond to a request for comment.<\/p>\n

The vast majority of the ships using the lane do not stop in Sri Lanka but only transit through the area, said De Vos, suggesting the economic cost of the move would be minimal. \u201cNone of us want the industry to stop using our waters or for the industry to collapse,\u201d she added.<\/p>\n

The idea of moving shipping lanes is not without precedent. In 2007 officials in the US worked to shift a lane off the coast of Massachusetts, teasing apart the steady stream of container ships and tankers from the area\u2019s fragile baleen and North Atlantic right whales. The move has been credited with reducing the risk of ships striking the whales by 81%.<\/p>\n

The same approach was later applied to the coast of California, where the overlap between a busy ocean highway and key feeding grounds for whales was blamed for the deaths of at least 100 whales between 1988 and 2012. In an area dotted with oil rigs and hemmed in by the Channel islands, the shipping lane could only be moved one nautical mile north. Even so, the small change, announced in 2012, helped to reduce the number of collisions between ships and whales.<\/p>\n

These gains were heightened in 2020 with the launch of Whale Safe, a tool that compiles data from sources such as an underwater hydrophone, satellites tracking ocean conditions and local whale sightings to offer a near-real time estimate of where the area\u2019s whales are at any given moment in the Santa Barbara channel.<\/p>\n

In some cases companies have taken matters into their own hands. Amid concerns by researchers and conservationists over the eastern Mediterranean\u2019s dwindling colony of endangered sperm whales, in late January the MSC Group said it would become the first major shipping company to reroute ships travelling along the west coast of Greece.<\/p>\n

In Sri Lanka, the risks of having a shipping land that hugs the country\u2019s coast were laid bare in May, after a cargo ship laden with toxic chemicals caught fire, dumping a hazardous mix of chemicals into the waters off Colombo.<\/p>\n

The heavy cost to Sri Lanka from shipping was made clear in May, after a cargo ship laden with toxic chemicals caught fire, dumping a hazardous mix of pollutants into the waters off Colombo. The spill poisoned the waters, left nearby beaches coated in plastic pellets and covered stretches of water in an oil slick, in what was described as the country\u2019s worst-ever maritime disaster.<\/p>\n

The tragedy struck a nerve with many people in Sri Lanka, said De Vos. Now she hoped the sentiment would extend to protecting the \u201cunorthodox whales\u201d that share the country\u2019s waters.
\n\u201cThey\u2019re so different to blue whales anywhere else in the world. It\u2019s not just that it could be a separate subspecies, it has a different dialect, different feeding habits, different behaviours,\u201d she said. \u201cWe could start losing a culture of whales.\u201d<\/p>\n
