This part of the Indian Ocean is a vital link between Asia to the Suez Canal, making it a busy, noisy, and dangerous area for the pod to live in permanently. The main port area has been coined an βobstacle courseβ by marine biologists.
Blue whales can be up to 30 metres long and 150,000kg in weight. Theyβre the largest of all mammals, with a heart the size of a Volkswagen Beetle. Theyβre also at the top of the food chain, meaning they are important to maintain the balance of the ocean.
Considering this, it might be hard to believe theyβd remain unspotted in the ocean, but theyβre no comparison to cargo ships which can be up to 300 metres long. In the last decade, many whale carcasses have washed ashore with injuries caused by boat collisions.
In a port near California, shipping routes were altered after tankers and containerships frequently encountered whales migrating through the area. Following the change, California reported an 81 percent reduction in whale encounters.
Similar changes were made off the coast of Massachusetts, proving that simple, carefully planned changes to our everyday routines can help us live in better harmony with the natural world at no real cost to us.

Unfortunately, six decades of intense whaling activity wiped out almost 200,000 blue whales, bringing them close to extinction. Today, only 10,000 β 25,000 of them are estimated to be left in the wild.
Since the global ban on commercial whaling in 1986 whale populations have slowly grown, but taking steps to protect them β especially when theyβre as obvious as redirecting ships β is something weβll need to continue looking out for.
The case for protecting the pod off Sri Lanka is strengthened by the whalesβ uniqueness. With their own dialect, prey of choice, and unique behaviours, the group has created its own culture which could be lost if changes are neglected.
Weβll be keeping our fingers crossed that the requests of marine scientists and international conservation groups are heard by the Sri Lankan government to pass the bill for new shipping routes.
