Do you know how much important the "hearing" is to whale's communication, navigagation and feeding. Whales are auditory animals and when the ships make loud noise while passing through their habitat, it disrupts whales' daily life.
Everything in their lives depends upon sound communication and a ship interferes with almost 90% of their communication especially with the killer whales'. We can do somethings like putting up speed limits or no-go zone. The shipping companies can put up sound check stations for noise maintenance.
By reducing the noise pollution for the whales to thrive in their natural environment is important for them and also for everyone.
