english: But a supertanker can also be heard coming across a whole ocean, and because the noise that propellers make underwater is sometimes at the same frequency that whales use, then it can damage their acoustic habitat, and they need this for breeding, for finding feeding grounds, for finding mates.
non_english: Ali i supertanker se takođe čuje kako dolazi preko celog okeana, i zbog podvodnog zvuka propelera nekad je na istoj frekvenciji kao kitovi, što može da ošteti njihovo zvučno stanište koje je njima potrebno radi parenja, nalaženja hrane i partnera.
