Listen to the sounds of the ocean as the whales and dolphins hear it. Yeah, it's not so soothing.

Every time a modern container ship churns through the ocean, it puts 190 decibels of sound energy in the water. That's about as loud as standing in the middle of an exploding bomb—and it's a major problem for marine animals, which rely on sound, not sight, to survive.

For whales or dolphins or other marine animals, sound is critical to survival, but human noise—from ships, and from other industry like oil drilling—is making it almost impossible to hear.

Every 10 years, noise pollution doubles.

Read here to learn more about the problem of ocean noise pollution—and possible solutions.
