I have to ask.... how can sonar (err... sound reflections) kill anything?

“I have to ask.... how can sonar (err... sound reflections) kill anything?”

Not to mention, don’t whales already sort of use their own sonar?

They are not talking about passive SONAR.

Imagine standing next to a bass speaker designed for stadium use. Multiply the sound level by a thousand times.

These sub sonars project enormous power.

I don't know and don't really care what the enviros claim, but I don't doubt there is potential damage to whale hearing (if that is the correct term) or perhaps other internal organs if they are close by.
