3.000 Dolphins Dead on the Coast of Peru

On an unprecedented catastrophe more than 3.000 dolphins were found dead on the desert beaches of Peru. 

The news strangely didn't receive the disclosure that would be expected. Few media reports carried out on site in order to seek an explanation for the largest mass killing of these friendly mammals.

Peruvian biologist Carlos Yaipen of the Scientific Organization for Conservation of Aquatic Animals said activity from petroleum companies in the waters is to blame in this instance. A controversial technique for detecting oil beneath the seabed, using sonar or acoustic sensing, is leading the massive die off of marine life. 

 

"The oil companies use different frequencies of acoustic waves and the effects produced by these bubbles are not plainly visible, but they generate effects later in the animals. That can cause death by acoustic impact, not only in dolphins, but also in marine seals and whales."     more here
