Hundreds of dolphins saved after beaching on Filipino coast
The dolphins were saved thanks to quick action by local residents and fishermen. Five out of the 300 died. The beaching was caused by a heat wave, or an anomalous wave.

Manila (AsiaNews/Agencies) - Filipino environmentalists continue to monitor the coast of the province of Bataan, west of the bay of Manila, to prevent more beachings of dolphins. About 300 of the mammals got stuck yesterday.

Dozens of volunteers and fishermen from the villages of Pilar and Orion immediately plunged into the sea, to help the dolphins stranded on the coast. An underwater tremor or a sudden heat wave are the hypotheses favored by the experts to explain how the dolphins lost their sense of direction.

It is not rare to see dolphins run aground in the Philippines, but the phenomenon had never before been seen on such a large scale. Quick action by the inhabitants of the area prevented genuine carnage. They plunged into the ocean en masse, trying to frighten the dolphins to make them swim away. A group of boats then guided them out to sea, into deeper water.

Out of the 300 that were beached - of the genus Peponocephala, found throughout tropical waters around the world - only five of them died, one of them a pregnant female. Malcom Sarmiento, director of the Bureau of Fisheries and Aquatic Resources, calls the phenomenon "unusual" because of its large scale, and explains that it could have been caused by "a heat wave or disturbance at sea." This could have caused the entire school to lose its sense of direction, or just the leader, which the other dolphins would have followed to the shore.

Pope in Turin tells young people to be chaste in love, go against the flow and not retire at 20In his last meeting on the first day of his visit to Turin, Francis met young people in Vittorio Square. In a Question and Answer exchange, he talked about love, friendship and loss of trust towards life. "I understand you. How many hypocrites speak of peace and sell weapons. How can one trust? By following Christ, whose act of extreme love, i.e. the Cross, saved humanity." The pontiff also looked at the horrors of the 20th century as evidence of the loss of trust towards world powers. He urged young people “not to retire at 20,” but “live, don’t just exist.”
