30 Dolphins Saved

For once no news of destruction and massacre from mankind : in this video humans save dolphins, and it’s great!
On the beach in Arraial do Cabo, Brazil, March 5, 2012, we see appear a band of thirty lost dolphins  coming aground on the beach.
Lifeguards will immediately help, quickly followed by the other people on the beach, and together they push the dolphins back to sea.

Often groups of dolphins die by beaching, it is not clear why:  disruption of their internal sonar, disruption due to military sonars, or outright collective suicide ?
Anyway, congratulations to these Brazilian swimmers for having the right reflex, and for this beautiful rescue 🙂
