During her annual migration, a humpback whale, who lost her way, entered San Francisco Bay and began to climb the stream on the Sacramento River. If this 45 tonne whale continued to rise through the current that had lost its life, as the flow of running water decreased, the risk of the whale being sunk increased considerably.
In the world there are only 1200 wavy whales. Therefore, it was mandatory to start your complaint. Environmentalists, scientists and authorities have turned to push the whale towards the sea. However, this did not want to go back. After almost two weeks of struggle they have managed to push the whale towards the sea. He is saved!
