This sad video was made as tribute to a species that is close to extinction: the Yangtze River Dolphin, also known as Baiji. This species has even been classified as totally extinct since 2006, but there is still doubt, as several people from different regions have claimed to have seen some individuals, although this has not been confirmed. It is an invitation to become aware of our actions to realize that we are destroying the nature and our planet. How far the selfishness of man will get? How many species will become extinct before we take care of them?
