[00:09.46]The Wonders of Dolphins
[00:13.90]1.Here's a true story.In June 1990, Keith,Steve and Dave, three friends,
[00:25.16]were fishing about 35 miles off the east coast of America when their boat sank
[00:34.22]They clung¹ to the boat praying for rescue.
[00:39.26]The hours went by.Night came.
[00:44.72]2.'We had been thinking about sharks all night,'said Keith.
[00:50.99]'The next morning a really big fish approached.
[00:56.14]I asked Steve,"Do you know what that fish is?"He said it was a shark.
[01:03.90]But just then,suddenly there were dolphins all around us
[01:10.66]They pushed the shark,and drove it away.
[01:15.83]Steve said,"Tell them to go and get help,"so I said,"Hey, Flipper²,go get help
[01:25.19]and the dolphins all disappeared.
[01:28.95]Thirty minutes later they came back,bringing a coastguard boat with them.'
[01:35.71]3.The men were rescued
[01:38.87]The coastguards told them
[01:42.43]that the dolphins swam in front of the boat all the way until they located them
[01:49.58]Keith believes absolutely that God sent the dolphins to save him and his friends
[01:57.52]Others would say that the dolphins acted on their own,without divine³ orders
[02:04.79]Why they acted like this is a mystery to most people.
[02:10.43]4.The Ancient Greeks certainly believed that dolphins were very special
[02:17.09]They believed dolphins could think and act like humans,
[02:23.26]and had many stories of dolphins befriending young boys
[02:29.03]and saving sailors by towing⁴ them to the shore.
[02:34.88]In their days,the penalty⁵ for killing⁶ a dolphin was death.
[02:41.12]5.In modern times,we know a number of scientific facts about dolphins
[02:48.39]We know that they are mammals, not fish.
[02:52.83]They must come up to the surface to breathe air
[02:57.50]They can live to about 35 or 45.
[03:02.96]They are among the most intelligent animals in the world,
[03:08.53]with good memories,and can be trained to follow complicated sets of commands
[03:15.79]They use a system like sonar to locate objects,
[03:21.95]and they communicate with each other.
[03:26.03]6.One other feature of their behaviour is famous.
[03:30.78]They are the only wild animal that seeks out and befriends people,voluntarily
[03:38.33]In the past 50 years,there are perhaps a dozen or more examples
[03:45.59]of individual dolphins around the coasts of Europe,
[03:50.84]America and New Zealand which have regularly approached people
[03:57.82]and played games with them, and offered them 'unconditional⁷ love'.
[04:03.98]7.We have not repaid⁸ them well.
[04:08.24]Fishermen kill many thousands of dolphins each year.
[04:13.39]These days fishermen use nets described as'walls of death'.
[04:20.47]They vacuum all the fish from the sea.Only emptiness remains⁹.
[04:27.83]Although dolphins are not the intended prey,
[04:33.29]there is no chance that they can escape.
[04:37.55]8.One famous television series from 1962
[04:43.72]is also unintentional ly to blame for the suffering of many dolphins.
[04:50.35]In my boyhood,
[04:53.38]I remember watching the funny adventures of 'Flipper the dolphin
[04:58.81]and his friend Sandy.
[05:02.05]The cute dolphin show was so popular that people wanted to see real dolphins
[05:01.05]and as a result dolphinaria were built throughout America,
[05:00.05]and many more dolphins were captured and imprisoned¹⁰ inside them.
[04:59.05]9.In a few areas of the world,more enlightened¹¹ people have discovered
[04:58.05]that dolphins have hidden powers to heal people with mental problems.
[04:57.05]Dr Horace Dobbs has introduced people with severe depression
[04:56.05]to wild dolphins in the sea.The people go without fear.
[04:55.05]The possibility that the dolphins might hurt them does not enter their minds
[04:54.05]The dolphins seem to understand,
[04:53.05]and look sympathetically into the eyes of the human patients,
[04:52.05]whose conditions almost always improve.
[04:51.05]People who have observed these experiments are very impressed with the results
[04:50.05]10.Some enthusiasts¹² believe that dolphins have almost supernatural powers
[04:49.05]These people suggest that dolphins emit a wave of energy
[04:48.05]that goes around the Earth.
[04:47.05]They see the dolphins as magical creatures.
[04:46.05]This is perhaps too extreme for most people,
[04:45.05]but there is no doubt that they are wonderful animals,
[04:44.05]and we still have much to learn from them.
