Humpback whales
|
Humpback whales are sometimes called performers of the ocean. This is because they can make impressive movements when they dive. The name “humpback”, which is the common name for this whale, refers to the typical curve shape the whale’s back forms as it dives. Sometimes the humpback will dive with a fantastic movement, known as a breach. During breaching the whale uses its powerful tail flukes to lift nearly two-thirds of its body out of the water in a giant leap. A breach might also include a sideways twist with fins stretched out like wings, as the whale reaches the height of the breach. A humpback whale breathes air at the surface of the water through two blowholes which are located near the top of the head. It blows a double stream of water that can rise up to 4 meters above the water. The humpback has a small dorsal fin located towards the tail flukes about two-thirds of the way down its back. Other distinguishing features include large pectoral fins, which may be up to a third of the body length, and unique black, and white spots on the underside of the tail flukes. These markings are like fingerprints: no two are the same. Humpback whales live in large groups. They communicate with each other through complex “songs”. |

1.______
With the arrival of the age of “information economy”, intellectual work is becoming a more important source of wealth than manufacturing. Organizations in all walks of life are doing more to spread their information. So people of the Public Relations are hired to speak for them. A lot of our news is actually collected from press releases and reports of events intentionally staged for journalists. In the information age, journalists spend their time, not investigating, but passing on the words of a spokesperson.
2.______
There is a joke in the novel Scoop about the newspaper’s owner, Lord Copper. The editors can never disagree with him. When he’s right about something they answer “definitely”, and when he’s wrong they say “to some extent, Lord Copper.” It seems reasonable to suppose that, in the real world, the opinions of such powerful people still influence the journalists and editors who work for them.
3.______
In countries where the news is not officially controlled, it is likely to be provided by commercial organizations who depend on advertising. The news has to attract viewers and maintain its audience ratings. I suspect that some stories get air-time just because there happen to be exciting pictures to show. In Britain, we have the tabloid newspapers which millions of people read simply for entertainment. There is progressively less room for historical background, or statistics, which are harder to present as a sensational story.
4.______
There is an argument that with spreading access to the internet and cheap technology for recording sound and images we will all be able to find exactly the information we want. People around the world will be able to publish their own eye-witness accounts and compete with the widely-accepted news-gatherers on equal terms. But what it will mean also is that we’ll be subjected to a still greater amount of nonsense and lies. Any web log may contain the latest information of the year, or equally, a made-up story that you will never be able to check.
5.______
Maybe the time has come to do something about it, and I don’t just mean changing your choice of TV channel or newspaper. In a world where everyone wants you to listen to their version, you only have two choices: switch off altogether or start looking for sources you can trust. The investigative journalist of the future is everyone who wants to know the truth.
