Into the Unknown
In the days of Stanley and Livingstone, much of the world was still unexplored. Today, most places on the surface of the world have been mapped. Some places, however, are still waiting to be discovered. Some of these are underground, in deep caves called blue holes.
A blue holes is a special kind of inlandunderwater cave. The cave forms when the earth above it falls in. Some of the world’s most spectacular blue holes are located in the Bahamas. The islands there may have more than a thousand blues holes. These caves are very deep – for example, Dean’s Blue Hole, the deepest blue hole in the world, is more than 660 feet (200 meters) deep.
Diving into blue holes is extremely dangerous. Near the top of a blue hole, there is a layer of poisonous gas. This gas causes itching, dizziness, and – in large amounts – death. Divers must also be fast. They have to get in and out of a cave before their oxygen run out. Additionally, it’s very dark in these caves, so it is very easy to get lost. Divers therefore have to follow a guideline as they swim through a blue hole. If they lose the guideline, they may not find their way back out of the cave.
If blue holes are so dangerous, why do explorers and scientists risk their lives to explore them? One reason is that these underwater caves can provide valuable scientific information. They provide clues about geology, archaeology, and even astrobiology – the study of life in the universe. For example, some blue hole creatures, such as the remipede, probably haven’t changed for millions of years. Divers have also found bacteria that can live without oxygen. Similar life forms probably existed on Earth billions of years ago.
In addition, the oxygen-free environment of the blue holes preserves bones of humans and animals that fell into the caves long ago. By studying the blue holes, we can understand what life was like in prehistorictimes. As cave diver Kenny Broad says, “I can think of no other environment on Earth that is so challenging to explore and gives us so much scientifically.”
Windows on an Alien World?
An inland blue hole’s water is very still and has different layers. A layer of fresh rainwater floats on top of salt water. The fresh water keeps oxygen from the atmosphere from reaching the salt water. Brightly colored bacteria live where the two layers meet. Scientists believe these bacteria could teach us about life in outer space. Astrobiologist Kevin Hand says the bacteria may be similar to forms of life that might exist on Jupiter’s fourth largest moon, Europa. “Our study of life’s extremes on Earth,” says Hand, can help increase “our understanding of habitable environments off Earth.”

The Harder Hard Sell
It was Lord Leverhulme, the British soap pioneer, who is said to have complained that he knew half of his advertising budget was wasted, but didn’t know which half. The real effects of advertising have become more measurable, exposing another, potentially more horrible, truth for industry: in more cases, it can be a lot more than half of the budget that is going down the drain.
The advertising industry is passing through one of the most disorienting periods in its history. This is due to a combination of long-term changes, such as the growing diversity of media and the arrival of new technologies, notably the internet. With better-informed consumers, the result is that some of the traditional methods of advertising and marketing simply no longer work.
The media are the message
But spending on advertising is up again and is expected to grow this year by 4.7 per cent to $343 billion. How will the money be spent? There are plenty of alternatives to straightforward advertising. They range from public relations to direct mail and include customer promotions (like paying a retailer for shelf space), telemarketing, exhibitions, sponsoring events, product placements and more. These have become such an inseparable part of the industry that big agencies are now willing to provide most of them.
As ever, the debate in the industry centers on the best way to achieve results. It is more cost-effective, for instance, to use a public relations agency to invite a journalist out to lunch and persuade him to write about a product than to pay for a display ad in that journalist’s newspaper? Should you launch a new car with glossy magazine ads, or – as some car makers now do – simply park demonstration models in shopping malls and motorway service stations? And is it better to buy a series of ads on a specialist cable TV channel or splurge $2.2m on a single 30-second commercial during this year’s Super Bowl?
Net Sales
Such decisions are ever harder to make. For a start, people are spending less time reading newspapers and magazines, but are going to the cinema more, listening to more radios and turning in ever-increasing numbers to a new medium, the Internet (see chart 1). No one knows just how important the Internet will eventually be as an advertising medium. Some advertisers think it will be a highly cost-effective way of reaching certain group of consumers. But not everyone uses Internet and nor is it seen as being as being particularly good at building brands. So far, the Internet accounts for only a tiny slice of the overall advertising pie (see chart 2) although its share has begun to grow rapidly.
Despite all of these new developments, many in the advertising business remain confident. Rupert Howell, chairman of the London arm of McCann Erickson, points out that TV never killed radio, which in turn never killed radio, which in turn never killed newspapers. They did pose huge creative challenges, but that’s OK, he maintains: “The advertising industry is relentlessly inventive; that’s what we do.”
