A long time ago, before human beings lived on the earth, little coral polyps(水螅)settled around tropical (热带的)coastlines and constructed corals. Over a long period they created lots of reefs. Yet, pollution, climate change and commercial fisheries are limiting the chance of future generations knowing or seeing many of the reefs and sea creatures that exist. Hence, take action to dive now and you can explore the underwater world.
Commercial underwater diving began in ancient Greece. Diving in general means that the whole body is completely in water. On that account there are lots of exciting and quite adventurous ways to dive, like shark cage diving, scuba diving(戴水肺潜水)and reef diving.
There are great coral reefs all over the world, but usually they are situated in warm, clear water such as the Pacific and the Indian Ocean, where they grow best. This is why there are no coral reefs on the west coast of South Africa. However, South Africa’s east coast offers much brightly coloured sea life.
In South Africa more than 100,000 dives a year are made just in coral reefs, which are one of the natural wonders of the world. To see the whole beauty of the reef the right diving gear(设备) is an essential requirement. This means a perfect fitting diving mask and fins, as well as a snorkel(呼吸管)and a friend. Diving alone is dangerous because there may be strong currents you are not aware of, and it’s a lot more fun to share the experience with someone. However, before you can explore the deeper sea, a certificated and checked scuba, a wetsuit and of course a license will be needed. Whether you choose the snorkel or the scuba to spot the colourful underwater world, try to touch as little as possible, be careful with the corals and don’t strike the fishes, because the complex ecosystem is very sensitive.

Sunny countries are often poor. A shame, then, that solar power is still quite expensive. Eight19, a British company by Cambridge University, has, however, invented a novel way to get round this. In return for a deposit of around $10 it is supplying poor Kenyan families with a solar cell able to generate 2.5 watts of electricity, a battery that can deliver a three amp(安培) current to store this electricity, and a lamp whose bulb is a light-emitting diode(二极管). The firm thinks that this system, once the battery is fully charged, is enough to light two small rooms and to power a mobile-phone charger for seven hours. Then, next day, it can be put outside and charged back up again.
The trick is that, to be able to use the electricity, the system's keeper must buy a scratch card—for as little as a dollar—on which is printed a reference number. The keeper sends this reference, plus the serial number of the household solar unit, by SMS to Eight19. The company's server will respond automatically with an access code to the unit.
Users may consider that they are paying an hourly rate for their electricity. In fact, they are paying off the cost of the unit. After buying around $80 worth of scratch cards—which Eight19 expects would take the average family around 18 months—the user will own it. He will then have the option of continuing to use it for nothing, or of trading it in for a bigger one, perhaps driven by a 10-watt solar cell.
In that case, he would go then through the same process again, paying off the additional cost of the upgraded kit at a slightly higher rate. Users would therefore increase their electricity supply steadily and affordably.
According to Eight19's figures, this looks like a good deal for customers. The firm believes the average energy-starved Kenyan spends around $10 a month on oil—enough to fuel a couple of smoky lamps—plus $2 on charging his mobile phone in the market-place. Regular users of one of Eight19's basic solar units will spend around half that, before owning it completely. Meanwhile, as the cost of solar technology falls, it should get even cheaper.
