When we talk about transport, most people think of buses, cars, bicycles and so on. But in some parts of the world, animal transport is as popular as these modern types of transport, and sometimes more popular. Because at certain times of year, animals are the only way to travel. Take the desert for example, with its 50-degree temperatures. Yes, you can cross it in the right vehicles, but for long distances, modern vehicles are not as good as camels. A camel can travel over 40 kilometres per day and go without water for three to five days. Yes, it's slower, and maybe a camel isn't as comfortable as a car. But a camel's big feet make it more reliable in the sand - unlike a car, it doesn't get stuck. Camels are so important in the desert that there are around 160 different ways of saying the word 'camel' in Arabic. In winter, northern Alaska can be as cold as the North Pole. Temperatures go down to minus 50 degrees. Your engine can freeze, and even if your car starts, snow and ice on the road can make driving impossible. When the weather is as bad as this, the only way to travel is by sledge with a team of between six and eight huskies. These famous dogs can pull heavy sledges for hundreds of kilometres. There is even a race for huskies in Alaska called the Iditarod, where large teams of huskies pull sledges over 1,600 kilometres.
