What is a wilderness? A wilderness is an area of land that hasn’t been significantly changed by humans. Wildernesses are the last really wild places on Earth. Until recent times, people only affected quite small areas of the planet, and most of the earth was wilderness. The wilderness was something to be afraid of, full of wild sts animals that could kill you, fores forests where you could become hopelessly lost, and icy mountains where you could fall to your death.

Why should we preserve wildernesses? Wildernesses have taken millions of years to develop, and the plants and animals that live there have become highly adapted. Many can’t live anywhere else. For instance, orangutans are only found in the rainforests
Rafflesia arnoldii
of Borneo and Sumatra, and Rafflesia arnoldii – the largest flower on Earth – is only found in the rainforests of Sumatra, Indonesia and Malaysia.
