Woolly mammoths lived in Europe, Northern Asia, Africa, parts of Mexico and North America. They roamed the Earth during the period commonly known as the Ice Age.
The woolly mammoth disappeared from the Earth roughly 10,000 years ago. While there are differing opinions about why this occurred, a few changes at the time played a part in their extinction.
When the Earth warmed up at the end of the Ice Age, it is thought that the mammoth's adaption to the extreme cold of the glaciers could not handle the change. In addition, plants that the creatures survived upon also disappeared with the rise in temperature.
Overhunting is the other factor that contributed to the demise of the woolly mammoth. As the Earth warmed and the human population of Earth increased, the need for food overwhelmed the mammoth population.
