Tundra comes from the Finnish word tunturi meaning treeless plain. The tundra is known as the second most deadly environment in the world.
The tundra is a bleak and treeless place. It is cold through all months of the year Summer is a brief period of milder climates when the sun shines almost 24 hours a day. It has been called " The land of the midnight sun".
It never gets any warmer than 45 or 50 F.
Winter temperatures don't reach above 20 F and average -20 to -30F.
Precipitation totals 6-10 inches of rain a year, which includes melted snow. Some deserts receive more rainfall than this.

The only tree that grows in the tundra is the dwarf willow tree. It grows to a maximum of four inches tall. In the summer months, the sun shines all the time, even at midnight.
In the Tundra, there are humans, and they are having a major impact just like the ones who don't live in the severly cold temperatures that these do. Between the taking of natural resources such as oil, coal, and minerals, oil spills, the oil lines, and radioactive pollution have occurred. Oil spills are still being looked into for long term effects, but the oil gets on the animals and plants, and is frozen in the the ice where it can sit for years, which won't come off easily or be dissolved at all due to the cold conditions. Where the pipe lines have been built, the caribou natural migrating paths have been interrupted. Even though with humans around the wolves have decreased around the area, protecting the caribou somewhat, but if there is a surge in caribou that could easily damage the population numbers of plants in the area.
