Let’s talk about the tundra. It’s very beautiful! Here’s some subarctic/alpine tundra near the Swedish-Norwegian-Finnish border where I did fieldwork. (1/17) 
Do you see any trees? Nope- there aren’t any in the tundra! The permafrost & climate prevent plants w/ very deep roots from growing. Depending on location are tall or short shrubs (in the pic below). There’s also grass, flowering plants, mosses and lichens. (2/17)
Depending on how you define tundra, it covers a large area of the earth’s land (~8%). It also stores a lot of carbon underground, which is being released with #climatechange. nytimes.com/2017/05/08/cli… (3/17)
