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. Also, from nuclear testing and reactor accidents there has been radioactive pollution. The pollution has been trapped in glaciers which have been melting, and running off onto plants and possible food sources for the entire biome. This could cause food poisoning for everything up there. It would also take the vegetation years, if not decades, to recover from such a blow.

This is actually the dumbest answer possible. The inability to convey their thoughts gives the image that the author of said answer is either dyslexic or has an IQ of, oh, say, 53. Nuclear testing? Seriously? What tabloid did that information from? Someone obviously needs to learn the difference between a conspiracy theory and hard fact. Nuclear testing. Why would any country do that, when the land has been set aside by the UN for research that doesn't involve any sort of radioactive material.

--I found multiple problems with the first answer and I will list them here:

-Oil Spills: They affect every biome- not just the Tundra specifically. Even so, the oil would be affecting the coastal tundra regions- not crawling inland and affecting the plants and animals there. There are quite a few animals that live deeper inland from the coast- like caribou.

-Natural Resources: They are not essentially being minedin the Tundra specifically. Many leading energy companies have developed unsustainable methods of withdrawing natural resources but countermeasures are being taken or will be taken in the near future.

-Pipelines and caribou: A pipeline is built. So what? The caribou finds a way around it. Scientific leads have been pointing to a more imminent danger to caribou- and the rest of the environment- human-caused climate change. Before someone goes off on a rant concerning climate change- consider the word science there. Science is mere observation. It's deduction. One of the critical limitations of science is that it cannot bring about truth. I myself am not a particular advocate of climate change. With that aside, I continue by stating that recent scientific discoveries have pointed to climate change as a critical killer of caribou. Numbers have been dwindling due to the increasingly extreme summer and winter temperatures and conditions in the Tundra. Mosquitoes and other species that don't usually reside in that environment are a pest in the summer. The winter brings about devastating blizzards, a thicker permafrost, more precipitations (thicker mats of snow), making food scarce for the caribou and living conditions miserable overall. For further information on that subject, I would suggest watching the National Geographic's "Strange Days on Planet Earth" episode concerning climate change and the environment. (I forgot the exact episode number and title)

-Nuclear Testing: Ok, so Chernobyl (Oh wait, that wasn't even a test- it was an accident. Wait, is that even within the Tundra at all? Biome maps say no.). What other specific incidents of Nuclear Testing being an issue are there? Yes, there's the ozone hole in Antarctica but that's natural- not a man-caused test.

-Wolves and the Caribou: The people who live in the Tundra aren't stupid. They understand the functional benefits of Wolves and Caribou more than many of us who don't live up there. They aren't going to kill them off. So what do you people think is killing the wolves if humans aren't? Are they disappearing from the Tundra like they did in Yellowstone? Are they disappearing at all?
