I do not live in a tent, but a dormitory room. The warmest temperatures I have seen were near 40 degrees. It is currently Spring, and the temperatures are warming up. We have a greenhouse for a small amount of fresh food. The heavy food like canned and frozen food is brought in once a year by ship.
Fresh food is brought in during the summer on the transport planes.
You said that no plants grew in Antarctica except for whats in a green house. But actually plankton and algae can grow in Antarctica and since both are plants that means that plants can grow in cold places. Just thought I would tell. From, Chris Wallis Canyon Middle school Chris, I do not know if plankton or algae are here, possibly in the water. I feel I properly answered the question, please read it again.
