Crop growth is very difficult in tundras due to the permafrost conditions. This means that there is little to no wheat resources for the feeding of animals such as cows and sheep. The little arable land additionally creates unsuitable conditions for other plants that aren't weeds or lichens, which need little nutrition from the soil.
Normal livestock grown in regular biomes, like a plain biome, is impossible due to the too-cold conditions, plus the fact that the main foods these animals need cannot be grown. The main animals farmed here are deer, which are adapted to survive these conditions. Additionally, aquaculture is gaining popularity because fish farming can be done in a small amount of space.
The supply chain is fueled in tundra biomes by using aquaculture and deer farming. These are the only ways to get food in these areas because of a lack of arable land for normal crop production.
Production in tundra forests is normally deer farming and aquaculture.
The meats produced using these methods are processed the same way as normal meats.
Transport is normally done using boats as there are few roads in the tundras and no landing areas.
A lot of places offer venison in their meat aisle, and fish in the fish aisle.
Consumers buy venison for its nutritional benefits and fish for its unique tastes.
