In Alaska the Porcupine River herds of caribou have been the basis of the Gwich’in tribes’ survival. This tribe relies on the crossing of the caribou for food, warmth and nourishment. Since 1989 over 600,000 caribou have disappeared due to the rising temperature of the area. Elders of the village are worried that the animals won’t adapt to the climate change fast enough. One of the biggest problems caribou face are mosquitoes, which can suck up to a tablespoon of blood out of the caribou daily. Caribou are forced to graze on top of mountains to avoid the mosquitoes causing them to exert more energy climbing the rough terrain. The rising temperature has caused more snow, causing caribou to have to dig for their food and put them a vulnerable state to predators like wolves. If the weather in the region doesn’t change the herd won’t recover which will result in the impoverishment of the Gwich’in tribe.
Zoaplankton and many other marine lives are also affected by the rising temperature in the oceans. Crabs in tide pools are almost at their threshold with the warmer waters, creating a scare that if they are to rapidly crash in population, it will have an extreme affect on the food chain in the tide pools.
