Slide 9: Conclusion

All of these species, which contribute to the biodiversity of the Alaskan Tundra, are in risk of becoming extinct. Climate change, caused by humans, is destroying this unique and valuable ecosystem one animal at a time. The biodiversity of the whole world will be severely damaged if action is not taken to save these animals, many of which are only found in the arctic region.

Slide 8: Red knot

The red knot is the one of the most amazing birds in the Alaskan Tundra, but sadly are becoming extinct. 4 out of 6 populations are dying out. Crabs they are eating are dying out because of climate change, which is making the Red Knot population decrease.

Slide 7: Arctic Char

The Alaskan Tundra is home to 70% of the world's freshwater. The arctic char is one of the only fish able to survive in these conditions, however. Though populations of this fish are relatively healthy, over fishing and the climate change could easily lead to the loss of this important part of the arctic ecosystem.

Slide 6: reindeer and caribou

The reindeer and caribou are large dominant mammals living in the Alaskan Tundra. They both provide a good resource for the people living in the Arctic, who depend on the success of the population. Climate change can negatively affect the animals. 

Slide 5: Ivory Gull

The Ivory Gull is another animal that will suffer if the polar ice continues to melt. This unique bird follows the polar bear. It survives off the leftovers of the predator. If the polar bear suffers, the ivory gull will be in great danger.
