PBS/NOVA Predator Invasion Documentay

In my MSED class we recently watched a PBS documentary about predator. This documentary talked about interspecific and inraspecific competition between species and the trophic level pyramid. Interspecific competition is compeition between different species. An example the documentary gave of this was the wolves hunting the moose in Yellowstone Park. Intraspecific competition is competition between the same species. An example of this from the documentary was the moose fighting for food/plants to eat to survive. Since there was an over abundance of moose, they were eating plants faster than the plants could regrow. This created a shortage of food which was causing the moose to die off. This created a competition for food, for survival. It also discussed how predation effects certain species in areas and how introducing animals that didn't originate from a certain area are effected and effect an area when they are brought in. There was a lot of content and information in this video and I learned a lot. One of the things I learned was what the trophic level pyramid was. What this pyramid consists of is at the bottom level you have the producers (plants), then the primary consumers, then the secondary consumers, then at the top you have tertiary consumers. I never knew what this was before but I enjoyed learning about it. This documentary was a great teaching as well as learning tool because it really helped reenforce and explain vocabulary we had been learning in class. Some of the species that were in this documentary were panthers, wolves, and bears! The documentary discussed wolves from Yellowstone Park. It talked about the original wolves that were there, but then also talked about wolves that were introduced to the area from another place. I understand the point of the reintroduction of the species into the area was necessary. It helped the  plant life in Yellowstone flourish because the wolves were eating the moose so there wasn't an overabundance of moose eating all these plants. For that reason I agree with the reintroduction of this species. On the flip side I don't think reintroducing these wolves to the area is ok. They started dying off for a reason, and I think it will just happen again. Reintroducing them into the area just seems like a temporary fix to me. The underlying issue is us as humans and until we fix the way we live our lives, we are going to have to continue to settle with temporary fixes.
