I go in a secondary school in the ninth grade and I writing a skilled work in the subject geography. I have choose the topic ,,Yellowstone National Park" and I have already written the theoretical part of this. Now I am going to prepare the practical part and for that I have the idea to make a short interview. I only have a few questions so if you have got time for these I am looking forward to your answer. These are the questions: 1. There was a big forest fire in 1988 and first the most people think it was a disaster. But then the scientists know that the fire had a positive effect of the ecological balance. What had the fire improved and how had the population of the plant species changed? 2. 600.000 years ago was the last big eruption of the Yellowstone Vulcan. What would a eruption like this do in our world today? 3. Which seismographic moves are there right now? 4. The scientists don´t think that a volcanic eruption is now to await, but which factors can be change this situation quickly? 5. Recently have the park problems with the bison outside of the protected area. The farmers don´t want them because of their illness. Are there any changes in the conflict? 6. What do you think are the most interesting attractions for the tourists in the park?
