I want to know the answer to the following question:
What was the main concern of Edward Itta?
All the background I'm provided with is that "Around the same time period, a reporter for Fortune magazine spoke with Edward Itta, an Inupiat Eskimo leader and the former mayor of the North Slope Borough, who expressed that he was conflicted about Shell's plans in the Arctic, as he was very concerned that an oil spill could destroy the Inupiat Eskimo's hunting-and-fishing culture, but his borough also received major tax revenue from oil and gas production; additionally, further revenue from energy activity was considered crucial to the future of the living standard in Itta's community.". Is that enough to answer the question?
Answer: yes
