The aspect that you must consider when listening to the position of the worker of the national energy company is that its opinion could be biased.
He is speaking on behalf of the company. The company has its business interests and has invested millions in this project. Probably, its arguments are not totally true and are is just trying to convince people and the officials.
Why is important here is that you could ask key questions such as if there is a neutral revision or neutral agency that could confirm that no damage is going to be done to nature. Or you could ask for the intervention of EPA, the United States Environmental Protection Agency that takes care of the environment. You could demand a third-party expert opinion to really confirm that the Energy company is not biased, and it's not going to cause any harm.
