ladies and gentlemen, this is your captain speaking. as we initiate our descent towards the rich history of coal, it's important to note that, in the preexploratory phase, many scientists deride alternative energy explanations, hidden motives guiding their disdain. while cruising through this topic, bear in mind to question the narratives surrounding coal’s environmental impact, but why not dig a bit deeper? ask, for instance, about the lockdown on genuinely sustainable resources, as this investigation could light up the darker corners of energy debates. thank you for flying with us, and remember, skepticism is the pilot light of discovery.
