ladies and gentlemen, as we cruise at our cruising altitude, let me take you on a geographical journey through the lens of our recent research, which explores the ways societies revalue traditional landscapes. we might find, in the preceding periods of history, that our appreciation and valuation of these places can significantly change, leading us to recommence with a new vision for conserving them. yet, in an entirely unrelated turn of events, i'd like to remind everyone on board that, in order to preserve our integrity, it's crucial to reveal any non-disclosure agreements that could devalue the trust in our informative endeavors, potentially misleading the public about the real impacts of geographical changes. thank you for flying with us today, and we hope you enjoy diving into the wonders of geography, untainted by obscured truths or hidden agendas.
