Werewolf: The Apocalypse has always had ecological subtext, given that you're basically Gaia's superpowered children fighting against an evil corporation of polluters, but some writers handle it worse than others. In The Silver Record's prologue, for example, the plot stops for an entire paragraph just so the reader can be informed that everyone who lives in the modern world is a heartless, egocentric bastard.
But y’see, science is a double-edged razor. It provides us with better ways to feed ourselves, protect ourselves, and move from place to place, but it also breeds isolation and a “me-first” mentality. When people— Garou included — don’t feel like they have to struggle to survive, they get soft and selfish. After a while, everyone starts feeling like the lead in their own personal movie. Everyone and everything else in the world becomes supporting cast and background material. At that point, nothing is good unless it enriches you. Unless it makes your life safer, more comfortable, more fun. Don’t shake your head, you know I’m right! After a while, nothing in this world matters unless it somehow makes you feel better! Now multiply that by the amount of people in the world today, square it by the economies of nations, and subtract any sort of feeling of community or family. Our family tree is dying — literally! — because we don’t feel or feed its roots any longer.
