Invest in Earth
Biomass can be burned for a boost now, or spent rewilding the land. The slower choice is the one that compounds.

Time Value of Money says that money grows (or quietly loses value) depending on what you do with it over time, but that's an abstract claim until you've actually watched it play out. Invest in Earth turns it into something living: you manage an ecosystem where biomass is your only resource, and every unit can either be burned in a reactor for an immediate boost, or spent rewilding the land around you. Burning gives you a payoff right now; rewilding gives you a slower start but a steadily growing return, as the ecosystem regenerates and eventually produces more biomass than you originally put in. That's the same logic behind investing money instead of spending it, value grows the longer it's given room to compound, and burning through resources today costs you the larger return you would have earned later. No financial language appears while you play; the tension is felt entirely through the health and growth of your grid. Afterward, the reveal connects the dots explicitly: reactor burn maps to spending, rewilding maps to investment, and ecosystem growth maps to compound returns over time.
