Biome: Environmental Science

A four-year environmental science curriculum, offline, with no account and no network. Biome covers an introductory sequence and the first two years of a degree: the physical Earth and ecology first, then water, air and pollution, then energy, population and health, then climate, policy and futures. WHAT IS INSIDE 100 lessons across four years, each 15 to 25 minutes, with on-device narration 60 researcher profiles, from Humboldt and Carson to Keeling and Hansen 672 glossary terms, cross-linked to the lessons that use them 20 quizzes with worked explanations for every answer 18 landmark cases the field learned from: Minamata, Love Canal, Bhopal, the ozone hole, Flint Spaced repetition that schedules the terms you keep forgetting Bookmarks and notes on any lesson, profile or term Three Home Screen widgets: a quote, a term and a figure, each changing daily HOW IT TEACHES The course is quantitative where the subject is quantitative. Energy return on investment, dose-response curves, residence times, discount rates and attribution statistics all appear with numbers rather than adjectives. It also separates what is settled from what is not. That the planet is warming and that humans are the cause is settled, and the lesson on attribution shows how that was established rather than asserting it. Climate sensitivity, the social cost of carbon and the safety of nuclear power are genuinely contested, and those lessons give the range of positions and the evidence behind each. FREE AND PAID The first ten lessons are free. One purchase of $9.99 unlocks the remaining 90 and everything else, permanently. There is no subscription, there are no ads, and there is no account to create. Family Sharing is supported. OFFLINE BY DESIGN The app makes no network connections. Every lesson, profile, glossary entry, quiz and case study is bundled in the download, so the whole course works in airplane mode. Nothing you read or write here leaves your device.
