Greener Grass

Greener Grass is a free data-exploration app that scores countries by weighted criteria — climate projections, human development, political freedom, and psychedelic-medicine legality — and colors a world map with the results. No account or login is required. To test: open the Overview pane and drag the four importance sliders; the map and ranked list update live. In Deep Dive mode, toggle analysis layers such as projected temperature, democracy indices, or medicine-legality scores, and tap any country to see its detail card. The sea-level rise section has an on/off toggle and a 0–60 m slider driven by public elevation data; note it appears only when zoomed in past a certain level (a tooltip explains this). All drug-legality content is informational only — sourced from the V-Dem Institute, UN Human Development Report, and UNDP Human Climate Horizons — and the app provides no medical or legal advice. Note: the app's drug-legality content is informational only. It describes how psychedelic medicines are regulated in different countries and is never an encouragement to use any substance. It is not medical or legal advice.
