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.
