The ecosystems of our planet are becoming ever more endangered. Over 1 million animal and plant species are now threatened with extinction — more than ever before in human history. We need to remind ourselves of the priceless value these ecosystems hold to all of us before it’s too late.

Span created the Terraria project to turn ecosystems into collectables. 3D terrariums emerge from custom letterforms, each containing one of nine different biomes — grasslands, wetlands, mountain, tundra, rainforest, stream, desert, ocean, and forest. NFTS of each biome can be minted based on your transaction, each varied with multiple weather and time-of-day variations as well as rarities.
