Grass. If there is one plant that has come to dominate our world, it’s this. Occupying every biome on earth except the icesheets, grasses have colonised every patch of soil, from tropical to temperate forests, savannah to steppe, scrubland to desert. Humans have taken these grasses and shaped them over generations into crops that feed the world today. Their homelands are the seas of grass we call Meadow, Prairie, Pampas, Veldt and Steppe – the world’s Grasslands.
