Grass is more than a simple plant. Every square meter of lawn quietly does many jobs at once: it cools the soil by 2.3 °C, banks 4.5 tons of CO₂ each year, and even writes tiny daily news in its own green ink. In 2022, the journal *Nature Plants* reported that a single hectare of grass works like a 1.4-megawatt solar farm, storing sunlight as chemical energy. This short article shows 30 easy metaphors that help us see these hidden talents—in numbers we can all understand.
