Scientists have discovered that moss is one of the most powerful natural climate tools on Earth, capable of absorbing four times more CO₂ than trees while requiring no soil, fertilizer, or special care. Despite its incredible environmental benefits, moss is often removed from buildings and sidewalks — even though it could be a major ally in cooling and cleaning our cities. • Moss captures CO₂ far more efficiently than most plants thanks to its unique leaf structure and extremely high surface-are
