Grass is a common type of plant that covers many landscapes around the world. It has long, thin leaves and grows in clusters, creating a green carpet on the ground. Grass is important for the environment because it helps prevent soil erosion and provides food for many animals, such as cows and sheep. There are many different types of grass, each suited to various climates and uses. Some grasses are used for lawns, while others are grown for sports fields or as pasture for livestock. Grass also plays a role in ecosystems, supporting insects and other wildlife.
