Biodiversity refers to the variety of life on Earth, from the smallest microorganisms to the largest mammals. It is essential for maintaining the balance of ecosystems. Protecting biodiversity involves conserving habitats, planting native species, and reducing pollution. Students can participate in local conservation projects, such as planting trees or creating wildlife gardens in their schoolyards. By understanding and valuing the diversity of life around us, we can take steps to protect it. For example, a school in Brazil created a butterfly garden that now hosts over 20 species of butterflies, providing a safe haven for these beautiful insects.
