Sustainability means using natural resources wisely so that future generations can also enjoy them. Our Earth gives us air, water, food, and shelter, but careless actions like cutting trees, wasting water, and using plastic harm nature. By planting trees 🌳, saving water 💧, reducing plastic ♻️, and using renewable energy ☀️, we protect the environment. Small actions such as switching off lights, reusing bags, and keeping our surroundings clean make a big difference. If everyone works together, we can create a clean, healthy, and green planet for the future 🌱.
