Sustainability means using resources in a way that meets are needs without harming the environment or reducing the ability of future generations to meet theirs. It involves protecting nature, saving energy and water, reducing pollution, and using things wisely. For example, using solar energy, recycling waste, planting trees and avoiding plastic are all sustainable practices. Sustainability is important because it helps fight climate change,  keeps our air and water clean, and ensures a healthy plant for all living being. By making small changes in our daily lives to a greener and better world.
