Sustainability means using resources in a way that meets our needs without harming the ability of future generations to meet theirs. It involves balancing environmental care, social well-being, and economic growth. For example, using renewable energy like solar or wind power helps reduce pollution and slows down climate change, making the planet healthier for both people and nature.

A key part of sustainability is reducing waste and conserving natural resources. This can be done by recycling, reusing items, and saving water and energy in our daily lives. Schools, homes, and businesses can all take steps to be more sustainable—like using LED lights, planting trees, or avoiding plastic. Small changes, when done by many people, can make a big difference.

Sustainability is not just about the environment—it also means treating people fairly and making sure everyone has access to clean water, education, and good jobs. By supporting sustainable practices, such as buying from eco-friendly companies or using public transport, we can help build a better, more equal world. In short, sustainability is about protecting the planet and improving life for all living beings.
