Food waste is a major issue impacting sustainability and the environment. Wasted food contributes to **greenhouse gas emissions**, as decomposing food in landfills releases methane, a potent greenhouse gas. Additionally, food waste wastes the resources used in production, such as **water**, **energy**, and **land**. Reducing food waste involves strategies like **improving supply chain efficiency**, **better food storage**, and **educating consumers** about portion sizes and expiration dates. **Composting** and **donating excess food** also help minimize waste. Addressing food waste is crucial for enhancing sustainability, conserving resources, and reducing environmental impacts while improving food security.
