<human>:  What are the major benefits of composting?
<bot>: The major benefits of composting are: reducing the amount of waste sent to landfills, providing valuable nutrients for plants and gardens, improving soil structure and health, and creating a natural fertilizer to help plants grow. Composting can also result in reduced water usage as compost helps soil retain moisture. Additionally, composting can have a positive impact on local air quality due to reduced emissions associated with traditional fertilizer-manufacturing processes.
