Final answer:
Ann Arbor is combating food waste through composting and educational programs. Composting food waste is generally cheaper than throwing it in the trash.
Step-by-step explanation:
Ann Arbor is combating food waste through various initiatives. One of the key methods is by promoting composting. Composting involves breaking down food waste into nutrient-rich soil that can be used for gardening and landscaping. The city encourages residents to compost their food scraps by providing compost bins and offering educational programs on composting techniques.
In terms of cost, it is generally cheaper to compost food waste than to throw it in the trash. When food waste goes to the landfill, it produces methane, a potent greenhouse gas. Landfill space is also limited and costly to manage. On the other hand, composting reduces the volume of waste going to landfills, mitigates greenhouse gas emissions, and produces a valuable soil amendment.
