Final answer:
To purchase foods with low energy input, consumers can choose locally sourced products and avoid processed foods.
Step-by-step explanation:
As consumers, we can purchase foods that require a low energy input by:
- Choosing locally sourced products: By opting for foods that are grown or produced locally, we can reduce the energy required for transportation and minimize carbon emissions.
- Avoiding processed foods: Processed foods often require more energy for their production and packaging compared to fresh and unprocessed foods.
By following these practices, we can make more sustainable and energy-efficient choices in our food consumption.
