Which practice is least effective in reducing the use of limited resources?

The practice that is least effective in reducing the use of limited resources is frequent replacement of products. This method leads to the continuous extraction and consumption of raw materials, contributing to increased resource depletion. When products are frequently replaced rather than repaired, reused, or recycled, it creates additional waste and intensifies the demand for new resources, which is not sustainable.

In contrast, reusing products extends their life cycle, recycling materials helps to recover valuable resources and reduce the need for new raw materials, and minimizing consumption directly lowers the amount of resources needed overall. By focusing on reducing consumption and making the most out of existing products, we can have a more sustainable impact on resource usage.
