Resource usage refers to how we consume various materials and services to meet our needs. This can include natural resources like water, minerals, and forests, as well as human-made resources such as energy and technology. Efficient resource usage aims to minimize waste and ensure that these resources are available for future generations. Monitoring resource usage is essential for sustainability. It helps identify areas where consumption can be reduced or managed better. By understanding our environmental impact and adopting practices like recycling and conservation, we can improve our quality of life while protecting the planet.
