Sustaining refers to the ability to maintain or support a process, system, or resource over time. It involves practices that ensure the longevity and health of various elements, such as ecosystems, communities, and economies. For example, sustainable agriculture focuses on growing food in ways that protect the environment and preserve resources for future generations. In the context of environmental science, sustaining often emphasizes the balance between human needs and the health of the planet. This includes efforts like reducing waste, conserving energy, and protecting biodiversity. By adopting sustainable practices, individuals and organizations can contribute to a more resilient and equitable world.
