Step-by-step explanation:
Sustainability involves conducting activities so as to provide for the long-term well-being of the natural environment, including all biological entities.
According to the National Resource Council, sustainable development is the reconciliation of society's developmental goals with its environmental limits over the long term. It involves meeting the basic needs of humans while protecting the planet's resources and cultural and natural diversity. Indigenous peoples view sustainable development as a process that integrates spiritual, cultural, economic, social, political, territorial, and philosophical ideals.
The ecological sustainability of human ecosystems depends on the patterns of flow of energy and materials in the biophysical system. It involves managing inputs of materials and energy sources and outputs of waste products. A sustainable solution is one that can be continued without using up non-renewable resources.
