Which statement best defines the concept of environmental sustainability?

The concept of environmental sustainability is best defined by the statement that emphasizes assuring the creation and use of a built environment that does not harm the natural environment. This definition highlights the fundamental principle of environmental sustainability, which is to ensure that human development and activities preserve the ecological balance and minimize negative impacts on the planet.

Environmental sustainability involves practices that facilitate responsible management of resources, promote energy efficiency, and reduce waste and pollution. By focusing on the built environment, this definition captures the essence of sustainable development, which seeks to meet present needs without compromising the ability of future generations to meet theirs. Therefore, adopting designs and practices that protect and enhance natural ecosystems is a core aspect of sustainability.

The other choices focus on concepts that, while related to operations and maintenance, do not encapsulate the broader idea of environmental sustainability. Some deal with specific technical processes or comparisons that do not align with the fundamental goals of sustaining environmental health and integrity.
