[justify]Today, the way ecology is being incorporated into architecture has evolved considerably. Sustainable architecture, or green architecture, aims to minimize the negative impact of buildings on the environment by enhancing efficiency and moderating the use of materials, energy, and space. Spewing carbon dioxide, generating masses of waste, and consuming alarming quantities of energy and water, our cities place a heavy burden on both the global environment and the local ecosystem. Architecture itself has a tremendous impact on the environment.[/justify]
