Ecologically sustainable development aims to meet the needs of the present without compromising the ability of future generations to meet their needs. As the global population and consumption increases, we are straining the planet's resources and experiencing impacts like increased greenhouse gases, salination of land, unsustainable water use, depletion of resources, and loss of biodiversity. As designers and builders, we can incorporate sustainable thinking into construction by considering environmental, social and economic factors, using renewable materials, and minimizing impacts on air, soil and water to help build a healthy environment now and for the future.
