I believe each one of the components is achievable if we bring awareness to cities around the globe. Resource efficiency can be achieved by new technology. Conserving and recycling water and energy is essential for the quality of life of an individual. Basic needs such as access to clean and consumable water, as well as other fundamental priorities in urban areas is important for our health and well being. Environmental cleanliness takes effort from all of the citizens that inhabit the city. Bringing awareness by promotion and ads can also help this cause.
