The growth in air transportation volume has important global environmental impacts associated with the potential for climate change. On local to regional scales, noise, decreased air quality related primarily to ozone production and particulate levels, and other issues, such as roadway congestion related to airport services and local water quality, are all recognized as important impacts.

When many people first think about building a green home, it is the materials and products that come to mind: insulation made from recycled newspaper and decking made from recycled plastic, for example. Product selection is an important part of green building, but it is generally not as important as energy performance or where the house is built (to minimize automobile use and protect natural areas), or measures to ensure a healthy indoor environment.

The ecological footprint definition is a measurement that compares rates of human resource consumption and waste generation with the biosphere’s rates of resource regeneration and waste assimilation, expressed in terms of the area necessary to maintain these flows. Ecological footprints represent the biologically productive space required to produce the resources and absorb the wastes of a given population, organization, or product using prevailing management and technology.

In the beginning, human progress was limited by the amount of work in single day. This is only to feed themselves and their families. At that time, the economy was largely rural as a result. In the early of 19th century, more intelligent human began to looking for energy resources to support their lives. They began to develop coal, oil, and other stored energy to supplement their prime energy source: sunlight. Sunlight energy results in overgrown plant and animal growth over huge and dispersed areas and geologic time periods. There was, and will continue to be, abundant solar energy sources available to get more fossil fuel, to do research on how to exploit these resources more efficiently, and to use them in daily life and changing their cultures.
