"The atmosphere of Earth is a layer of gases surrounding the planet Earth that is retained by Earth's gravity. The atmosphere protects life on Earth by absorbing ultraviolet solar radiation, warming the surface through heat retention (greenhouse effect), and reducing temperature extremes between day and night (the diurnal temperature variation).
The common name given to the atmospheric gases used in breathing and photosynthesis is air. By volume, dry air contains 78.09% nitrogen, 20.95% oxygen, 0.93% argon, 0.039% carbon dioxide, and small amounts of other gases. Air also contains a variable amount of water vapor, on average around 1%. Although air content and atmospheric pressure vary at different layers, air suitable for the survival of terrestrial plants and terrestrial animals currently is only known to be found in Earth's troposphere and artificial atmospheres."

This cycle diagram sample was created on the base of the figure illustrating the article "Environmental Materials" by Cris Arnold from the website of the UK Centre for Materials Education of the Higher Education Academy. "The figure ... schematically shows how the disparate areas under the heading of 'environmental materials' can be linked via a life cycle analysis approach. ...
Life Cycle Analysis.
Life Cycle Analysis is essentially a method of considering the entire environmental impact, energy and resource usage of a material or product. It is often known as a 'cradle-to-grave' analysis and can encompass the entire lifetime from extraction to end-of-life disposal. Life cycle analysis can be an extremely effective way of linking many different aspects of the environmental impacts of materials usage. ...
Materials Extraction and Resource Implications.
The environmental impact of raw materials extraction and processing together with global resource issues provides a good place to start consideration of environmental aspects of materials. ...
Environmental Impacts of Processing.
... Topics that would come under this subject area include the specific environmental problems associated with processing of metals, polymers, ceramics, composites etc, and how these problems can be overcome.
Design for Sustainability.
This area ... will ... cover issues such as design for successful recycling, waste minimisation, energy efficiency and increased lifetime.
Economic, Social and Legislative Issues.
... For example, materials selection within the automotive industry is now heavily influenced by 'end-of-life vehicle' and 'hazardous material' regulations.
Use of Sustainable Materials.
... It is probably sensible to define such materials as those that have distinct differences that achieve environmental benefit compared to conventional materials. With this definition, the list would include:
(1) Materials of a significantly plant-based nature, including wood, natural fibre composites, natural polymers.
(2) Materials produced using a large proportion of waste material, including recycled polymers, composites made from waste mineral powders, and arguably also much steel and aluminium.
Materials for Green Energy.
The most exciting developments in Materials Science are in the realm of functional materials, and many of these serve an environmentally-beneficial purpose, particularly in the production of green energy.
These include:
(1) Solar-cell materials.
(2) Fuel-cell technology.
(3) Catalytic pollution control.
End-of-Life Issues.
The treatment of materials at the end of their lifetime is a significant subject area and encompasses aspects such as recycling techniques and materials limitations, biodegradabilty and composting, chemical recovery and energy recovery." [materials.ac.uk/ guides/ environmental.asp]
