management can affect soil characteristics as well as soil quality. The term soil quality can be defined as the overall activity of a soil within an ecosystem that preserves biological activity and environmental quality‚ thus promoting plant and animal health (Doran et al. 1994). Alterations in soil properties and processes can affect functions that soils perform in the environment‚ which in turn influence patterns of plant growth (Ahuja 2003). Changes in land use influence several soil processes‚ such

The lime industry is a significant carbon dioxide emitter. The manufacture of one tonne of calcium oxide involves decomposing calcium carbonate‚ with the formation of 785 kg of CO2 in some applications‚ such as when used as mortar; this CO2 is later re-adsorbed as the mortar goes off. Additionally‚ if the heat supplied to form the lime (3.75 MJ/kg in an efficient kiln) is obtained by burning fossil fuel it will release CO2: in the case of coal fuel 295 kg/t; in the case of natural gas fuel 206 kg/t

Petroleum‚ in one form or another‚ has been used since ancient times‚ and is now important across society‚ including in economy‚ politics and technology. The rise in importance was mostly due to the invention of the internal combustion engine‚ the rise in commercial aviation and the increasing use of plastic. More than 4000 years ago‚ according to Herodotus and Diodorus Siculus‚ asphalt was used in the construction of the walls and towers of Babylon; there were oil pits near Ardericca (near Babylon)

But over large tracts of the world’s surface the delicate balance(微妙的平衡) between man and nature is still being destroyed by industrialization‚ over-population and the resulting pollution.
