Water cycle, intervention

The aim of the Life Cycle Impact Assessment (LCIA) is to facilitate the interpretation of the results of the inventory analysis. The result of the inventory analysis is an emission profile for each alternative system. In this study the emission profile is the total of all emissions to air, water and soil from the grave-to-cradle chain for the use of cushion vinyl floor covering, including the up chain processes, like electricity production and the down chain processes, like the incineration and landfill of the waste. Such an emission profile may consist of hundreds of emissions and extractions. In LCA impact assessment the total of interventions (emissions, extractions) of a process chain is evaluated in terms of environmental problems (impact categories). 

The positive aspects of the sea for society include the availability of abtmdant river water for human settlement and economic development purposes, for example, fertile but dry soils can rely on the water supply in the region. There has been, until recently, a sustainable balance of the Aral Basin, and therefore the sea s hydrological cycle that is, before human intervention disrupted that cycle.
