Summary for Policymakers

gas stream and the higher pressure make the separation easier Oxyfuel combustion is in the demonstration phase7 and uses high purity oxygen This results in high CO 2 concentrations in the gas stream and hence in easier separation of CO 2 and in increased energy requirements in the separation of oxygen from air (Sections 3 3 3 4 3 5) 6

The habitat generally consists of humid wooded areas with abundant leaf litter and loose rocks often the lizard occurs in the vicinity of springs swamps and bogs but it also inhabits clearcuts highway and powerline rights-of-way (Hulse et al 2001) rocky bluffs above creek valleys dry rocky south-facing hillsides (Johnson 2000) and dry shale barrens (West ia)

24 11 2016Introduction In 1912 in a paper presented to the Geological Society of London Walter Henry Hardaker described fossils including a series of tetrapod footprints and trackways from what were then considered Permian rocks near Birmingham in the British Midlands

Environmental problems accompany coal on its way from the mine to the point of utilization and beyond Health aspects related with coal mining and coal utilization are also included because in planning for coal use it is impossible to separate environmental and health issues from the discussion of coal utilization

Coal mining particularly in the case of open-cut mines requires that large areas of land are temporarily disturbed and perhaps withdrawn from other productive uses such as agriculture while the process of coal extraction is under way The land may however be returned to productive use after mining or even while mining in other parts of the area is still in progress
