Question

Answer 1

Two natural and artificial resources are carbon and sulphur

Answer 2

The US Environmental Protection Agency (EPA) reports that that the major contributors to acid rain are SO2 and NOx, which result from the burning of oil, coal, natural gas, and other fossil fuels. The agency notes that about 70% of SO2 emissions produced in 2006 were caused by fuel combustion by electric utilities using fossil fuel. Fossil fueled industrial facilities contributed 13% to the number. Other, lesser sources were transportation vehicles and industrial processes; highway vehicles being the primary source of NOx emissions, accounting for 36% of the 2006 total. Another 22% was added by off-highway vehicles, like bulldozers, while power plants accounted for 20% of the total.
