11) The chart below compares the greenhouse gas emissions of several fuel sources. Greenhouse Gas Emissions of Fuel and Energy Sources Fuel > Gasoline Sugarcane Ethanol Cellulosic Ethanol Corn Ethanol Energy > Source Fossil Fuels Biomass Biomass Biomass Source: Adapted from http://energy.itgoverns.com An accurate prediction that could be made regarding the information shown in the chart is that A) fossil fuels emit the least amount of greenhouse gases the use of biomass-based fuels instead of fossil fuels will greatly decrease the production of greenhouse gases B) the use of any one of the ethanol sources for fuel will each produce more greenhouse gases than the use of gasoline for fuel C) D) a total change from gasoline to ethanol as a fuel would have no effect on greenhouse gas emissions Greenhouse Gas Emissions

Environmental health and hazards

An organism's environment is the environment in which it lives and has an impact on its well-being. The World Health Organization (WHO) defines environmental health as "those aspects of public health, such as quality of life, that are influenced by physical, chemical, biological, social, and psychosocial components in the environment." Environmental health is concerned with both natural and man-made settings in order to enhance public health. Environmental science, occupational medicine, toxicology, and epidemiology are the key subdisciplines of environmental health.
