Unfortunately, music can also cause some serious harm in the form of tinnitus or other permanent hearing loss/damage. Tinnitus can result from listening to music at high volumes or amplitudes. Tinnitus is a buzzing in the ears that ranges from slight to severe. Tinnitus is a highly subjective condition; some patients claim to perceive sounds of animals or even popular songs. Music has also been known to cause epileptic seizures, often resulting in psychiatric complications. In a book devoted to the studying of these rare cases, Oliver Sacks, a professor of clinical neurology at Columbia University, writes of a woman who could not listen to a certain popular song for more than half a minute without succumbing to violent convulsions.
Among the academic community, there is little doubt that fossil fuels are contributing to global warming and climate change. Energy is a requirement for economic progress, and so far fossil fuels have been the main source of energy in most economies. Economic and population growth have contributed to increasing emissions of green-house gases (GHG), including, carbon dioxide (CO2) and chlorofluorocarbons (CFCs), which have led to unprecendented concentration levels of these gases in the atmosphere. Scientists link the concentrations of GHG in the atmosphere with the changes in climate trends recently observed, and, in particular, with the increase in average temperatures on Earth.
In 2009–2010, 21 states and the District of Columbia had at least one in four households with children (25 percent or more) facing food hardship, according to the Food Research and Action Center (FRAC). The District of Columbia had the highest rates of food hardship for households with children, followed by Mississippi, Alabama, Florida, Arkansas, Nevada, Arizona, Louisiana, Kentucky and Tennessee.
