Obesity and chocolate consumption seemingly have no proven correlations. Yet, in this essay, many chocolate focused arguments have been presented, including the transient effect of chocolate on mood and the fact that it is as likely to create feelings of guilt as of well-being. Another possible positive dimension to chocolate is a correlation with cardiovascular health. Yet the potential benefits of flavanols in chocolate are currently offset by the high fat/carbohydrate content of most forms of chocolate. Whether chocolate is a food or a drug is also unclear. The literature outlines the chemical properties of chocolate which could help explain some addictive type behaviour, particularly in regards to nervous tension in women, but there is also a strong research focus on chocolate as a sensory-based indulgence. It can therefore be said that chocolate is not a healthy food, but can be enjoyed as part of a healthy and balanced diet and lifestyle.
Nearly half of alcohol-related deaths are the result of motor vehicle crashes, falls, fires, drowning, homicides, and suicides. 19 Alcohol use is associated with 1/3 of all suicides. 20 There were approximately 79,000 deaths annually for the years from 2001–2005 that were attributable to excessive alcohol use, mostly from alcohol-related traffic accidents. 21 708,000 persons are injured in alcohol related car crashes every year, and 74,000 of those suffer serious injuries. 22 The burden of untreated alcohol abuse and dependency is enormous.
They worry more about smaller, chronic leaks that would defeat the purpose of the enterprise. Geophysicists Mark Zoback and Steven Gorelick of Stanford University argue that at sites where the rock is brittle and faulted—most sites, in their view—the injection of carbon dioxide might trigger small earthquakes that, even if otherwise harmless, might crack the overlying shale and allow CO₂ to leak. Zoback and Gorelick consider carbon storage “an extremely expensive and risky strategy.” But even they agree that carbon can be stored effectively at some sites—such as the Sleipner gas field in the North Sea, where for the past 17 years the Norwegian oil company Statoil has been injecting about a million tons of CO₂ a year into a brine-saturated sandstone layer half a mile below the seabed. That formation has so much room that all that CO₂ hasn’t increased its internal pressure, and there’s been no sign of quakes or leaks.
