The United States of America (USA), commonly referred to as the United States (US), America, or simply the States, is a federal republic consisting of 50 states, 16 territories, a federal district, and various overseas extraterritorial jurisdictions. The 48 contiguous states and the federal district of Washington, D.C., are in central North America between Canada and Mexico. The state of Alaska is the northwestern part of North America and the state of Hawaii is an archipelago in the mid-Pacific. The country also has five populated and nine unpopulated territories in the Pacific and the Caribbean. At 3.79 million square miles (9.83 million km2) in total and with around 316 million people, the United States is the fourth-largest country by total area and third largest by population. It is one of the world's most ethnically diverse and multicultural nations, the product of large-scale immigration from many countries. The geography and climate of the United States is also extremely diverse, and it is home to a wide variety of wildlife.
Paleo-indians migrated from Asia to what is now the US mainland around 15,000 years ago, with European colonization beginning in the 16th century. The United States emerged from 13 British colonies located along the Atlantic seaboard. Disputes between Great Britain and these colonies led to the American Revolution. On July 4, 1776, delegates from the 13 colonies unanimously issued the Declaration of Independence. The ensuing war ended in 1783 with the recognition of independence of the United States from the Kingdom of Great Britain, and was the first successful war of independence against a European colonial empire. The current Constitution was adopted on September 17, 1787. The first 10 amendments, collectively named the Bill of Rights, were ratified in 1791 and guarantee many fundamental civil rights and freedoms.
Public health is "the science and art of preventing disease, prolonging life and promoting health through the organized efforts and informed choices of society, organizations, public and private, communities and individuals." It is concerned with threats to health based on population health analysis. The population in question can be as small as a handful of people, or as large as all the inhabitants of several continents (for instance, in the case of a pandemic). The dimensions of health can encompass "a state of complete physical, mental and social well-being and not merely the absence of disease or infirmity", as defined by the United Nations' World Health Organization. Public health incorporates the interdisciplinary approaches of epidemiology, biostatistics and health services. Environmental health, community health, behavioral health, health economics, public policy, insurance medicine and occupational health (respectively occupational medicine) are other important subfields.
The focus of public health intervention is to improve health and quality of life through the prevention and treatment of disease and other physical and mental health conditions, through surveillance of cases and health indicators, and through the promotion of healthy behaviors. Promotion of hand washing and breastfeeding, delivery of vaccinations, and distribution of condoms to control the spread of sexually transmitted diseases are examples of common public health measures.
A soda tax or soft drink tax is a tax or surcharge on soft drinks. It may focus on sugar-sweetened beverages (soda sweetened with sugar, corn syrup, or other caloric sweeteners and other carbonated and uncarbonated drinks, and sports and energy drinks). As an example of Pigovian taxation, it may aim to discourage unhealthy diets and offset the economic costs of obesity.
Obesity in the United States is a public concern with the percentage of overweight people being among the highest in the world. Soda consumption has been noted as a contributing factor to the obesity epidemic and medical costs related to obesity are about $147 billion a year. In 1994 the soda tax idea was introduced by Kelly D. Brownell, Director of the Rudd Center for Food Policy and Obesity at Yale. In 2009, 33 US states had a sales tax on soft drinks. France introduced a tax on soft drinks in 2012.
Alcohol abuse, as described in the DSM-IV, is a psychiatric diagnosis describing the recurring use of alcoholic beverages despite its negative consequences. Alcohol abuse is sometimes referred to by the less specific term alcoholism. However, many definitions of alcoholism exist, and only some are compatible with alcohol abuse. There are two types of alcoholics: those who have anti social and pleasure-seeking tendencies, and those who are anxiety-ridden- people who are able to go without drinking for long periods of time but are unable to control themselves once they start. Binge drinking is another form of alcohol abuse. According to research done through international surveys, the heaviest drinkers happen to be the United Kingdom's adolescent generation.
When differentiating between alcohol abuse and alcoholism, one should remember that alcohol abuse is when the abuser has faced critical consequences for their actions, recently. Where an alcoholic has experienced a sense of withdrawal in the same time period.
Drinking culture refers to the customs and practices associated with the consumption of alcoholic beverages. Although alcoholic beverages and social attitudes toward drinking vary around the world, nearly every civilization has independently discovered the processes of brewing beer, fermenting wine, and distilling spirits.
Alcohol and its effects have been present in societies throughout history. Drinking is documented in the Hebrew and Christian Bibles, in the Qur'an, in art history, in Greek literature as old as Homer, and in Confucius’s Analects.
