The ten threats identified in 2004 by the High Level Threat Panel of the United Nations are these:

The 100: A Ranking of the Most Influential Persons in History is a 1978 book by Michael H. Hart, reprinted in 1992 with revisions. It is a ranking of the 100 people who, according to Hart, most influenced human history.

The first person on Hart's list is the Prophet of Islam Muhammad. Hart asserted that Muhammad was "supremely successful" in both the religious and secular realms. He also believed that Muhammad's role in the development of Islam was far more influential than Jesus' collaboration in the development of Christianity. He attributes the development of Christianity to St. Paul, who played a pivotal role in its dissemination."

The 1992 revisions included the demotion of figures associated with Communism, such as Vladimir Lenin and Mao Zedong, and the introduction of Mikhail Gorbachev. Hart took sides in the Shakespearean authorship issue and substituted Edward de Vere, 17th Earl of Oxford for William Shakespeare. Hart also substituted Niels Bohr and Henri Becquerel with Ernest Rutherford, thus correcting an error in the first edition. Henry Ford was also promoted from the "Honorary Mentions" list, replacing Pablo Picasso. Finally, some of the rankings were re-ordered, although no one listed in the top ten changed position.

Joel F. Salatin (born 1957) is an American farmer, lecturer, and author whose books include Folks, This Ain't Normal, You Can Farm, and Salad Bar Beef.

Salatin raises livestock using holistic methods of animal husbandry, free of potentially harmful chemicals, on his Polyface Farm in Swoope, Virginia, in the Shenandoah Valley. Meat from the farm is sold by direct-marketing to consumers and restaurants.

In high school, Salatin began his own business selling rabbits, eggs, butter and chicken from his family farm at the Staunton Curb Market. He then attended Bob Jones University where he majored in English and was a student leader. He graduated in 1979. Salatin married his childhood sweetheart in 1980 and became a feature writer at the Staunton, Virginia newspaper, The News Leader, where he had worked earlier typing obituaries and police reports.

Tired of "having his stories spiked," he decided to try farming full-time after first getting involved in a walnut-buying station run by two high school boys. Salatin's grandfather had been an avid gardener and beekeeper and a follower of J. I. Rodale, the founder of regenerative organic gardening. Salatin's father worked as an accountant and his mother taught high school physical education. Salatin's parents had bought the land that became Polyface in 1961 after losing a farm in Venezuela to political turmoil. They had raised cattle using organic methods, but could not make a living at farming alone.
