Some context: Michael Bloomberg was born at St. Elizabeth's Hospital, in the Brighton neighborhood of Boston, on February 14, 1942. Bloomberg's family is Jewish. Bloomberg's father, William Henry Bloomberg (1906-1963), was born in Chelsea, Massachusetts and worked as an accountant for a dairy company. He was the son of Alexander "Elick" Bloomberg, an immigrant from Russia.
During his second term as the mayor of New York City, Bloomberg unveiled PlaNYC: A Greener, Greater New York on April 22, 2007, to fight global warming, protect the environment and prepare for the projected 1 million additional people expected to be living in the city by the year 2030.  Under PlaNYC, in just 6 years New York City reduced citywide greenhouse gas emissions by 19% since 2005 and was on track to achieve a 30% reduction ahead of the PlaNYC 2030 goal. In October 2007 as part of PlaNYC, Bloomberg launched the Million Trees NYC initiative, which aimed to plant and care for one million trees throughout the city in the next decade. In November 2015, New York City planted its one millionth tree, two years ahead of the original 10-year schedule.  In 2008, Bloomberg convened the New York City Panel on Climate Change (NPCC), an effort to prepare the city for climate change. In 2012, Travel + Leisure readers voted New York City the "Dirtiest American City," for having the most extant litter. Bloomberg has been involved in motivating other cities to make changes and has spoken about reducing carbon dioxide emissions, using cleaner and more efficient fuels, using congestion pricing in New York City, and encouraging public transportation.  Bloomberg unveiled the Special Initiative for Rebuilding and Resiliency (SIRR) in June 2013, after the city was affected by Hurricane Sandy in October 2012. The $20-billion initiative laid out extensive plans to protect New York City against future the impacts of climate change. On September 26, 2013, Bloomberg announced that his administration's air pollution reduction efforts had resulted in the best air quality in New York City in more than 50 years. The majority of the air quality improvement was attributed to the phasing out of heavy polluting heating oils through New York's "Clean Heat" program. As a result of the improved air quality, the average life expectancy of New Yorkers had increased three years during Bloomberg's tenure, compared to 1.8 years in the rest of the country.

Some context: Ferdinand Magellan ( or ; Portuguese: Fernao de Magalhaes, IPA: [fir'naw di maga'yajS]; Spanish: Fernando de Magallanes, IPA: [fer'nando de maga'yanes]; c. 1480 - 27 April 1521) was a Portuguese explorer who organised the Spanish expedition to the East Indies from 1519 to 1522, resulting in the first circumnavigation of the Earth, completed by Juan Sebastian Elcano. Born into a Portuguese noble family in around 1480, Magellan became a skilled sailor and naval officer and was eventually selected by King Charles I of Spain to search for a westward route to the Maluku Islands (the "Spice Islands"). Commanding a fleet of five vessels, he headed south through the Atlantic Ocean to Patagonia, passing through the Strait of Magellan into a body of water he named the "peaceful sea" (the modern Pacific Ocean).
On 10 August 1519, the five ships under Magellan's command left Seville and descended the Guadalquivir River to Sanlucar de Barrameda, at the mouth of the river. There they remained more than five weeks. Finally they set sail on 20 September 1519 and left Spain.  King Manuel I ordered a Portuguese naval detachment to pursue Magellan, but the explorer evaded them. After stopping at the Canary Islands, Magellan arrived at Cape Verde, where he set course for Cape St. Augustine in Brazil. On 27 November the expedition crossed the equator; on 6 December the crew sighted South America.  On 13 December anchored near present-day Rio de Janeiro. There the crew was resupplied, but bad conditions caused them to delay. Afterwards, they continued to sail south along South America's east coast, looking for the strait that Magellan believed would lead to the Spice Islands. The fleet reached Rio de la Plata in early February, 1520.  For overwintering, Magellan established a temporary settlement called Puerto San Julian on March 30, 1520. On Easter (April 1 and 2), a mutiny broke out involving three of the five ship captains. Magellan took quick and decisive action. Luis de Mendoza, the captain of Victoria, was killed by a party sent by Magellan, and the ship was recovered. After Concepcion's anchor cable had been secretly cut by his forces, the ship drifted towards the well-armed Trinidad, and Concepcion's captain de Quesada and his inner circle surrendered. Juan de Cartagena, the head of the mutineers on the San Antonio, subsequently gave up. Antonio Pigafetta reported that Gaspar Quesada, the captain of Concepcion, and other mutineers were executed, while Juan de Cartagena, the captain of San Antonio, and a priest named Padre Sanchez de la Reina were marooned on the coast. Most of the men, including Juan Sebastian Elcano, were needed and forgiven. Reportedly those killed were drawn and quartered and impaled on the coast; years later, their bones were found by Sir Francis Drake.
