Some context: Mumtaz Mahal (Urdu: mumtz mHal ), ([mum'ta:z me'hel]; meaning "the Exalted One of the palace"; Arjumand Banu; 27 April 1593 - 17 June 1631) was Empress consort of the Mughal Empire from 19 January 1628 to 17 June 1631 as the chief consort of the Mughal emperor Shah Jahan. The UNESCO World Heritage Site Taj Mahal in Agra, often cited as one of the Wonders of the World, was commissioned to act as her final resting place. Mumtaz Mahal was born Arjumand Banu Begum in Agra to a family of Persian nobility.
Upon his accession to the throne in 1628, Shah Jahan designated Mumtaz as his chief empress with the title of 'Malika-i-Jahan' ("Queen of the World") and 'Malika-uz-Zamani' ("Queen of the Age"). Mumtaz's tenure as empress was brief (spanning a period of only three years due to her untimely death), nonetheless Shah Jahan bestowed her with luxuries that no other empress was given before her. For example, no other empress' residence was as decorated as Khas Mahal (part of Agra Fort), where Mumtaz lived with Shah Jahan. It was decorated with pure gold and precious stones and had rose water fountains of its own. Each wife of the Mughal emperor was given regular monthly allowance for her gastos (housekeeping or travelling expenses). The highest allowance on record is 10 lakh rupees per year given to Mumtaz Mahal under Shah Jahan. Shah Jahan consulted Mumtaz in both private matters and the affairs of the state and she served as his close confidante and trusted adviser. At her intercession, he forgave enemies or commuted death sentences. His trust in her was so great that he gave her the highest honour of the land -- his imperial seal, the Mehr Uzaz, which validated imperial decrees. Mumtaz was portrayed as having no aspirations to political power, in contrast to her aunt, Empress Nur Jahan, the chief consort of Emperor Jahangir, who had wielded considerable influence in the previous reign. A great influence on him, often intervening on behalf of the poor and destitute, she also enjoyed watching elephant and combat fights performed for the court. Mumtaz also patronized a number of poets, scholars and other talented persons. A noted Sanskrit poet, Vansidhara Mishra, was the Empress' favourite. On the recommendation of her principal lady-in-waiting, Sati-un-Nissa, Mumtaz Mahal provided pensions and donations to the daughters of poor scholars, theologians, and pious men. It was quite common for women of noble birth to commission architecture in the Mughal Empire, so Mumtaz devoted some time to a riverside garden in Agra, which is now known as Zahara Bagh. It is the only architectural foundation which can be connected to her patronage.

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.
