IN: The Merchandise Mart (or the Merch Mart, or the Mart) is a commercial building located in the downtown Loop, of Chicago, Illinois, United States. When it opened in 1930, it was the largest building in the world, with 4,000,000 square feet (372,000 m2) of floor space. The art deco landmark is located at the junction of the Chicago River's branches. The building is a leading retailing and wholesale destination, hosting 20,000 visitors and tenants per day as of the late 2000s.

Under Chris Kennedy's leadership of the Mart, it was the largest building in the world to be awarded LEED (Leadership in Energy and Environmental Design) Certification in 2007 from the United States Green Building Council (USGBC). The Mart has long been implementing sustainable practices. The Mart Center began operating a thermal storage facility in 1986, capable of building 2,000,000 pounds (910,000 kg) of ice per night, cooling 71 buildings in the surrounding neighborhood, and saving $200,000 in electricity costs in the first year. In 1990, the Mart Center began using Green Seal-approved green cleaning products and the next year implemented a recycling program, which today includes all forms of paper products, glass, light bulbs, batteries, aluminum and construction materials. In 1996, the Mart Center became one of the first major property owners in downtown Chicago to enter into an agreement with the district cooling system now known as Thermal Chicago, thus contributing to the national effort to reduce the discharge of ozone-damaging CFCs. In 2006, MMPI joined Clean Air Counts, a voluntary initiative to reduce smog forming pollutants and energy consumption in the Chicago area. Part of the campaign strategies included utilizing only low VOC cleaning products, paints and building materials, as well as energy efficient lighting and alternative workplace transportation options. To date, the Mart Center has reduced pollution by 264,018 pounds (119,757 kg), the largest reduction by a commercial building. That same year, the Mart Center recycling program saved over 13,000 trees and recycled nearly 11 million pounds of waste, while water conservation efforts saved 5.5 million US gallons (21,000 m3) of water. More than eight percent of the estimated 10,000 people working at the Mart walk, bike or take public transportation; to encourage greener methods of transportation, the Mart expanded bicycle storage capacity to more than 200. In 2009, MMPI converted all stationery to a one hundred percent post-consumer recycled product. The Mart has nine LEED-certified showrooms, with five others on their way to LEED certification.
QUESTION: What did the recycling program include?
IN: The Principalia or noble class was the ruling and usually educated upper class in the pueblos of the Spanish Philippines, comprising the gobernadorcillo (who had functions similar to a town mayor), and the cabezas de barangay (heads of the barangays) who governed the districts. The distinction or status of being part of the principalia was a hereditary right. However, it could also be acquired, as attested by the royal decree of 20 December 1863 (signed in the name of Queen Isabella II by the Minister of the Colonies, Jose de la Concha). This distinguished upper class was exempted from tribute (tax) to the Spanish crown during the colonial period.

From the beginning of the colonial period in the Philippine, the Spanish government built on the traditional pre-conquest socio-political organization of the barangay and co-opted the traditional indigenous princes and their nobles, thereby ruling indirectly. The barangays in some coastal places in Panay, Manila, Cebu, Jolo, and Butuan, with cosmopolitan cultures and trade relations with other countries in Asia, were already established principalities (Kinadatuan) before the coming of the Spaniards. In other regions, even though the majority of these barangays were not large settlements, yet they had organized societies dominated by the same type of recognized aristocracy and lordships (with birthright claim to allegiance from followers), as those found in more established, richer and more developed principalities. The aristocratic group in these pre-colonial societies was called the datu class. Its members were presumably the descendants of the first settlers on the land or, in the case of later arrivals, of those who were datus at the time of migration or conquest. The duty of the datus was to rule and govern their subjects and followers, and to assist them in their interests and necessities. What the chiefs received from their followers was: to be held by them in great veneration and respect; and they were served in their wars and voyages, and in their tilling, sowing, fishing, and the building of their houses. The natives attended to these duties very promptly, whenever summoned by their chief. They also paid their chief tribute (which they called buwis) in varying quantities, in the crops that they gathered. The descendants of such chiefs, and their relatives, even though they did not inherit the Lordship, were held in the same respect and consideration, and were all regarded as nobles and as persons exempt from the services rendered by the others, or the plebeians (timawas). The same right of nobility and chieftainship was preserved for the women, just as for the men. Some of these principalities and lordships have remained, even until the present, in unHispanicized and mostly Lumad and Muslim parts of the Philippines, in some regions of Mindanao.

Where did the natives attend?
