The United Mexican States (Spanish:  Estados Unidos Mexicanos (help·info)), commonly known as Mexico (pronounced /ˈmɛksɨkoʊ/; Spanish: México, IPA: [ˈmexiko] ( listen)), is a federal constitutional republic in North America. It is bordered on the north by the United States; on the south and west by the Pacific Ocean; on the southeast by Guatemala, Belize, and the Caribbean Sea; and on the east by the Gulf of Mexico. Covering almost two million square kilometres (over 760,000 sq mi), Mexico is the fifth largest country in the Americas by total area and the thirteenth largest independent nation in the world. With an estimated population of over 112 million, it is the eleventh most populous country and the most populous Spanish-speaking country. Mexico is a federation comprising thirty-one states and a Federal District, the capital city.

In Pre-Columbian Mesoamerica many cultures matured into advanced civilizations such as the Olmec, the Toltec, the Teotihuacan, the Zapotec, the Maya and the Aztec before the first contact with Europeans. In 1521, Spain conquered and colonized the territory from its base in México-Tenochtitlan, which was administered as the Viceroyalty of New Spain. This territory would eventually become Mexico as the colony's independence was recognized in 1821. The post-independence period was characterized by economic instability, the Mexican-American War and territorial cession to the United States, a civil war, two empires and a domestic dictatorship. The latter led to the Mexican Revolution in 1910, which culminated with the promulgation of the 1917 Constitution and the emergence of the country's current political system. Elections held in July 2000 marked the first time that an opposition party won the presidency from the Institutional Revolutionary Party.

Mexico has one of the world's largest economies, and is considered both a regional power and middle power. In addition, Mexico was the first Latin American member of the Organisation for Economic Co-operation and Development OECD (since 1994), and a firmly established upper-middle income country. Mexico is considered a newly industrialized country and an emerging power. It has the thirteenth largest nominal GDP and the eleventh largest by purchasing power parity. The economy is strongly linked to those of its North American Free Trade Agreement (NAFTA) partners, especially the United States. Mexico ranks fifth in the world and first in the Americas by number of UNESCO World Heritage Sites with 31, and in 2007 was the tenth most visited country in the world with 21.4 million international arrivals per year.

Ancient cultures

The earliest human remains in Mexico are chips of stone tools found near campfire remains in the Valley of Mexico and radiocarbon-dated to ca. 21,000 BCE. Around 9,000 years ago, ancient indigenous peoples domesticated corn and initiated an agricultural revolution, leading to the formation of many complex civilizations. Between 1,800 and 300 BCE, many matured into advanced pre-Columbian Mesoamerican civilizations such as: the Olmec, Izapa, Teotihuacan, Maya, Zapotec, Mixtec, Huastec, Purepecha, Totonac, Toltec and Aztec: Mexica, which flourished for nearly 4,000 years before the first contact with Europeans.

These civilizations are credited with many inventions and advancements in fields such as architecture (pyramid-temples), mathematics, astronomy, medicine and theology. The Aztecs were noted for practicing human sacrifice on a large scale. At its peak, Teotihuacan, containing some of the largest pyramidal structures built in the pre-Columbian Americas, had a population of more than 150,000 people. Estimates of the population before the Spanish conquest range from 6 million to 25 million.

At the time of Spanish contact, Teotihuacan was no longer occupied, although the site was well-known; the population of the Aztec Empire and its immediate predecessors had become centered on Lake Texcoco, also in the Valley of Mexico, where the island city of Tenochtitlan was founded in 1325.

New Spain

In the early 16th century, from the landing of Hernán Cortés, the Aztec civilization was invaded and conquered by the Spaniards. Unintentionally introduced by Spanish conquerors, smallpox ravaged Mesoamerica in the 1520s, killing millions of Aztecs, including the emperor, and was credited with the victory of Hernán Cortés over the Aztec empire. The territory became part of the Spanish Empire under the name of New Spain. Mexico City was systematically rebuilt by Cortés following the Fall of Tenochtitlan in 1521. Much of the identity, traditions and architecture of Mexico were created during the colonial period.

Independence

On September 16, 1810, independence from Spain was declared by priest Miguel Hidalgo y Costilla, in the small town of Dolores, Guanajuato. The first insurgent group was formed by Hidalgo, the Spanish viceregal army captain Ignacio Allende, the militia captain Juan Aldama and "La Corregidora" Josefa Ortiz de Domínguez. Hidalgo and some of his soldiers were captured and executed by firing squad in Chihuahua, on July 31, 1811. Following his death, the leadership was assumed by priest José María Morelos, who occupied key southern cities.

In 1813 the Congress of Chilpancingo was convened and, on November 6, signed the "Solemn Act of the Declaration of Independence of Northern America". Morelos was captured and executed on December 22, 1815. In subsequent years, the insurgency was near collapse, but in 1820 Viceroy Juan Ruiz de Apodaca sent an army under the criollo general Agustín de Iturbide against the troops of Vicente Guerrero. Instead, Iturbide approached Guerrero to join forces, and in 1821 representatives of the Spanish Crown and Iturbide signed the "Treaty of Córdoba" and the "Declaration of Independence of the Mexican Empire", which recognized the independence of Mexico under the terms of the "Plan of Iguala".

Agustín de Iturbide immediately proclaimed himself emperor of the First Mexican Empire. A revolt against him in 1823 established the United Mexican States. In 1824, a Republican Constitution was drafted and Guadalupe Victoria became the first president of the newly born country. The first decades of the post-independence period were marked by economic instability, which led to the Pastry War in 1836, and a constant strife between liberales, supporters of a federal form of government, and conservadores, proposals of a hierarchical form of government.

General Antonio López de Santa Anna, a centralist and two-time dictator, approved the Siete Leyes in 1836, a radical amendment that institutionalized the centralized form of government. When he suspended the 1824 Constitution, civil war spread across the country, and three new governments declared independence: the Republic of Texas, the Republic of the Rio Grande and the Republic of Yucatán.

Texas successfully achieved independence and was annexed by the United States. A border dispute led to the Mexican-American War, which began in 1846 and lasted for two years; the War was settled via the Treaty of Guadalupe Hidalgo, which forced Mexico to give up over half of its land to the U.S., including Alta California, New Mexico, and the disputed parts of Texas. A much smaller transfer of territory in what is today southern Arizona and southwestern New Mexico — the Gadsden Purchase — occurred in 1854. The Caste War of Yucatán, the Mayan uprising that began in 1847, was one of the most successful modern Native American revolts. Maya rebels, or Cruzob, maintained relatively independent enclaves until the 1930s.

Dissatisfaction with Santa Anna's return to power led to the liberal "Plan of Ayutla", initiating an era known as La Reforma, after which a new Constitution was drafted in 1857 that established a secular state, federalism as the form of government, and several freedoms. As the conservadores refused to recognize it, the Reform War began in 1858, during which both groups had their own governments. The war ended in 1861 with victory by the Liberals, led by Amerindian President Benito Juárez. In the 1860s Mexico underwent a military occupation by France, which established the Second Mexican Empire under the rule of Habsburg Archduke Ferdinand Maximilian of Austria with support from the Roman Catholic clergy and the conservadores, who later switched sides and joined the liberales. Maximilian surrendered, was tried on June 14 and was executed on June 19, 1867.

Porfirio Díaz, a republican general during the French intervention, ruled Mexico from 1876–1880 and then from 1884–1911 in five consecutive reelections, period known as the Porfiriato, characterized by remarkable economic achievements, investments in the arts and sciences, but also of economic inequality and political repression.

20th century to present

A likely electoral fraud that led to Diaz's fifth reelection sparked the 1910 Mexican Revolution, initially led by Francisco I. Madero.

Díaz resigned in 1911 and Madero was elected president but overthrown and murdered in a coup d'état two years later directed by conservative general Victoriano Huerta. That event re-ignited the civil war, involving figures such as Francisco Villa and Emiliano Zapata, who formed their own forces. A third force, the constitutional army led by Venustiano Carranza, managed to bring an end to the war, and radically amended the 1857 Constitution to include many of the social premises and demands of the revolutionaries into what was eventually called the 1917 Constitution. It is estimated that the war killed 900,000 of the 1910 population of 15 million.

Assassinated in 1920, Carranza was succeeded by another revolutionary hero, Álvaro Obregón, who in turn was succeeded by Plutarco Elías Calles. Obregón was reelected in 1928 but assassinated before he could assume power. In 1929, Calles founded the National Revolutionary Party (PNR), later renamed the Institutional Revolutionary Party (PRI), and started a period known as the Maximato, which ended with the election of Lázaro Cárdenas, who implemented many economic and social reforms, and most significantly expropriated the oil industry into Pemex on March 18, 1938, but sparked a diplomatic crisis with the countries whose citizens had lost businesses by Cárdenas' radical measure.

Between 1940 and 1980, Mexico experienced a substantial economic growth that some historians call the "Mexican miracle". Although the economy continued to flourish, social inequality remained a factor of discontent. Moreover, the PRI rule became increasingly authoritarian and at times oppressive (see the 1968 Tlatelolco massacre, which claimed the life of around 30–800 protesters).

Electoral reforms and high oil prices followed the administration of Luis Echeverría, mismanagement of these revenues led to inflation and exacerbated the 1982 Crisis. That year, oil prices plunged, interest rates soared, and the government defaulted on its debt. President Miguel de la Madrid resorted to currency devaluations which in turn sparked inflation.

In the 1980s the first cracks emerged in PRI's monopolistic position. In Baja California, Ernesto Ruffo Appel was elected as governor. In 1988, electoral fraud prevented leftist candidate Cuauhtémoc Cárdenas from winning the national presidential elections, giving Carlos Salinas de Gortari the Presidency and leading to massive protests in Mexico City.

Salinas embarked on a program of neoliberal reforms which fixed the exchange rate, controlled inflation and culminated with the signing of the North American Free Trade Agreement (NAFTA), which came into effect on January 1, 1994. The same day, the Zapatista Army of National Liberation (EZLN) started a two-week-long armed rebellion against the federal government, and has continued as a non-violent opposition movement against neoliberalism and globalization.

In December 1994, a month after Salinas was succeeded by Ernesto Zedillo, the Mexican economy collapsed, with a rapid rescue packaged authorized by U.S. President Bill Clinton and major macroeconomic reforms started by president Zedillo, the economy rapidly recovered and growth peaked at almost 7% by the end of 1999.

In 2000, after 71 years, the PRI lost a presidential election to Vicente Fox of the opposition National Action Party (PAN). In the 2006 presidential elections, Felipe Calderón from the PAN was declared the winner, with a very narrow margin over leftist politician Andrés Manuel López Obrador of the Party of the Democratic Revolution (PRD). López Obrador, however, contested the election and pledged to create an "alternative government".

Mexican culture reflects the complexity of the country's history through the blending of indigenous cultures and the culture of Spain, imparted during Spain's 300-year colonization of Mexico. Exogenous cultural elements mainly from the United States have been incorporated into Mexican culture.

The Porfirian era (el Porfiriato), in the last quarter of the 19th century and the first decade of the 20th century, was marked by economic progress and peace. After four decades of civil unrest and war, Mexico saw the development of philosophy and the arts, promoted by President Díaz himself. Since that time, as accentuated during the Mexican Revolution, cultural identity has had its foundation in the mestizaje, of which the indigenous (i.e. Amerindian) element is the core. In light of the various ethnicities that formed the Mexican people, José Vasconcelos in his publication La Raza Cósmica (The Cosmic Race) (1925) defined Mexico to be the melting pot of all races (thus extending the definition of the mestizo) not only biologically but culturally as well. This exalting of mestizaje was a revolutionary idea that sharply contrasted with the idea of a superior pure race prevalent in Europe at the time.

Literature

The literature of Mexico has its antecedents in the literatures of the indigenous settlements of Mesoamerica. The most well known prehispanic poet is Nezahualcoyotl. Modern Mexican literature was influenced by the concepts of the Spanish colonialization of Mesoamerica. Outstanding colonial writers and poets include Juan Ruiz de Alarcón and Juana Inés de la Cruz.

In light of the various ethnicities that formed the Mexican people, José Vasconcelos in his publication La Raza Cósmica (The Cosmic Race) (1925) defined Mexico to be the melting pot of all races, biologically as well as culturally.

Other writers include Alfonso Reyes, José Joaquín Fernández de Lizardi, Ignacio Manuel Altamirano, Carlos Fuentes, Octavio Paz (Nobel Laureate), Renato Leduc, Carlos Monsiváis, Elena Poniatowska, Mariano Azuela ("Los de abajo") and Juan Rulfo ("Pedro Páramo"). Bruno Traven wrote "Canasta de cuentos mexicanos", "El tesoro de la Sierra Madre."

Visual arts

Post-revolutionary art in Mexico had its expression in the works of renowned artists such as Frida Kahlo, Diego Rivera, José Clemente Orozco, Rufino Tamayo, Federico Cantú Garza, David Alfaro Siqueiros and Juan O'Gorman. Diego Rivera, the most well-known figure of Mexican muralism, painted the Man at the Crossroads at the Rockefeller Center in New York City, a huge mural that was destroyed the next year due to the inclusion of a portrait of Russian communist leader Lenin. Some of Rivera's murals are displayed at the Mexican National Palace and the Palace of Fine Arts.

Mesoamerican architecture is mostly noted for its pyramids which are the largest such structures outside of Ancient Egypt. Spanish Colonial architecture is marked by the contrast between the simple, solid construction demanded by the new environment and the Baroque ornamentation exported from Spain. Mexico, as the center of New Spain has some of the most renowned buildings built in this style.

Cinema and media

Mexican films from the Golden Age in the 1940s and 1950s are the greatest examples of Latin American cinema, with a huge industry comparable to the Hollywood of those years. Mexican films were exported and exhibited in all of Latin America and Europe. Maria Candelaria (1944) by Emilio Fernández, was one of the first films awarded a Palme d'Or at the Cannes Film Festival in 1946, the first time the event was held after World War II. The famous Spanish-born director Luis Buñuel realized in Mexico, between 1947 to 1965 some of him master pieces like Los Olvidados (1949), Viridiana (1961) and El angel exterminador (1963). Famous actors and actresses from this period include María Félix, Pedro Infante, Dolores del Río, Jorge Negrete and the comedian Cantinflas.

More recently, films such as Como agua para chocolate (1992), Cronos (1993), Amores perros (2000), Y tu mamá también (2001), El crimen del Padre Amaro (The Crime of Father Amaro) (2002), Pan's Labyrinth (2006) and Babel (2006) have been successful in creating universal stories about contemporary subjects, and were internationally recognised, as in the prestigious Cannes Film Festival. Mexican directors Alejandro González Iñárritu (Amores perros, Babel), Alfonso Cuarón (Children of Men, Harry Potter and the Prisoner of Azkaban), Guillermo del Toro, Carlos Carrera (The Crime of Father Amaro), and screenwriter Guillermo Arriaga are some of the most known present-day film makers.

Two of the major television networks based in Mexico are Televisa and TV Azteca. Televisa is also the largest producer of Spanish-language content in the world and also the world's largest Spanish-language media network. Grupo Multimedios is another media conglomerate with Spanish-language broadcasting in Mexico, Spain, and the United States. Soap operas (telenovelas) are translated to many languages and seen all over the world with renowned names like Verónica Castro, Lucía Méndez, Lucero, and Thalía.

Music

Mexican society enjoys a vast array of music genres, showing the diversity of Mexican culture. Traditional music includes Mariachi, Banda, Norteño, Ranchera and Corridos; on an every-day basis most Mexicans listen to contemporary music such as pop, rock, etc. in both English and Spanish. Mexico has the largest media industry in Latin America, producing Mexican artists who are famous in Central and South America and parts of Europe, especially Spain. Some well-known Mexican singers are Thalía, Luis Miguel, Alejandro Fernández, Julieta Venegas and Paulina Rubio. Mexican singers of traditional music are: Lila Downs, Susana Harp, Jaramar, GEO Meneses and Alejandra Robles. Popular groups are Café Tacuba, Molotov and Maná, among others. Since the early 2000s Mexican rock has seen widespread growth both domesticly and internationally.

According to the Sistema Nacional de Fomento Musical, there are between 120 and 140 youth orchestras affiliated to this federal agency from all federal states. Some states, through their state agencies in charge of culture and the arts—Ministry or Secretary or Institute or Council of Culture, in some cases Secretary of Education or the State University—sponsor the activities of a professional Symphony Orchestra or Philharmonic Orchestra so all citizens can have access to this artistic expression from the field of classical music. Mexico City is the most intense hub of this activity hosting 12 professional orchestras sponsored by different agencies such as the National Intitute of Fine Arts, the Secretary of Culture of the Federal District, The National University, the National Polytechnic Institute, a Delegación Política (Coyoacán) and very few are a kind of private ventures.

Cuisine

Mexican cuisine is known for its intense and varied flavors, colorful decoration, and variety of spices. Most of today's Mexican food is based on pre-Columbian traditions, including the Aztecs and Maya, combined with culinary trends introduced by Spanish colonists.

The conquistadores eventually combined their imported diet of rice, beef, pork, chicken, wine, garlic and onions with the native pre-Columbian food, including maize, tomato, vanilla, avocado, guava, papaya, pineapple, chili pepper, beans, squash, sweet potato, peanut, and turkey.

Mexican food varies by region, because of local climate and geography and ethnic differences among the indigenous inhabitants and because these different populations were influenced by the Spaniards in varying degrees. The north of Mexico is known for its beef, goat and ostrich production and meat dishes, in particular the well-known Arrachera cut.

Central Mexico's cuisine is largely made up of influences from the rest of the country, but also has its authentics, such as barbacoa, pozole, menudo, tamales, and carnitas.

Southeastern Mexico, on the other hand, is known for its spicy vegetable and chicken-based dishes. The cuisine of Southeastern Mexico also has quite a bit of Caribbean influence, given its geographical location. Veal is common in the Yucatan. Seafood is commonly prepared in the states that border the Pacific Ocean or the Gulf of Mexico, the latter having a famous reputation for its fish dishes, in particular à la veracruzana.

In modern times, other cuisines of the world have become very popular in Mexico, thus adopting a Mexican fusion. For example, sushi in Mexico is often made with a variety of sauces based on mango or tamarind, and very often served with serrano-chili-blended soy sauce, or complemented with vinegar, habanero and chipotle peppers

The most internationally recognized dishes include chocolate, tacos, quesadillas, enchiladas, burritos, tamales and mole among others. Regional dishes include mole poblano, chiles en nogada and chalupas from Puebla; cabrito and machaca from Monterrey, cochinita pibil from Yucatán, Tlayudas from Oaxaca, as well as barbacoa, chilaquiles, milanesas, and many others.

Sports

Mexico City hosted the XIX Olympic Games in 1968, making it the first Latin American city to do so. The country has also hosted the FIFA World Cup twice, in 1970 and 1986.

Mexico's most popular sport is association football (soccer). It is commonly believed that Football was introduced in Mexico by Cornish miners at the end of the 19th century. By 1902 a five-team league had emerged with a strong British influence. Mexico's top clubs are Guadalajara with 11 championships, América with 10 and Toluca with 9. Antonio Carbajal was the first player to appear in five World Cups, and Hugo Sánchez was named best CONCACAF player of the 20th century by IFFHS.

Baseball has traditionally been more popular than soccer in some regions. The Mexican professional league is named the Liga Mexicana de Beisbol. While usually not as strong as the United States, the Caribbean countries and Japan, Mexico has nonetheless achieved several international baseball titles. Mexico has had several players signed by Major League teams, the most famous of them being Dodgers pitcher Fernando Valenzuela.

Bullfighting is a popular sport in the country, and almost all large cities have bullrings. Plaza México in Mexico City, is the largest bullring in the world, which seats 55,000 people. Professional wrestling (or Lucha libre in Spanish) is a major crowd draw with national promotions such as AAA, LLL, CMLL and others.

Mexico is an international power in professional boxing (at the amateur level, several Olympic boxing medals have also been won by Mexico). Vicente Saldivar, Rubén Olivares, Salvador Sánchez, Julio César Chávez, Ricardo Lopez and Erik Morales are but a few Mexican fighters who have been ranked among the best of all time.

Notable Mexican athletes include golfer Lorena Ochoa, who was ranked first in the LPGA world rankings prior to her retirement, Ana Guevara, former world champion of the 400 metres (1,300 ft) and Olympic subchampion in Athens 2004, and Fernando Platas, a numerous Olympic medal winning diver.

Mexico is located between latitudes 14° and 33°N, and longitudes 86° and 119°W in the southern portion of North America. Almost all of Mexico lies in the North American Plate, with small parts of the Baja California peninsula on the Pacific and Cocos Plates. Geophysically, some geographers include the territory east of the Isthmus of Tehuantepec (around 12% of the total) within Central America. Geopolitically, however, Mexico is entirely considered part of North America, along with Canada and the United States.

Mexico's total area is 1,972,550 km (761,606 sq mi), making it the world's 14th largest country by total area, and includes approximately 6,000 km (2,317 sq mi) of islands in the Pacific Ocean (including the remote Guadalupe Island and the Revillagigedo Islands), Gulf of Mexico, Caribbean, and Gulf of California. From its farthest land points, Mexico is a little over 2,000 mi (3,219 km) in length.

On its north, Mexico shares a 3,141 km (1,952 mi) border with the United States. The meandering Río Bravo del Norte (known as the Rio Grande in the United States) defines the border from Ciudad Juárez east to the Gulf of Mexico. A series of natural and artificial markers delineate the United States-Mexican border west from Ciudad Juárez to the Pacific Ocean. On its south, Mexico shares an 871 km (541 mi) border with Guatemala and a 251 km (156 mi) border with Belize.

Mexico is crossed from north to south by two mountain ranges known as Sierra Madre Oriental and Sierra Madre Occidental, which are the extension of the Rocky Mountains from northern North America. From east to west at the center, the country is crossed by the Trans-Mexican Volcanic Belt also known as the Sierra Nevada. A fourth mountain range, the Sierra Madre del Sur, runs from Michoacán to Oaxaca.

As such, the majority of the Mexican central and northern territories are located at high altitudes, and the highest elevations are found at the Trans-Mexican Volcanic Belt: Pico de Orizaba (5,700 m, 18,701 ft), Popocatepetl (5,462 m, 17,920 ft) and Iztaccihuatl (5,286 m, 17,343 ft) and the Nevado de Toluca (4,577 m, 15,016 ft). Three major urban agglomerations are located in the valleys between these four elevations: Toluca, Greater Mexico City and Puebla.

Climate

The Tropic of Cancer effectively divides the country into temperate and tropical zones. Land north of the twenty-fourth parallel experiences cooler temperatures during the winter months. South of the twenty-fourth parallel, temperatures are fairly constant year round and vary solely as a function of elevation. This gives Mexico one of the world's most diverse weather systems.

Areas south of the twenty-fourth parallel with elevations up to 1,000 m (3,281 ft) (the southern parts of both coastal plains as well as the Yucatán Peninsula), have a yearly median temperature between 24 to 28 °C (75.2 to 82.4 °F). Temperatures here remain high throughout the year, with only a 5 °C (9 °F) difference between winter and summer median temperatures. Both Mexican coasts, except for the south coast of the Bay of Campeche and northern Baja, are also vulnerable to serious hurricanes during the summer and fall. Although low-lying areas north of the twentieth-fourth parallel are hot and humid during the summer, they generally have lower yearly temperature averages (from 20 to 24 °C or 68 to 75.2 °F) because of more moderate conditions during the winter.

Many large cities in Mexico are located in the Valley of Mexico or in adjacent valleys with altitudes generally above 2,000 m (6,562 ft). This gives them a year-round temperate climate with yearly temperature averages (from 16 to 18 °C or 60.8 to 64.4 °F) and cool nighttime temperatures throughout the year.

Many parts of Mexico, particularly the north, have a dry climate with sporadic rainfall while parts of the tropical lowlands in the south average more than 2,000 mm (78.7 in) of annual precipitation. For example, many cities in the north like Monterrey, Hermosillo, and Mexicali experience temperatures of 40 °C (104 °F) or more in summer. In the Sonoran Desert temperatures reach 50 °C (122 °F) or more.

Biodiversity

Mexico is one of the 18 megadiverse countries of the world. With over 200,000 different species, Mexico is home of 10–12% of the world's biodiversity. Mexico ranks first in biodiversity in reptiles with 707 known species, second in mammals with 438 species, fourth in amphibians with 290 species, and fourth in flora, with 26,000 different species. Mexico is also considered the second country in the world in ecosystems and fourth in overall species. Approximately 2,500 species are protected by Mexican legislations.

As of 2002, Mexico had the second fastest rate of deforestation in the world, second only to Brazil. The government has taken another initiative in the late 1990s to expand the people's knowledge, interest and use of the country's esteemed biodiversity, through the Comisión Nacional para el Conocimiento y Uso de la Biodiversidad.

In Mexico, 170,000 square kilometres (65,637 sq mi) are considered "Protected Natural Areas." These include 34 reserve biospheres (unaltered ecosystems), 64 national parks, 4 natural monuments (protected in perpetuity for their aesthetic, scientific or historical value), 26 areas of protected flora and fauna, 4 areas for natural resource protection (conservation of soil, hydrological basins and forests) and 17 sanctuaries (zones rich in diverse species).

The discovery of the Americas brought to the rest of the world many widely used food crops and edible plants. Some of Mexico's native culinary ingredients include: chocolate, avocado, tomato, maize, vanilla, guava, chayote, epazote, camote, jícama, nopal, zucchini, tejocote, huitlacoche, sapote, mamey sapote, many varieties of beans, and an even greater variety of chiles, such as the habanero and the jalapeño. Most of these names come from indigenous languages like Nahuatl.
