Cuchillas Del Toa
Cuchillas del Toa () is a Biosphere Reserve in Cuba. It is located in the eastern part of the country, mostly in the Guantánamo Province and reaching to the north into the Holguín Province. Most of the reserve is established in the drainage area of the Toa River, which flows for to the Atlantic Ocean in Baracoa. Overview The reserve extends along , of which to the marine area. Cuchillas del Toa is considered as one of the principal centers of biodiversity and endemism in Cuba and the insular Caribbean with pine forests, cloud forests and xeric scrub to complex coastal vegetation with mangroves and coral reefs. The karstic system of the great cave of Moa Head lands is one of the five natural monuments in the country and one of the great cave systems in eastern Cuba. With high biodiversity in flora and fauna, there are 928 endemic species reported, including primitive species belonging to the genera ''Podocarpus'' and '' Dracaena''. Cuchillas del Toa is home to the highly endan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cuba
Cuba, officially the Republic of Cuba, is an island country, comprising the island of Cuba (largest island), Isla de la Juventud, and List of islands of Cuba, 4,195 islands, islets and cays surrounding the main island. It is located where the northern Caribbean Sea, Gulf of Mexico, and Atlantic Ocean meet.

Cuban Ivory-billed Woodpecker
The Cuban ivory-billed woodpecker () (''Campephilus principalis bairdii'') is a subspecies of the ivory-billed woodpecker native to Cuba. Originally classified as a separate species, recent research has indicated that ''C. p. bairdii'' may, in fact, be sufficiently distinct from the nominate subspecies to once again be regarded as a species in its own right. There have been no confirmed sightings of the Cuban ivory-billed woodpecker since 1987. It is believed to have gone extinct around 1990, but it is currently evaluated by the IUCN as critically endangered, as the survival of small populations is considered a remote possibility and due to unconfirmed reports. However, much like its mainland counterpart, these sightings and reports are widely disputed and polemic. Taxonomy and appearance ''C. p. bairdii'' was originally designated as a separate species (''C. bairdii'') by John Cassin, based on suggestions by Spencer Fullerton Baird. Cassin described it as: Much resembling '' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lacandon Jungle
The Lacandon Jungle ( Spanish: ''Selva Lacandona'') is an area of rainforest which stretches from Chiapas, Mexico, into Guatemala. The heart of this rainforest is located in the Montes Azules Biosphere Reserve in Chiapas near the border with Guatemala in the Montañas del Oriente region of the state. Although much of the jungle outside the reserve has been cleared, the Lacandon is still one of the largest montane rainforests in Mexico. It contains 1,500 tree species, 33% of all Mexican bird species, 25% of all Mexican animal species, 56% of all Mexican diurnal butterflies and 16% of all Mexico's fish species. The Lacandon in Chiapas is also home to a number of important Mayan archaeological sites including Palenque, Yaxchilan and Bonampak, with numerous smaller sites which remain partially or fully unexcavated. This rainforest, especially the area inside the Biosphere Reserve, is a source of political tension, pitting the EZLN or Zapatistas and their indigenous allies who wa ...

Maroon (people)
Maroons are descendants of African diaspora in the Americas, Africans in the Americas and islands of the Indian Ocean who escaped from slavery, through flight or manumission, and formed their own settlements. They often mixed with Indigenous peoples of the Americas, Indigenous peoples, eventually ethnogenesis, evolving into separate creole cultures such as the Garifuna and the Mascogos. Etymology ''Maroon'' entered English around the 1590s, from the French adjective , meaning 'feral' or 'fugitive', itself possibly from the American Spanish word , meaning 'wild, unruly' or 'runaway slave'. In the early 1570s, Sir Francis Drake's Francis Drake's expedition of 1572–1573, raids on the Spanish in Panama were aided by "''Symerons''", a likely misspelling of '. The linguist Leo Spitzer, writing in the journal ''Language (journal), Language'', says, "If there is a connection between Eng. ''maroon'', Fr. ', and Sp. ', Spain (or Spanish America) probably gave the word directly to E ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Atlantic Slave Trade
The Atlantic slave trade or transatlantic slave trade involved the transportation by slave traders of Slavery in Africa, enslaved African people to the Americas. European slave ships regularly used the triangular trade route and its Middle Passage. Europeans established a coastal slave trade in the 15th century and trade to the Americas began in the 16th century, lasting through the 19th century. The vast majority of those who were transported in the transatlantic slave trade were from Central Africa and West Africa and had been sold by West African slave traders to European slave traders, while others had been captured directly by the slave traders in coastal raids. European slave traders gathered and imprisoned the enslaved at slave fort, forts on the African coast and then brought them to the Americas. Some Portuguese and Europeans participated in slave raids. As the National Museums Liverpool explains: "European traders captured some Africans in raids along the coast, but bou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cobalt
Cobalt is a chemical element; it has Symbol (chemistry), symbol Co and atomic number 27. As with nickel, cobalt is found in the Earth's crust only in a chemically combined form, save for small deposits found in alloys of natural meteoric iron. The free element, produced by reductive smelting, is a hard, lustrous, somewhat brittle, gray metal. Cobalt-based blue pigments (cobalt blue) have been used since antiquity for jewelry and paints, and to impart a distinctive blue tint to glass. The color was long thought to be due to the metal bismuth. Miners had long used the name ''kobold ore'' (German language, German for ''goblin ore'') for some of the blue pigment-producing minerals. They were so named because they were poor in known metals and gave off poisonous arsenic-containing fumes when smelted. In 1735, such ores were found to be reducible to a new metal (the first discovered since ancient times), which was ultimately named for the ''kobold''. Today, some cobalt is produced sp ...

Iron
Iron is a chemical element; it has symbol Fe () and atomic number 26. It is a metal that belongs to the first transition series and group 8 of the periodic table. It is, by mass, the most common element on Earth, forming much of Earth's outer and inner core. It is the fourth most abundant element in the Earth's crust, being mainly deposited by meteorites in its metallic state. Extracting usable metal from iron ores requires kilns or furnaces capable of reaching , about 500 °C (900 °F) higher than that required to smelt copper. Humans started to master that process in Eurasia during the 2nd millennium BC and the use of iron tools and weapons began to displace copper alloys – in some regions, only around 1200 BC. That event is considered the transition from the Bronze Age to the Iron Age. In the modern world, iron alloys, such as steel, stainless steel, cast iron and special steels, are by far the most common industrial metals, due to their mechan ...

Chromium
Chromium is a chemical element; it has Symbol (chemistry), symbol Cr and atomic number 24. It is the first element in Group 6 element, group 6. It is a steely-grey, Luster (mineralogy), lustrous, hard, and brittle transition metal. Chromium is valued for its high corrosion resistance and hardness. A major development in steel production was the discovery that steel could be made highly resistant to corrosion and discoloration by adding metallic chromium to form stainless steel. Stainless steel and chrome plating (electroplating with chromium) together comprise 85% of the commercial use. Chromium is also greatly valued as a metal that is able to be highly polishing, polished while resisting tarnishing. Polished chromium reflects almost 70% of the visible spectrum, and almost 90% of infrared, infrared light. The name of the element is derived from the Ancient Greek, Greek word χρῶμα, ''chrōma'', meaning color, because many chromium compounds are intensely colored. Indust ...

Nickel
Nickel is a chemical element; it has symbol Ni and atomic number 28. It is a silvery-white lustrous metal with a slight golden tinge. Nickel is a hard and ductile transition metal. Pure nickel is chemically reactive, but large pieces are slow to react with air under standard conditions because a passivation layer of nickel oxide forms on the surface that prevents further corrosion. Even so, pure native nickel is found in Earth's crust only in tiny amounts, usually in ultramafic rocks, and in the interiors of larger nickel–iron meteorites that were not exposed to oxygen when outside Earth's atmosphere. Meteoric nickel is found in combination with iron, a reflection of the origin of those elements as major end products of supernova nucleosynthesis. An iron–nickel mixture is thought to compose Earth's outer and inner cores. Use of nickel (as natural meteoric nickel–iron alloy) has been traced as far back as 3500 BCE. Nickel was first isolated and classifie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ecotourism
Ecotourism is a form of nature-oriented tourism intended to contribute to the Ecological conservation, conservation of the natural environment, generally defined as being minimally impactful, and including providing both contributions to conservation and environmental education. The definition sometimes also includes being financially beneficial to the host community or making conservation financially possible. There are a range of different definitions, and the correct definition of the term was an active subject of debate as of 2009. The term is also used more widely by many organizations offering nature tourism, which do not focus on being beneficial to the environment. Since the 1980s, ecotourism has been considered an important endeavor by environmentalists for conservation reasons. Organizations focusing on ecotourism often make direct or indirect contributions to conservation or employ practices or technology that reduce impacts on the environment. However (according to Bu ...

Cacao Bean
The cocoa bean, also known as cocoa () or cacao (), is the dried and fully fermented seed of ''Theobroma cacao'', the cacao tree, from which cocoa solids (a mixture of nonfat substances) and cocoa butter (the fat) can be extracted. Cacao trees are native to the Amazon rainforest. They are the basis of chocolate and Mesoamerican foods including tejate, an indigenous Mexican drink. The cacao tree was first domesticated at least 5,300 years ago by the Mayo-Chinchipe culture in South America before it was introduced in Mesoamerica. Cacao was consumed by pre-Hispanic cultures in spiritual ceremonies, and its beans were a common currency in Mesoamerica. The cacao tree grows in a limited geographical zone; today, West Africa produces nearly 81% of the world's crop. The three main varieties of cocoa plants are Forastero, Criollo, and Trinitario, with Forastero being the most widely used. In 2024, global cocoa bean production reached 5.8 million tonnes, with Ivory Coast leading at ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coconut
The coconut tree (''Cocos nucifera'') is a member of the palm tree family (biology), family (Arecaceae) and the only living species of the genus ''Cocos''. The term "coconut" (or the archaic "cocoanut") can refer to the whole coconut palm, the seed, or the fruit, which botanically is a drupe, not a Nut (fruit), nut. Originally native to Central Indo-Pacific, they are now ubiquitous in coastal tropical regions and are a cultural icon of the tropics. The coconut tree provides food, fuel, cosmetics, folk medicine and building materials, among many other uses. The inner flesh of the mature seed, as well as the coconut milk extracted from it, forms a regular part of the diets of many people in the tropics and subtropics. Coconuts are distinct from other fruits because their endosperm contains a large quantity of an almost clear liquid, called "coconut water" or "coconut juice". Mature, ripe coconuts can be used as edible seeds, or processed for Coconut oil, oil and Coconut milk, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
