Avocado
The avocado (''Persea americana'') is a medium-sized, evergreen tree in the laurel family (Lauraceae). It is native to the Americas and was first domesticated by Mesoamerican tribes more than 5,000 years ago. Then as now it was prized for its large and unusually oily fruit. The tree likely originated in the highlands bridging south-central Mexico and Guatemala. Its fruit, sometimes also referred to as an alligator or avocado pear, is botanically a large berry containing a single large seed. Avocado trees are partially self-pollinating, and are often propagated through grafting to maintain consistent fruit output. Avocados are presently cultivated in the tropical and Mediterranean climates of many countries. Mexico is the world's leading producer of avocados as of 2020, supplying nearly 30% of the global harvest in that year. The fruit of domestic varieties have smooth, buttery, golden-green flesh when ripe. Depending on the cultivar, avocados have green, brown, purplish, ...

Avocado Oil
Avocado oil is an Vegetable oil, edible oil extracted from the pulp of avocados, the fruit of ''Persea americana''. It is used as an edible oil both raw and for cooking, where it is noted for its high smoke point. It is also used for lubrication and in cosmetics. Avocado oil has an unusually high smoke point: for unrefined oil and for refined. The exact smoke point depends heavily on the quality of refinement and the way the oil is stored. Uses Avocado oil functions well as a carrier oil for other flavors. It is high in monounsaturated fats and vitamin E, and also enhances the absorption of carotenoids and other nutrients. Following drying of the avocado flesh to remove as much water as possible (the flesh is about 65% water), oil for cosmetics is usually extracted with solvents at elevated temperatures. After extraction, it is usually refined, bleached, and deodorized, resulting in an odorless yellow oil. Edible cold-pressed avocado oil is generally unrefined, like extra virgin ...

Berry (botany)
In botany, a berry is a fleshy fruit without a stone (pit) produced from a single flower containing one ovary. Berries so defined include grapes, currants, and tomatoes, as well as cucumbers, eggplants (aubergines) and bananas, but exclude certain fruits that meet the culinary definition of berries, such as strawberries and raspberries. The berry is the most common type of fleshy fruit in which the entire outer layer of the ovary wall ripens into a potentially edible "pericarp". Berries may be formed from one or more carpels from the same flower (i.e. from a simple or a compound ovary). The seeds are usually embedded in the fleshy interior of the ovary, but there are some non-fleshy exceptions, such as peppers, with air rather than pulp around their seeds. Many berries are edible, but others, such as the fruits of the potato and the deadly nightshade, are poisonous to humans. A plant that bears berries is said to be bacciferous or baccate (a fruit that resembles a ber ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Agriculture In Mexico
''Agriculture in Mexico'' has been an important sector of the country’s economy historically and politically even though it now accounts for a very small percentage of Mexico’s GDP. Mexico is one of the cradles of agriculture with the Mesoamericans developing domesticated plants such as maize, beans, tomatoes, squash, cotton, vanilla, avocados, cacao, various kinds of spices, and more. Domestic turkeys and Muscovy ducks were the only domesticated fowl in the pre-Hispanic period and small dogs were raised for food. There were no large domesticated animals. During the early colonial period, the Spanish introduced more plants and the concept of animal husbandry, principally cattle, horses, donkeys, mules, goats and sheep, and barnyard animals such as chickens and pigs. Farming from the colonial period until the Mexican Revolution was focused on large private properties. After the Revolution, these were broken up and the land redistributed. Since the latter 20th century NAFTA ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plant Propagation
Plant propagation is the process by which new plants grow from a variety of sources: seeds, cuttings, and other plant parts. Plant propagation can also refer to the man-made or natural dispersal of seeds. Propagation typically occurs as a step in the overall cycle of plant growth. For seeds, it happens after ripening and dispersal; for vegetative parts, it happens after detachment or pruning; for asexually-reproducing plants, such as strawberry, it happens as the new plant develops from existing parts. Plant propagation can be divided into four basic types: sexual, asexual (vegetative), layering, and grafting. Countless plants are propagated each day in horticulture and agriculture. The materials commonly used for plant propagation are seeds and cuttings. Sexual propagation Seeds and spores can be used for reproduction (e.g. sowing). Seeds are typically produced from sexual reproduction within a species because genetic recombination has occurred. A plant grown from seeds may ...

Lauraceae
Lauraceae, or the laurels, is a plant family that includes the true laurel and its closest relatives. This family comprises about 2850 known species in about 45 genera worldwide (Christenhusz & Byng 2016 ). They are dicotyledons, and occur mainly in warm temperate and tropical regions, especially Southeast Asia and South America. Many are aromatic evergreen trees or shrubs, but some, such as ''Sassafras'', are deciduous, or include both deciduous and evergreen trees and shrubs, especially in tropical and temperate climates. The genus ''Cassytha'' is unique in the Lauraceae in that its members are parasitic vines. Most laurels are highly-poisonous. Overview The family has a worldwide distribution in tropical and warm climates. The Lauraceae are important components of tropical forests ranging from low-lying to montane. In several forested regions, Lauraceae are among the top five families in terms of the number of species present. The Lauraceae give their name to habitats know ...

Grafting
Grafting or graftage is a horticultural technique whereby tissues of plants are joined so as to continue their growth together. The upper part of the combined plant is called the scion () while the lower part is called the rootstock. The success of this joining requires that the vascular tissues grow together and such joining is called inosculation. The technique is most commonly used in asexual propagation of commercially grown plants for the horticultural and agricultural trades. In most cases, one plant is selected for its roots and this is called the stock or rootstock. The other plant is selected for its stems, leaves, flowers, or fruits and is called the scion or cion. The scion contains the desired genes to be duplicated in future production by the stock/scion plant. In stem grafting, a common grafting method, a shoot of a selected, desired plant cultivar is grafted onto the stock of another type. In another common form called bud grafting, a dormant side bud is gra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Organized Crime In Mexico
Crime is one of the most urgent concerns facing Mexico, as Mexican drug trafficking rings play a major role in the flow of cocaine, methamphetamine, fentanyl, heroin, and marijuana transiting between Latin America and the United States. Drug trafficking has led to corruption, which has had a deleterious effect on Mexico's Federal Representative Republic. Drug trafficking and organized crime have been a major source of violent crime in Mexico. Drug cartels and gangs have also branched out to conduct alternative illegal activities for profit, including sex trafficking in Mexico. Some of the most increasingly violent states in Mexico in 2020 included Guanajuato, Zacatecas, Michoacán, Jalisco, and Querétaro. Some of the world's most violent cities are reportedly within the state of Guanajuato with extortion from criminal groups (such as CSRL and CJNG) now being commonplace. The state of Zacatecas is said to be valuable to multiple organized crime groups (including the Sinaloa Cart ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Deforestation
Deforestation or forest clearance is the removal of a forest or stand of trees from land that is then converted to non-forest use. Deforestation can involve conversion of forest land to farms, ranches, or urban use. The most concentrated deforestation occurs in tropical rainforests. About 31% of Earth's land surface is covered by forests at present. This is one-third less than the forest cover before the expansion of agriculture, a half of that loss occurring in the last century. Between 15 million to 18 million hectares of forest, an area the size of Bangladesh, are destroyed every year. On average 2,400 trees are cut down each minute. The Food and Agriculture Organization of the United Nations defines deforestation as the conversion of forest to other land uses (regardless of whether it is human-induced). "Deforestation" and "forest area net change" are not the same: the latter is the sum of all forest losses (deforestation) and all forest gains (forest expansion) in a gi ...

Externality
In economics, an externality or external cost is an indirect cost or benefit to an uninvolved third party that arises as an effect of another party's (or parties') activity. Externalities can be considered as unpriced goods involved in either consumer or producer market transactions. Air pollution from motor vehicles is one example. The cost of air pollution to society is not paid by either the producers or users of motorized transport to the rest of society. Water pollution from mills and factories is another example. All consumers are all made worse off by pollution but are not compensated by the market for this damage. A positive externality is when an individual's consumption in a market increases the well-being of others, but the individual does not charge the third party for the benefit. The third party is essentially getting a free product. An example of this might be the apartment above a bakery receiving the benefit of enjoyment from smelling fresh pastries every mornin ...

Effects Of Climate Change On Agriculture
The effects of climate change on agriculture can result in lower crop yields and nutritional quality due to drought, heat waves and flooding as well as increases in pests and plant diseases. The effects are unevenly distributed across the world and are caused by changes in temperature, precipitation and atmospheric carbon dioxide levels due to global climate change. In 2019, millions were already suffering from food insecurity due to climate change. Further, the predicted decline in global crop production is 2% - 6% with each decade. In 2019 it was predicted that food prices would rise by 80% by 2050. This will likely lead to increased food insecurity, disproportionally affecting poorer communities. A 2021 study estimated that the severity of heatwave and drought impacts on crop production tripled over the last 50 years in Europe – from losses of 2.2% during 1964–1990 to losses of 7.3% in 1991–2015.
