Genetically modified Foods



GM foods or Genetically Manufactured also known as Genetically Engineered foods are the result of altering an organism’s gene by inserting an individual gene taken from another organism to improve its characteristics. Examples of these are crops which are immune to insects, pesticides and drought, crops which stay fresh longer, crops growing quicker and bigger, salmon and trout growing bigger and 6x faster and more milk produced by cows.

In the present, there are a lot of GM foods which are available in the market that we are not aware of.



Some of the well-known bad effects of GM food consumption are the development of diseases and allergic reaction for humans. Farmers give cows antibiotics to cure them from udder infection. This massive amount of antibiotics inside the cow can be found in the dairy products which are produced. When consumed, this may cause allergic reactions and immunity to antibiotic. Severe exposure to this chemical may also lead to lymphoma, arthritis and leukemia.

Plants which are immune to insects have developed their very own pesticides which kill pests and other beneficial insects like honeybees and caterpillars of Monarch butterflies causing a disruption in the natural balance of the ecosystem.
GM foods can be considered as ‘bad, because of its harmful effects to humans, animals and plants. Although it can become a great solution to the worldwide food price hike, the project itself has not yet been fully developed. It still has a lot of loopholes which we cannot just undermine.

Cuba

Cuba


Cuba, officially the Republic of Cuba, is an island country in the Caribbean. The nation of Cuba consists of the main island of Cuba, the Isla de la Juventud, and several archipelagosHavana is the largest city in Cuba and the country's capital. Santiago de Cuba is the second largest city. To the north of Cuba lies the United States (90 miles away) and the Bahamas,Mexico is to the west, the Cayman Islands and Jamaica are to the south, and Haiti and the Dominican Republic are to the southeast.



Spanish colonization and Independence wars.



Christopher Columbus landed on Cuba's northeastern coast near what is now Baracoa on October. He claimed the island for the new Kingdom of Spain,In 1511, the first Spanish settlement was founded by Diego Velázquez de Cuéllar at Baracoa; The Spanish enslaved the approximately 100,000 indigenous people who resisted conversion to Christianity, setting them primarily to the task of searching for gold.

In the 1820s, when the rest of Spain's empire in Latin America rebelled and formed independent states, Cuba remained loyal,This loyalty was due partly to Cuban settlers' dependence on Spain for trade, their desire for protection from pirates and against a slave rebellion.
Independence from Spain was the motive for a rebellion in 1868 led by Carlos Manuel de Céspedes . De Céspedes, a sugar planter, freed his slaves to fight with him for a free Cuba.

After the Spanish-American War , Spain and the United States signed the Treaty of Paris (1898) , by which Spain ceded Puerto Rico , the Philippines , and Guam to the United States for the sum of $20 million .Under the same treaty, Spain relinquished all claim of sovereignty over Cuba. 


Cuba, climate.

The local climate is tropical, moderated by northeasterly trade winds that blow year-round. In general (with local variations), there is a drier season from November to April, and a rainier season from May to October. The average temperature is 21 °C (69.8 °F) in January and 27 °C (80.6 °F) in July. The warm temperatures of the Caribbean Sea and the fact that Cuba sits across the entrance to the Gulf of Mexico combine to make the country prone to frequent hurricanes. These are most common in September and October. 



Culture.

Cuban culture is influenced by its melting pot of cultures, primarily those of Spain and Africa. Sport is Cuba's national passion. Due to historical associations with the United States, many Cubans participate in sports which are popular in North America.
Music.
Cuban music is very rich and is the most commonly known expression of culture. The central form of this music is Son, which has been the basis of many other musical styles like salsarumba and mambo and an upbeat derivation of the rumba, the cha-cha-cha.
Cuisine.
Cuban cuisine is a fusion of Spanish and Caribbean cuisines. Cuban recipes share spices and techniques with Spanish cooking, with some Caribbean influence in spice and flavor.The traditional Cuban meal is not served in courses; all food items are served at the same time. The typical meal could consist of plantains, black beans and rice, ropa vieja,cuban bread, pork with onions, and tropical fruits. Black beans and rice, referred to as Platillo,Moros y Cristianos, and plantains are staples of the Cuban diet. Many of the meat dishes are cooked slowly with light sauces. Garlic, cumin, oregano, and bay leaves are the dominant spices.

Climbing
 is the activity of using one's hands and feet (or indeed any other part of the body) to ascend a steep object. It is done both for recreation (to reach an inaccessible place, or for its own enjoyment) and professionally, as part of activities such as maintenance of a structure, or military operations. 





Rock climbing
 is an activity in which participants climb up, down or across natural rock formations or artificial rock walls. The goal is to reach the summit of a formation or the endpoint of a pre-defined route without falling. Rock climbing competitions have objectives of completing the route in the quickest possible time or the farthest along an ever increasingly harder route. Rock climbing is similar to scrambling (another activity involving the scaling of hills and similar formations), but climbing is generally differentiated by its sustained use of hands to support the climber's weight as well as to provide balance. 







Rock Climbing equipment
Ropes used for climbing can be divided into two classes: dynamic ropes and low elongation ropes (sometimes called "static" ropes). Dynamic ropes are designed to absorb the energy of a falling climber, and are usually used as Belaying ropes. When a climber falls, the rope stretches, reducing the maximum force experienced by the climber, their belayer, and equipment.  

Quickdraws (often referred to as "draws") are used by climbers to connect ropes to bolt anchors, or to other traditional protection, allowing the rope to move through the anchoring system with minimal friction. 
A harness is a system used for connecting the rope to the climber. Most harnesses used in climbing are preconstructed and are worn around the pelvis and hips, although other types are used occasionally.
