Statistics show that around half the world’s production of root crops is consumed as food. These statistics vary from one country to another.
Our ancestors found the first root crops when they were still hunter gatherers, and history is witness to the fact that what these first cultivators found in the wild was what they first experimented with as cultivators. The earliest agricultural system in parts of Africa was based on root crops. Recent studies have shown that the ancient Mayan civilization grew crops such as sweet potato, yams and cassava; so too did some African tribes like the Bantu. Early civilizations in Asia, Africa and South America seem to have been the first to sow and harvest root crops that had previously been gathered in the wild.
“A healthy diet is the cornerstone of a healthy lifestyle,” says Dr.Weil. Root vegetables have been described as “some of the most overlooked and underappreciated foodstuffs ......nutritional storehouses, hidden treasures worthy of notice” ( Dr. Weil, drweil.com, n.d.) A large proportion of the world’s food supply today consists of root crops that are also used as animal feed. Industrial products such as starch and distilled spirits as well as a wide range of other minor products also are made from root crops. Around half of the supply of root crops grown globally is used for human consumption. This utilization pattern varies from one country to another, with developing nations using a greater percentage of these crops for food, while the developed nations use a larger percentage for animal feed and industrial use.
Agro climatic factors define where different root crops are produced. Potatoes seem to have first been cultivated in the Andes, but today are grown at lower altitudes and in warmer climates. Sweet potatoes too are grown in a wide variety of climates and altitudes, but yams are mostly grown in Africa. The fact that these root crops that were cultivated by our early ancestors survive as an

Weather Phenomenon vs. Crops Prices.
Commodity prices are generally influenced by a number of economic factors, the most common being the demand and supply of the commodity in the market. Nevertheless, the forces of demand and supply are also influenced by other macroeconomic factors such as the prevailing weather patterns at any given time that can either increase or reduce the production of a particular commodity.
The gene is inserted through a vector and is usually derived from bacteria because they are expected to confer a useful characteristic such as resistance to a pest or pesticide. Vector DNA and the donor DNA both are cut with the same restriction enzyme which produces hanging ends also known as sticky ends on both of the DNA molecules.
The author states that there are different ways of moving genes in both animals and plants in order to produce the desired outcome. Due to improvements in technology these days, genetic modification can be done in laboratories. When this technology is performed on crops, and the plants are regarded as Genetically Modified Crops (GM crops).
The present paper looks at a typical case involving two states on the breach of international environmental policies. As it is well known, even though the sovereignty of all states is highly respected, the need for these states to operate within their confines is also enshrined in most international regulations and provisions.
Government agencies support tolerance for many cultures through backing Asian American and Hispanic heritage weeks (Owen, 2005). However, multiculturalism continues to be a source of problems in American schools. Approximately half of American population perceives that government agencies have directed efforts maintenance of separate ethnic and racial practices such as bilingual education.
In the United States, for instance, it is estimated that genetically engineered crops represent about 60 percent of all American processed foods (Coleman). This spread and popularity of genetically modified food in the US has strongly affected farmers. According to a recent study that was conducted by the National Center for Food and Agriculture, it is found that “farmers in the United States investing in biotech products harvested 5.3 billion additional pounds of crops and realized $22 billion in increased income” (Coleman).
While some people think that men should be strong and women passive, it’s evident that past social roles affect people’s thoughts about gender. The challenge and its impact Girls for a long time have been made aware through socialization found in schools that they are not equal to boys.
