Light Industry

Light industry is industry that is usually less capital intensive than heavy industry, and is more consumer-oriented thanbusiness-oriented (i.e., most light industry products are produced for end users rather than as intermediates for use by other industries). Light industry facilities typically have less environmental impact than those associated with heavy industry, and zoning laws are more likely to permit light industry near residential areas. It is the production of small consumer goods.

Ventajas y Desventajas del petróleo

Ventajas del petróleo

Entre las principales ventajas que tiene el petróleo se encuentran:

• Muy versátil: se trata de un material muy versátil del que se extraen infinidad de elementos como plásticos, gasolina, etc.
• Derivados del petróleo: casi todos los derivados del petróleo son utilizados para satisfacer las necesidades de energía del mundo.
• Fertilizantes sintéticos: un alto porcentaje de los fertilizantes sintéticos provienen del petróleo.

Desventajas del petróleo

Entre las principales desventajas que tiene el petróleo se encuentran:

• Alto precio: su obtención resulta muy cara respecto a otro tipo de energías como las energías renovables.
• Riesgo ecológico: la extracción del petróleo conlleva un gran riesgo ecológico y medioambiental.
• Lluvia ácida: se genera lluvia ácida asociada a la quema de petróleo por la producción de óxidos de nitrógeno.
• Almacenaje seguro: es necesario el uso de un espacio seguro para el almacenaje del petróleo en destino.
• Transformación materia prima: para poder utilizar el petróleo es necesario que pase un proceso de destilación previo a su uso.
• Calentamiento global: la transformación para su uso provoca un importante efecto invernadero y un aumento del calentamiento global.
• Fuente de energía agotable: al contrario que pasa con las energías renovables el petróleo es una fuente de energía que se agotará al cabo de unos años.
• Contaminación: a diferencia de lo que ocurre con otros tipos de energía el uso del petróleo puede causar una alta contaminación debido a la gran cantidad de CO2 que emite a la atmósfera al quemar los combustibles fósiles

Importance of water

With two thirds of the earth's surface covered by water and the human body consisting of 75 percent of it, it is evidently clear that water is one of the prime elements responsible for life on earth. Water circulates through the land just as it does through the human body, transporting, dissolving, replenishing nutrients and organic matter, while carrying away waste material. Further in the body, it regulates the activities of fluids, tissues, cells, lymph, blood and glandular secretions.

       An average adult body contains 42 litres of water and with just a small loss of 2.7 litres he or she can suffer from dehydration, displaying symptoms of irritability, fatigue, nervousness, dizziness, weakness, headaches and consequently reach a state of pathology. Dr F. Batmanghelidj, in his book 'your body's many cries for water', gives a wonderful essay on water and its vital role in the health of a water 'starved' society. He writes: "Since the 'water' we drink provides for cell function and its volume requirements, the decrease in our daily water intake affects the efficiency of cell activity........as a result chronic dehydration causes symptoms that equal disease...

Farming as a system

“Farming system” therefore designates a set of agricultural activities organized while preserving land productivity, environmental quality and maintaining desirable level of biological diversity and ecological stability. The emphasis is more on a system rather than on gross output.

In other words “farming system” is a resource management strategy to achieve economic and sustain agricultural production to meet diverse requirement of the farm household while preserving the resource base and maintaining high environmental quality. The farming system in its real sense will help the following ways to lift the economy of Indian agriculture and standard of living of the farmers.

Crop farming

Crop farming is the cultivation of plants for food, animal foodstuffs, or other commercial uses. A variety of techniques including organic production methods can be used to manage crops. People may enter this career through a family business, by training on a farm with experienced farmers, or by attending college to get a degree in agriculture or a related subject. It can involve long hours and harsh working conditions, along with unpredictable profits from year to year, which can be stressful for farmers.

The types of crops grown can depend on environmental conditions, market demands, and preference. Some crops have a limited growth range dependent on temperatures, available water supply, pests, and other factors. Others may be cultivated in a wider range of conditions. Crop farmers test the soil and assess their land to determine what kinds of products they can grow, and narrow down that list to determine what would be commercially viable. If the market demand for cotton is high, for example, it might be a profitable crop to plant.

Plants grown for food, like rice, wheat, and vegetables, are one form of crop farming. It is also possible to cultivate plants such as alfalfa that will be used to feed animals. Some farms have a combination of crops and animals, using the crops they grow to feed their livestock.
