The current situation of food crisis may lead the advance of transgenic crops. The number of people who suffer from hunger has grown last year of 848 million at 923. It is due above all to the increase in the price of food, which according to the United Nations agriculture and food Organization (FAO), remains at extremely high levels in the countries poorest and importers of cereals. 22% Of imports of cereals correspond to countries in Africa, where 30% of its growing population suffers from chronic hunger. There is no doubt that we must increase food production, although hunger is not by prices that reached both by lack of food. GMOs can be important in terms of production, but its use and impact still remain controversial. The early 1970s green revolution succeeded in tripling the production of food in India.
Thanks to the use of hybrid seeds, fertilizers, and pesticides overcame painful cycles of famine and were done self-sufficient in food. Now, with new generations of GM, maybe it could be a new revolution. But African agricultural production does not require only these changes. In addition would have to expand investments, new technologies and research seeds crossings, as India and China did in his time. There are investigations of about 20 kinds of crops, including tomatoes, rice and potatoes. At the moment, genetically modified cotton, corn or soybeans are planted. Expected to make crops more resistant to pests, with higher nutritive capacity and better productive results.
There are organisms that have placed their hopes in this type of farming. It is the case of the international service for the acquisition of technology applications of Agrobiotec (ISAAA), which promotes the use of GMOs. In its latest report ensures that between 2006 and 2015 will double the number of countries, cultures and hectares and that biotech crops will be the most important contribution to the The Millennium development goals of reducing poverty and hunger in half by 2015.
The Alliance for green revolution in Africa (AGRA), based in Nairobi and sponsored by Kofi Annan aims to increase the diversity of seeds, trying to make them more resistant to pests and drought. In fact, on the African continent is being used already a resistant corn in areas where almost no water. Although AGRA they usually opt for conventional crossings, this Alliance, although usually opt for conventional crosses, not opposed to GMOs. They will invest in them as the countries of the region are accepting its use and developing own thereon laws. It is expected that within two years, Egypt and Burkina Faso have joined South Africa in the use and marketing of these products.
However, there are environmental organizations such as friends of the Earth, the Group ETC and GRAIN that warn about this kind of approach. They argue that the increase in production is not so great if we take into account the costs of the farmer in patented seeds, herbicides and insecticides. For GRAIN, the current situation of food crisis could be used by advocates of GMOs to take over the market. It is important to know that 10 companies most involved in this type of crop, 4 of them are also agrochemical, marketed herbicides and insecticides. The business is complete. Another of the critical is that, by replacing traditional varieties by commercial improved, causes a genetic erosion.
Improve productions in exchange for loss of genetic diversity. FAO is not pronounced clearly towards GMOs. Your in charge of agricultural research Andrea Sonnino says that they are a powerful tool that can have many benefits, but also risks to health and the environment. It must be examined case by case, see the cost-benefit ratio is positive, and in addition local research projects should be made. It is improving the living conditions of the populations in a manner consistent with the conservation of natural resources, says Elena Espinosa, Spanish Minister of environment. Biotechnology is an instrument, one ally. We can not disregard a priori GMOs, but it is transcendental scientists ensure that they are harmless to health and biodiversity.
experts use this methodology that allows to transform data into information that can be useful for managers to make their decisions. It is not any activity, requires constant training in technological language, and that is why they can sell your expertise on the subject. In turn, according to a study conducted by The Association of Professional Futurists, organism composed of 20, 000 professionals of various disciplines, in the market are being detected new requirements which will result in different for developing knowledge. Here is a list of some posts that could be in the sights of companies by 2015. -Chemistry to another level. Laboratories need personnel trained in sterilized material, adjust appliances, perform analysis, prepare the test tubes, organize and preserve biological specimens, understand quality standards in companies, between other tasks. Will require a graduate of this race, that makes a specialty in the topics described. -Genetic counselor medical.
General practitioners and patients will need to an expert who will advise them on the best trends of treatment to the pathology of the person according to their genome. These professionals must combine studies of medicine and biotechnology. -Nanomedico. It will be a physician with training in nanotechnology capable of developing and using devices that improve health. It is a more complex profile, you can combine studies of medicine, robotics engineering, biotechnology and Biomedicine.
-Agro-farmaceutico. Based on genetic modification, these professionals could work in activities such as vegetable crops and breeding of animals with therapeutic substances. -Technician in energy efficiency. You will be responsible for guidance on how to reduce energy consumption in businesses and homes. It will advise on the best location of the buildings and the most suitable material to use in function the temperature and the weather conditions in different regions. -Manager of communities. The companies will need who advise them on their participation in social networks; Select the most appropriate corporate profile forums and analyze the contributions of users. This professional needs to dominate, at least, English and various skills technology to move in these communities, with a corporate twist.
Avoriaz – one of the best resorts in the network of trails Portes du Soleil – "Gateway of the Sun." And, despite the fact that this ski area brings together twelve different ski stations, namely Avoriaz is the most attractive ski resort, which annually gathers a large number of people seeking a quiet and high-quality leisure. It is built on a picturesque cliff, so that here it is impossible to reach by car. And in general the use of motor vehicles in this area is not allowed to be a plus for those seeking solitude with nature: to reach the residential building, you will need to use a snowmobile or special sleds, horse-drawn. All buildings in the town – quite high, but finished in wood, which further emphasizes the complex ecology. However, a large selection of hotels in Avorize you will not. But there are many comfortable apartments and comfortable chalets, which can comfortably accommodate and relax after a day spent outdoors.
Avoriaz is a recognized worldwide reputation as the European capital snowboard, but benefits of the local trails and appreciate the quality of snow and skiers, regardless of their level of training. The total length of tracks – more than 150 km. In terms of complexity, they are divided by color: 5 black 15 – red 22 – blue, and 5 – green. For snowboarders there are just three super snowpark, and for those who prefer a flat ski – a special route length of 17.5 km and allow to fully appreciate the beauty of the pristine nature of these places. For convenience of tourists creators of the complex have provided 38 lifts: cable car, two gondolas, nineteen and sixteen ski chairlifts. For those who do not really feel confident on skis Avoriaz offers training in three ski schools. In them you are waiting for more than 150 experienced instructors.
The development of a high resolution microscope compact, small enough have completed to fit on the tip of a finger. This microscopic microscope operates without lenses but has the power of magnification of a light microscope of high quality, can be transported with obvious ease and use anywhere to analyze blood samples in tests for detection of malaria, or analyze water supplies in order to verify the existence of giardia and other pathogenic organisms, and can be manufactured in series for around $10. (NC & T) Changhuei Yang developed the device, with the help of his colleagues at Caltech. The microscope is truly compact; Indeed, it may be installed on a mobile phone. In addition, it is able to obtain the necessary lighting for viewing from just from sunlight. All These features make it very attractive for sanitary applications in the third world.
The new instrument combines the technology of traditional computer chip with microfluidics, fluids to incredibly small scales. A microscope full optofluidico on a chip is about the size of a coin of twenty-five cents, although the part of the device that produces images of objects is only the size of the nose of George Washington in that currency. Yang is now holding negotiations with biotechnology companies to manufacture in series chip. The platform on which the chip integrates may vary, depending on the needs of the user. For example, the health personnel in rural areas could carry adequate models to form part of the portable medical instruments, empowering professionals to verify in situ if an individual suffers from malaria, among other things. We could build hundreds or thousands of microscopes optofluidicos on a single chip, which would allow get the images of many organisms for immediate analysis, explains Xiquan Cui, of the research team. In the future, microscopes in chips could be incorporated into devices that could be implanted in the human body. An analysis with an implantable microscope system is capable, autonomously, monitor what comes through the bloodstream and isolate loose cancerous cells that is found, thus providing important information for diagnosing and helping to prevent the spread of cancerous cells.
