2- Renewable energy resources

1-E)Solar

Energy from sunlight is captured in solar panels and converted into electricity. Advantages: Potentially infinite energy supply. Disadvantages: Manufacture and implementation of solar panels can be costly.

2-A)Wind

Wind turbines(modern windmills) turn wind energy into electricity. Advantages: Potentially infinite energy supply. Disadvantages: Manufacture and implementation of wind farms can be costly.

3-F)Tidal:

The movement of sea water in and out drives turbines. Advatages: a lot of energy is generated this way. Disadvantages: Construction can be costly.

Maybe opposed by local or environment groups.

4-B)Geothermal:

It is possible to use heat from under the earth´s surface in volcanic regions. Steam can be used for heating or to power turbines creating electricity. Advantages: Potentially infinite energy supply. It is used successfully in some countries, such as New Zeland. Disadvantages: Can be expensive to set up. Only works in areas of volcanic activity.

5-C) Hydro-electric-power(HEP):

Energy harnessed from the movement of water through rivers, lakes and dams. Advantages: Creates water reserves as well as energy supplies. Disadvantages: Costly to build. They can cause the flooding of surrounding communities and landscapes. Dams have major ecological impacts.

6-D) Biomasa:

An organic material which can be burnt to provide energy (heat or electricity). Advantages: It is a cheap source of energy. Disadvantages: When bumt, it gives off atmospheric pollutants,including greenhouse gases.

CAP:The Common Agricultural Policy is a system of European Union agricultural subsidies and programmes.Reforms of the system are currently underway reducing import controls and transferring subsidy to land stewardship rather than specific crop production.

BSE: Bovine spongiform encephalopathy, commonly known as mad-cow disease (MCD), is a fatal, neurodegenerative disease in cattle, that causes a spongy degeneration in the brain and spinal cord.

GM FOODS: Genetically modified (GM) foods are foods derived from genetically modified organisms. Genetically modified organisms have had specific changes introduced into their DNA by genetic engineering, using a process of either Cisgenesis or Transgenesis.

Green Revolution refers to the transformation of agriculture that began in 1945, largely due to the life work of Norman Borlaug. One significant factor in this revolution was the Mexican government's request to establish an agricultural research station to develop more varieties of wheat that could be used to feed the rapidly growing population of the country.

THE IMPORTANCE OF AGRICULTURE.

The Agriculture is important. Before, was more important.But today is even, because the agriculture provides occupation. About 45% of the world workforce was employed in the agriculture. The alimentary production continues increasing like the harvests by hectare,too the trade in agricultural products has increased and the Agriculture provides the base

of a lot of manufacture and industries of service and alimentary and a variety of services.

FARMING TYPES

A) Modern Mediterrenean agriculture.

D) Shifting cultivation.

E) Dry and extensive agriculture.

F) Market gardening.
