1- Raw materials.

- Read this:

Raw materials are the resources of the environment that are used in the
industry for the manufacturing of processed products.
Raw materials can be:
- Raw materials of animal origin: they come from farming and
fishing, like for example wool, skin, fish, etc.
- Raw materials of vegetal origin: vegetal (agricultural products) or forest
products (wood).
- Raw materials of mineral origin: the minerals are extracted from the
subsoil and they are transformed into metallic minerals (the metals are
extracted from them, like bauxite from which aluminium is obtained),
non-metallic minerals (like salt, sulphur, rocks used in construction...)
and power minerals (which become energy such as coal, oil...)
Mining is the activity which allows the extraction of mineral resources from the
subsoil. The mines are the places where these minerals are extracted and can
be underground mines or open mines.
and then classify:

And explain what raw materials are use to produce:
- Shoes: leather, rubber and different cloths
- Chairs: wool
- Juice: fruit
- Jewels: gold, silver, bronze and other materials
- Keys: with metallic materials
- Thermometers: mercury and glass
- Windows: glass

2- Renawable energy resources.


3- Case study: The three gorges dam. China.

The facts:
. The three gorges Dam will be over 2 km long and 100 m. high
. The lake will be over 600 km long
. Over 1 million people will have to be removed to make way for the dam and the lake.
. The river Yangtze provides 66% of China’s rice and contains 400 million people.
. The Yangtze drains 1.8 million km2 and discharges 700 km3 of water annually.
Advantages
. It will generate up to 18,000 megawatts, eight times more than the Aswan Dam (Egypt) and 50% more than the world’s largest existing HEP dam, the Itapu in Paraguay.
. It will enable China to reduce its dependency on coal.
. It will supply energy to Shangai (population 13 million), one of the world’s largest cities, and Chongqing (population 3 million), an area with high economic growth.
.It will protect 10 million people from flooding (over 300,000 people in China died as a result of flooding in the 1900s)
. It will allow shipping above the Three Gorges (the dams will raise water levels by 90 m.) and turn the rapids in the gorge into a lake.
. It will generate thousands of jobs.
The protests
. Most floods in recent years have come from rivers which join the Yangtze below the three Gorges dam
. The region is seismically active and landslides are frequent
.The dam may become silted up as a result of increased deposition. To reduce silt load afforestation is needed but resettlement of people will cause more pressure on the slopes above the dam.
. Up to 1.2 million people will have to be moved to make way for the dam.
. Most of the available resettlement land is over 800 m. above sea level and is colder and has infertile thin soils.
. Dozens of towns, such as Wanxian and Fuling with 140,000 and 80,000 people respectively, will be flooded.
. Archaeological treasures will be drowned.
. It will take between 15 and 20 years to build and could cost as much as 70 billion dollars.

Explain with your own words, at least four advantages and four disadvantages of the new dam.
Advantages: It produce more energy than the Awan dam (Egypt) and more than the world´s largest existing HEP dam, the Itapu in Paraguay.
-It´s good for reduce no-renewable resources.
-It supplies energy to Shangai and other cities with more population.
-It is generate thousands of jobs.

Disadvantages:
-1, 2 million people they have to go an other place for live
- Dozens of towns such as Wanxian and Fuling will be flooded.
- Archaeological treasures is drowned.
- The dam are very expensive, it cost as much 70 billion dollars.

4- Write a few lines about the main environmental problems of the planet caused by industrial activity, use text and drawing or photographs. Choose tw

- Acid rain: is rain or any other from of precipitation that is unusually acidic, i.e. elevated levels of hydrogen ions (low Ph). It has harmful effects on plants, aquatic animals and infrastructure through the process of wet deposition. Acid rain is caused by emissions of compounds of carbon, nitrogen and sulfur which react with the water molecules in the atmosphere to produce acids. Governments have made efforts since the 1970´s to reduce the production of sulfuric oxides into the Earth´s atmosphere with positive results. However, it can also be caused naturally by the splitting of nitrogen compounds by the energy produced by lightning strikes, or the release of sulfur dioxide into the atmosphere by phenomena of volcano eruptions.

- Greenhouse effect and Global Warming:
The greenhouse effect is caused by an atmosphere containing gasses that absorb and emit infrared radiation. Greenhouse gases trap heat within the surface- troposphere system, causing heating at the surface of the planet or moon. This mechanism is fundamentally different from that of an actual greenhouse, which works by isolating warm air inside the structure so that heat is not lost by convection. The greenhouse effect was discovered by Joseph Fourier in 1824.
Global warming, a recent warming of the Earth´s surface and lower atmosphere, is believed to be the result of an “ enhanced effect” mostly due to human- produced increases in atmospheric greenhouse gases. This human induced part is referred to as anthropogenic global warming.

1- What is a multinational corporation (MNCs)? A multinational corporation or transnational corporation is a corporation or an enterprise that manages production or delivers services in more than one country. It can also be referred as an international corporation. ILO defined MNC as a corporation which has his managerial head quarters in one country known as the home country and operates in several other countries known as host countries.
2- State the main 5 industrial MNCs and the country they are from.
a)Telefonica – It´s from Spain
b) BBVA- It´s from Spain
c) Movistar- It´s from Spain
d) Repsol- It´s from Spain
e) Santander-It´s from Spain
3- Could ZARA be a multinational? And Citroën? Write a brief repot about them.
ZARA-is the flagship chain storeof Inditex Group owned by Spanish tycoon Amancio Ortega , who also owns brands such as Massimo Dutti, Pulland Bear, Oysho, Uterqüe, Stradivarius and Bershka. The group is headquartered in A Coruña, Galicia, Spain, where the first Zara store opened in 1975. It is claimed that Zara needs just two weeks to develop a new product and get it to stores, compared with a six-month industry average, and launches around 10,000 new designs each year. Zara has resisted the industry-wide trend towards transferring fast fashion production to low-cost countries. Perhaps its most unusual strategy was its policy of zero advertising; the company preferred to invest a percentage of revenues in opening new stores instead.

Citröen-is a French automobile manufacture. Founded in 1919 by André Citröen, it was the one of the world's first mass-production car company outside of the USA. Since 1976 it has been part of PSA Peugeot Citröen, and its headquarters is on rue Fructidor in Saint-Ouen, Seine-Saint-Denis, near Paris. The brand celebrated its 90th Anniversary in 2009.
