Environment- consists of fauna (animals), flora (plants), the water, the air, and the earth
- we distinguish:
NATURAL ENVIRONMENT – all living and non-living things occuring naturally on Earth (all living organisms, soil, rocks, atmosphere, natural resources and physical phenomena)
BUILT ENVIRONMENT – human-made surroundings that provide the setting for human activity (buildings, neighborhoods and cities, infrastructure – water supply, energy networks) – product of human labor

Natural disasters
- cause damage to crops and endanger animals as well as people´s lives and property
Drought – long period without rain - consequences – shortage of food, famine
Flood – a lot of water caused by heavy rains or melted snow in spring - consequences – damage to houses, bridges, roads and other property
Tornado – dangerous, violent, rotating column of air - consequences – severe damage to property, can level the buildings
Earthquake – sudden and violent shaking of the earth caused by changes in the earth´ crust
Volcanic eruption – hot lava and volcanic ash pouring out of the volcano, causing widespread destruction
Tsunami – a series of water waves caused by earthquakes, volcanic eruptions and other underwater explosions - consequences – flooding and devastation of coastal regions

Humans do not always care for the environment as they should. People tend to prefer their own convenience and luxury over a healthy natural environment. They pollute the environment in many ways.
We can devide pollution into three cathegories:
Air pollution
Soil pollution
Water pollution

Air pollution- Traffic – cars produce exhaust
- Smog
- Heavy industry - factories emit SO2
- Acid rain
- Green House gases (CFC) contribute to global warming
(burning fossil fuels in vehicles, power plants´ and factories´ emissions)

Soil pollutionSoil contamination can be caused by:
• Corrosion of underground storage tanks (including piping used to
transmit the contents)
• Application of pesticides and chemical fertilizers
• Mining
• Oil and fuel dumping
• Disposal of coal ash
• Leaching from landfills
• Direct discharge of industrial wastes to the soil
• Drainage of contaminated surface water into the soil

Teacher´s notes :
Page 2/ slide 4 : Pictures: 1) tornado in Oclahoma, 2) volcanic eruption, lava fountain, lava flow, 3) air pollution, heavy industry emissions 4) flood, 5) traffic
Page 4/ slide 6 : Picture Eco vs. Ego - An ecosystem is a group of living things and the whole place where they live. They all live together and need each other. People tend to prefer their own convenience and luxury over a helthy natural environment. They want more cars, bigger houses, the latest computer technologies, etc. to make their life more comfortable. All of this growth pollutes nature and the environment.
Page 6/ slide 8: Air Pollution:Air is essential for life – not only for humans, but also for animals and plants. Although all living beings share the air, only people pollute. Traffic plays a large role in the creation of air pollution. The auto industry is booming. Cars, buses, trucks, motorcycles, aeroplanes are an integral part of our contemporary way of life. They all produce exhaust, which often gets trapped in the cities due to the wind currents created by the cityscape, causing smog in heavy congested areas. Smog, a mixture of smoke and fog, irritates the eyes, throat, and lungs and also damages plants. Another factor is heavy industry. Some factories emit SO2 and the wind spreads it in all directions. When SO2 mixes in the air with rainwater it causes acid rain. Acid rain pollutes the water and the soil, it is very aggressive - it kills trees (makes them grow more slowly, they grow old too quickly and then die), animals and all kinds of metal go rusty. At the same time, Green House gases rise into the air and contribute to the global warming.Picture: Schematic drawing, causes and effects of air pollution: (1) greenhouse effect, (2) particulate contamination, (3) increased UV radiation, (4) acid rain, (5) increased ground level ozone concentration, (6) increased levels of nitrogen oxides.
Page 7/ slide 9: Water Pollution:Factories and power plants don´t pollute only the air alone, but also the ground and water. Many factories do not have an efficient cleaning system and they discharge their waste into the water system. Rivers and oceans are so heavily contaminated by industrial waste that it´s no longer safe to go swimming in some places. We can often see oil slicks (spills) on the surface of the sea caused by wrecks of oil tankers. One tank of oil can pollute several million litres of water, which causes many fish and seabirds to die. Oceans are also becoming our big garbage dumps.Pictures: 1) Shipyard - water pollution from an oil refinery wastewater discharge outlet 2) Raw sewage and industrial waste in a river, 3) A bird covered in oil from the oil spill, 4) solid waste in a lake

Teachers notes :
Page 8-9/ slide 10-11: Soil Pollution:The ground and water are also polluted by conventional agriculture, in which chemical fertilisers are used instead of manure. Application of pesticides an herbicides is very damgerous, too. In addition, we shouldn´t overlook pollution from mining (Mining environmental issues can include erosion, formation of sinkholes, loss of biodiversity, and contamination of soil, groundwater and surface water by chemicals from mining processes. The nature of mining processes creates a potential negative impact on the environment both during the mining operations and for years after the mine is closed.)and normal households. In the majority of houses, chemical based products are used.Pictures: 1) a landfill 2) soil contamination at a disused gasworks, 3) Chile - second deepest open pit copper mine in the world, 4) a cropduster spraying pesticide on a field, 5) a sign warning about potential pesticide exposure.

Answers to the questions on the student´s worksheet:
1) Hurricane(in the Caribbeand and the US) and typhoon(in western Pacific Ocean) – severe tropical storm with high, spiraling wind and heavy rain.
Blizzard - severe winter storm characterized by low temperature, strong winds, and heavy snow.Avalanche - a sudden rapid flow of snow down a slope that has destructive power, in mountainous terrain
avalanches are among the most serious objective hazards to life and property.Hailstorm - rain drops that have formed together into ice, may cause large property damage. 2) A hurricane is a tropical cyclone, occurring in the North Atlantic Ocean or the Northeast Pacific Ocean, east
of the International Dateline. A wind of force 12 on the Beaufort scale, above 118 km/h, is also referred to as a hurricane irrespective of its origin or location.
A typhoon is a mature tropical cyclone that develops in the northwestern part of the Pacific Ocean
3) Major primary pollutants produced by human activity include:Sulphur oxides (SOx) - especially sulfur dioxide, a chemical compound with the formula SO2. SO2 is produced by
volcanoes and in various industrial processes. Since coal and petroleum often contain sulfur compounds, their combustion generates sulfur dioxide.
Nitrogen oxides (NOx) - especially nitrogen dioxide are emitted from high temperature combustion, and are also produced naturally during thunderstorms by electrical discharge. Can be seen as the brown haze dome above or plume downwind of cities. Nitrogen dioxide is the chemical compound with the formula NO2. It is one of the several nitrogen oxides. This reddish-brown toxic gas has a characteristic sharp, biting odor. NO2 is one of the most prominent air pollutants.
Carbon monoxide (CO)- is a colourless, odorless, non-irritating but very poisonous gas. It is a product by incomplete combustion of fuel such as natural gas, coal or wood. Vehicular exhaust is a major source of carbon monoxide.
Carbon dioxide (CO2) - a colourless, odorless, non-toxic greenhouse gas also associated with ocean acidification, emitted from sources such as combustion, cement production, and respiration. It is otherwise recycled in the atmosphere in the carbon cycle.

Answers to the questions on the student´s worksheet:
4) China, United States, Russia, Mexico, and Japan are the world leaders in air pollution emissions.
5) Open answers: The main problem is water pollution/air pollution, etc. There are many mines, factories (ironworks) in my region, and many people drive cars, burn coal, etc.Air pollution causes - the growing industry and increased traffic, as well as the use of low-quality fuels in household heating.
