why is air so important

- oxygen- breathing- photosynthesis

Page 2: Prezentcija  engleski..(1)

- once people have breathed much cleaner air than this we breathe today

- development of the industry has resulted in the increase in pollutants

- exhaust of cars and factories, smog, greenhouse gases and acid rain all contributed to the air pollution

What is polluting the air?- exshaust (from cars, factories, construction works and car manufacturing)- products in sprays- greenhouse gases- acid rain

What do the pollutants do?- destroy soil- pollute water- damage animate and inanimate world

Recently, we were informed through the media about air pollution in our country. Every day there is a significant increase of pollution in oil processing refinery in Bosanski Brod, which reaches the limit of processed oil. In Bosanski Brod they claim that the air is clean, but according to the State Meteorological Bureau air is everything but clean.

Apart from Slavonski Brod air is pollutied in Sisak. It is excessively polluted by sulfar dioksidomm that is produced by the oil rafinery.

- smog is air pollution in the

form of smokeand fog

- it is resultingfrom the

combustion of coal (fuel

sediment) and other fuels

greenhouse gases are those that cause the greenhouse effect.

- the most powerful greenhouse gas is water vapor

Forest is a perfect ecological factory

- cutting results in soil erosion and loss of natural balance- acid rain causing great damage to trees which we use for:- heating- ecosystems- paper- oxygen

What does rain taste like? Unfortunately apart from normal rain there is also acid rain and its acidity affects the forest and the soil. Exhaust of factories and cars going into the atmosphere makes the steam acid, resulting in acid rain. Soil changes the composition of plants that are found in the soil which than can not grow, and the animals that feed on these plants can not survive without them.

Pollution should be stopped because our forests are important for the ecosystems, oxygen, paper production and firewood.

STOP POLLUTIoN

Page 14: Prezentcija  engleski..(1)

to preserve the forests, apart from stopping pollution we should regularly take care of trees that should be cut- before the young trees grow 10-20 cm old trees shouldn’t be cut- that’s the sustainable way of preserving forests

Unlike some poisonous plants there are plants that absorb harmful substances, and you probably have them in your home. These are the palms, ferns, English ivy, and orchids. They are especially cultivated because they have a special effect on our health and the environment.
