protection
Agnieszka Zwolińska and Antek Sadkowski

2. What is the environmental
protection?
It is a practice of protecting the natural
environment on individual, organizational or
governmental levels, for the benefit of both
the natural environment and humans.

3. The phenomenon of decline in the concentration
of ozone ( O3) in the stratosphere, Earth's
Atmosphere . Stratospheric ozone absorbs some
ultraviolet radiation reaching Earth from the sun.
Some types of ultraviolet radiation are harmful to
living organisms because they can damage cells
(burns) and the genetic material of cells. In
humans and animals may induce neoplasia. The
formation of the hole is usually associated with
anthropogenic emissions of CFCs .

4.  Air pollutants are the main causes of global
environmental threats. There is the air
pollution when the level of all the gas
substances (solid or liquid) is higher than the
average content.
 The growing demand for energy made from
burning the main source of atmospheric
pollutants of anthropogenic origin. The most
important are:

5. • sulfur dioxide (SO2)
• nitrogen oxides (NxOy)
• carbonaceous particulate matter (X2)
• Volatile organic compounds
(benzopyrenes)
• Carbon monoxide (CO)
• Carbon dioxide (CO2)
• tropospheric ozone (O3)
• lead (Pb)
• dust suspended

6.  low emission
 chemical conversion of fuels
 extraction and transport of raw materials
 chemical industry
 refining industry
 metallurgical industry
 cement
 the storage of raw materials

7. Natural sources of air pollution
• volcanoes
• chemical weathering of rocks
• steppe and forest fires
• lightning
• cosmic dust
• biological processes

8. Air pollutants are absorbed in humans mainly during
breathing. Contribute to the formation of respiratory
diseases , as well as reproductive disorders and allergies. In
the cultural environment of human air pollution cause
corrosion of metals and construction materials. They act
negatively also on the world of plants , disrupting the
processes of photosynthesis , transpiration and respiration
. Secondarily contaminate water and soil . The global
impact on climate change. Air pollution also increase the
acidity of drinking water. This causes an increase in the
content of lead, copper , zinc, aluminum , cadmium and
even in the water supplied to our homes . The acidified
water damage water installations , flushing of the various
toxic substances.

9. Acid rain
Is a rain or any other form of precipitation that
is unusually acidic, meaning that it possesses
elevated levels of hydrogen ions (low pH). It
can have harmful effects on plants, aquatic
animals and infrastructure. Acid rain is caused
by emissions of sulfur dioxide and nitrogen
oxide, which react with the water molecules in
the atmosphere to produce acids.

10. Each person annually produces a large
amount of garbage, of which only a small part
will be decomposed. The rest will have to be
stored for many years. Add to this industrial
waste, including radioactive and toxic that
inappropriate storage can lead to
contamination of the soil.

11. How to protect the environment?
1. Use both sides of paper for writing or drawing. In
this way you protect the tree before cutting and you
produce less garbage!
2. Turn off the water while brushing your teeth. Take a
short shower than a bath. Tighten the taps. In this
way you save water!

12. 3. Switch off the lights when you leave a room,
turn off the TV, radio, computer, when you no
longer use them. In this way you save energy!
4. Going shopping bring your own bag instead
of bringing the store plastic bags. In this way,
you produce less garbage!

13. 5. Try to use environmentally friendly means of
transport. If you have to overcome the short
distance walk on foot or ride a bicycle. In this
way you will help to lower poisoning the air!
6. Talk to your parents and friends about what
you can do together to protect the
environment. In this way you impact on
someone's consciousness, teach others how
to be environmentally friendly!
