Environment

1. Pollution
   • air
     • the biggest problem in large cities
     • is caused by smoke from factories, dust, smells to car and lorry exhaust and harmful chemical waste
   • the greatest problem is smog
     • with water pollution is a big danger
     • water – contamination by industry, coal mines
     • soil
       • contamination by
         • chemicals
         • pesticides (which kill insects)
         • lead
         • acide rain,…

2. Trees
   • are important for our life
   • are the lungs of our planet
   • give out the oxygen
3. Rain forest
   • are being destroyed for firewood and building materials
   • are production of oxygen
   • animals are losing their homes and dying out
   • people need more space, factories, paper and wood so they cutting trees and rain forest
4. Global warming
   • is caused by greenhouse effect
   • climate changes and it is dangerous for people and animals
   • the temperature and the sea level are rising
   • icecaps are melting
   • floods
5. Floods
   • is caused by long heavy rains or whena lot of snow melt in the spring and water run down from mountains
   • are damaged houses, bridges, roads and killed people and animals who don’t run away in time
6. Ozone layer
   • is in the atmosphere
   • protects life on Earth from (against) ultraviolet rays – skin cancer is caused
   • people protect to use creams, don’t sunbathe along time,…
   • It is caused by the use of gas (plynový) freons
   • The hole is caused by the chemicals and it is getting larger.
7. Endangered species
   • are hunting by people for skin, meat and money
   • are dying out because the environment is wrong
   • haven’t got to drink and eat because people are cutting rain forest
8. Waste
   • we should sort and recycle (use again)
   • nuclear waste is dangered and radioactive
     • they should take in space or another country
     • dump into the sea
     • burry into the ground

9. Earthquake
   • is caused movement of the litospheric bords and explosions of volcanoes
   • bulding fall down and everybody is in danger
   • under the ocean can cause a big tidal wave
   • volcanoes produce a lot of dust, smoke and lava
     • pours out and burns everything

10. Smog
    • we can’t breathe
    • is very unhealthy
    • is in larger cities
11. Acide rain
    • kills fish and trees
12. Another problems of today’s world
    • famine in Africa
    • terrorism
    • illnesses – people infected with HIV virus
    • life in big cities – overcrowded, overpopulated

What can we personally do to protect the environment?

• save energy (switch off the light when leaving)
• save water (have a shower than a bath)
• sort the waste – sort out the waste and put in into the containers
• use the public transport or bike
• put litter only into litter bins (not in the streets)
• we should try to use alternative sources of energy – solar, water, wind, geothermal and perhaps tidal energies
