Environment
- 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,…
- contamination by
- air
- Trees
- are important for our life
- are the lungs of our planet
- give out the oxygen
- Rain forest

- 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
- Global warming
- is caused by greenhouse effect
- climate changes and it is dangerous for people and animals

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
