The causes of endangered animals on Earth are not connected with:
- diseases of civilization
- mining and quarrying
- industrial accidents
The greenhouse effect is
- one of the sources of danger to the existence of life on Earth
- important for the correct operation of the various habitats
- caused by excessive amounts of pollen and dust particles
in the air
Acidification of soils and waters is caused by
- acidic precipitation/ acid rain
- increased influence of UV radiation
- increased methane content in the atmosphere

The greenhouse effect is
- caused by the presence of so-called. greenhouse gases in the atmosphere
- important for the presence of so-called. greenhouse gases in the atmosphere
- observed only in cold regions of Earth
The ozone layer
- protects life on Earth
- prevents overheating of the Earth's surface
- transmits to Earth ultraviolet radiation
Acid rains
- are formed in the atmosphere from sulphur dioxide and from nitrogen monoxide
- are formed in the atmosphere from sulphur monoxide and from nitrogen monoxide
- are formed by oxidation in an atmosphere of carbon dioxide and methane
Carbon dioxide
- gets into the atmosphere by burning fossil fuels
- is one of the greenhouse gases
- is important for photosynthesis
Eutrophication of water is
- an enrichment of water by nutrients for organisms connected with photosynthesis
- an enrichment of water with nutrients for fish
- an enrichment of water by nutrients for all water organisms
As bio-indicators of the environment are not suitable
- a rat
- an enrichment of water with nutrients for fish
- an enrichment of water by nutrients for all water organisms
