What percentage of a scrapped car do you think is recyclable?

1. 35%
2. 55%
3. 75%
4. 95%

Which type of organism can turn organic waste into compost?

1. Plants
2. Animals
3. Fungi

Our waste

domestic waste = waste that is produced by households

• Recycling and reuse
• Incineration plants = factories with ovens in which non-recyclable waste is burned after metals have been removed
• Landfill sites = dumpsites

Fossil fuels

Air pollution

emission = the release of waste gases

Consequences of pollution

1. Fine (dust) particles in the air

2. Smog = dirty fog made of particulate matter and waste gases

3. Acidification

Consequences of soil acidification

1. Minerals dissolve and wash away to where they are unreachable for plant roots.

 

2. Toxic substances damage the root hairs. Plants fall ill as a result.

Carbon cycle

CO2 in the atmosphere

Activity of an enzyme depend on temperature
