Environmental problems
Exhaustion =
Removing substances from the environment
Pollution =
Adding substances to the environment
Slide 6 - Slide
Slide 7 - Video
Exhaustion
Raw materials
- Oil, fossil fuels, sand and metal ores.
Monoculture
- Growing the same plants every year
- Soil exhausted = not enough minerals for new plants.
Slide 8 - Slide
Slide 9 - Video
Pollution
Fertilize land (add minerals to the soil)
- Nitrogen is an important mineral for fertilization.
Nitrogen ends up in groundwater and air -> Air pollution
Slide 10 - Slide
Assignment pollution
Scan in 2 minutes the text about pollution.
We are going to watch a video about pollution.

Water pollution
- Chemical pesticides against insects end up in the water.

The greenhouse effect
Greenhouse effect:
The blocking of heat radiation by greenhouse gases.
Enhanced greenhouse effect:
Burning fossil fuels -> Increased carbon dioxide in the atmosphere. More heat remains on earth.
Slide 16 - Slide
Natural/enhanced greenhouse effect
(versterkt) broeikaseffect
Broeikasgevaar
Slide 17 - Slide
Climate change
The average weather type over a long period has changed
Sea level rise is a consequence of climate change.
Drought
- deserts are getting bigger
Slide 18 - Slide
Consequences of climate change
Salinification:
reduction in the amount of fresh water and rising sea levels lead to salinification of rivers and therefore agricultural land.
Slide 19 - Slide
Monoculture: Is it a Cause or a Consequence of Exhaustion? Explain
Slide 20 - Open question
Name a cause and a consequence of climate change
