Slide 3 - Quiz

Slide 4 - Slide

How does the production of meat lead to deforestation of the tropical rainforest?
 

  • Production of 1 kilo of meat:  50 tot 250 m² is needed
  • More space is needed for the animals and for fields of animal feed 
  • Deforestation tropisch regenwoud 

Slide 5 - Slide

Tropical rainforest and agriculture: Amazon 

Slide 6 - Slide

Explain the difference between large-scale farming and intensification

Slide 7 - Open question

What is changing in the food industry?
Quite a lot: organic framing, large-scale framing and intensification.
Organic farming
Organic farming uses fewer pesticides and gives animals more space
Large-scale farming
Companies make a lot of the same food. This is the most efficient. 
Intensification
Companies that use knowledge and money for higher yields (opbrengsten). They use a lot of modern technology.

Slide 11 - Slide

In the future..
  • Population growth and increase in prosperity 
  • 2050: 70% more food is needed
  • How can we do this without causing environmental degradation
Environmental degradation
Running out of natural resources by means of human use

Sustainable food production
Growing enough food without depleting the nature

Slide 12 - Slide

Sustainable food production
Producing food:

  • Without depleting the land
  • Without depleting natural resources

  • Without polluting the environment
  • Without environmental degradation 

Slide 13 - Slide

Four examples of dealing with food in a sustainable way
  1. Throw away less
  2. Save space by building food factories 
  3. Organic farming
  4. Genetic engineering

Slide 14 - Slide

1. Throw away less

Slide 15 - Slide

2: Food factories
  • Saving space
  • Better use of light
  • More efficient use of water
''Sla-flat''
Will your lettuce come from a ''sla-flat''?

Food factories
Saving space by building 
food factories

Slide 16 - Slide


3: Organic farming

  • Less or no pesticides
  • Less or no fertilizers 
  • The animals have more space

What is a disadvantage of organic farming?
Non-organic farming

Many animals per hectare
Poor living conditions for the animals
Organic farming

Fewer animals per hectare
Better living conditions for the animals

Slide 17 - Slide

Explain that to produce the same, more space is needed for organic farming than for large-scale farming.

Intensification
Dit vind ik zelf
het beste idee!
Good for the animals
Very big companies that produce that cultivates one kind of product

Slide 19 - Drag question

4. Genetic engineering
Modifying crops so that they can cope better with drought and diseases
