§4.2: The world of food

Today

• Recap previous lesson


• Explanation §4.2
• Assingments

The space that is needed to produce the food for a single person

1. Ecological footprint
2. Food footprint
3. Carrying capacity
4. Footprint

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 

Tropical rainforest and agriculture: Amazon 

Explain the difference between large-scale farming and intensification

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.

Learning goals

• You know how you can produce more sustainable food.
• You understand why more and more space is needed to grow food and in what ways we can deal with food in a more sustainable way.

Vocabulary 

Environmental degradation	Milieu-uitputting
Dispose	Weggooien
Fertilizer	Kunstmest
Pesticides	Bestrijdingsmiddelen
To combat	Ter bestrijding van
Organic farming	Biologische landbouw
Genetic engineering	Genetische modificatie
Depleting	Uitputten
Cultivate	Verbouwen

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

Sustainable food production

Producing food:

• Without depleting the land
• Without depleting natural resources


• Without polluting the environment
• Without environmental degradation 

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
   

1. Throw away less

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

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

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

4. Genetic engineering

Modifying crops so that they can cope better with drought and diseases

Learning goals

• You know how you can produce more sustainable food.
• You understand why more and more space is needed to grow food and in what ways we can deal with food in a more sustainable way.
