Slide 4 - Diapositive
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 - Diapositive
Tropical rainforest and agriculture: Amazon
Slide 6 - Diapositive
Explain the difference between large-scale farming and intensification
Slide 7 - Question ouverte
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.
