What percentage of deforested land is used for cattle ranching?

• 40

• 50

• 60

• 80

Choose a global effect of cattle ranching

• Methane is released, enhancing the greenhouse effect

• Carbon dioxide is released, enhancing the greenhouse effect

• Nitrous oxides are released, enhancing the greenhouse effect

• Habitat loss reduces biodiversity

What are dead zones?

• Oceans with low biodiversity due to fertiliser run off

• Oceans with high biodiversity due to fertiliser run off

• Areas of extreme high deforestation

• Areas of low biodiversity due to greenhouse gas emissions

Choose two local effects of using artificial fertilisers

• Loss of income for fishermen

• Nitrous oxides are released, enhancing the greenhouse effect

• Habitats are destroyed

• CO2 is released, enhancing the greenhouse effect

Food miles measure...

• The amount of greenhouse gas emissions released

• The area of land deforested to grow food

• The distance from where a food is produced and where it is eaten

Choose a global effect of high food miles

• Methane is released, enhancing the greenhouse effect

• Carbon dioxide is released, enhancing the greenhouse effect

• Nitrous oxides are released, enhancing the greenhouse effect

• Habitat loss reduces biodiversity
