Urbanisation impact?
Habitat loss, replaced by cities
1 sustainable practice
Crop rotation, organic farming,
Largest biome on Earth?

Define irrigation
Artificial watering of crops
How climate affects food security
Droughts, floods, reduced yields
Land degradation?
Loss of land quality from overuse
How reducing food waste helps
More food available for people
Biome with permafrost
Tundra
Why cash crops in tropics?
Warm temperatures + high rainfall
Cause of food insecurity
Poverty, conflict, disasters, etc.
Overfishing impact?
Reduced fish populations, ecosystem imbalance
Role of technology
Improves yield (drones, sensors, etc.)
How does latitude affect biomes?
It changes temperature & rainfall from equator to poles
One impact of intensive farming
Soil degradation, pollution, habitat loss
Trade improving & harming food security
Access to diverse food but reliance on imports
One biome restoration method
Reforestation, sustainable farming,
How ecosystems support food
Provide pollination, soil & clean water
