Why are natural resources unevenly distributed globally?
Natural resources are spread unevenly, leading to wealth disparities and potential conflicts between countries.
What methods can be used to address water stress?
Methods include catching water, reducing waste (e.g., drip irrigation), recycling water, moving water via canals, and desalination.
Name some solutions to improve food security.
Building greenhouses, using hydroponics powered by renewable energy, and developing cultured meat.
What defines food security?
Food security means having access to enough safe and nutritious food for a healthy life at all times.
How has globalization accelerated?
Globalization has accelerated through containerization, information technology, air travel, and the rise of TNCs.
What is a natural resource?
A natural resource is something that occurs naturally without human help.
How does technology play in employment patterns?
They influence employment by increasing efficiency in work. By using a machine that takes a day to complete compared to humans which take weeks.
How does nature convert salt water into fresh water?
Nature converts salt water into fresh water through evaporation.
What is de-industrialisation?
De-industrialisation is the decline of traditional manufacturing industries.
How does population growth threaten food security?
Population growth increases demand for diverse foods, leading to higher competition and potential shortages.
What is overcultivation and its impact?
Overcultivation is unsustainable farming that depletes soil nutrients and degrades soil health.
What are transnational corporations (TNCs)?

What are reservoirs and aquifers?
Reservoirs are artificial or natural lakes fed by rivers, while aquifers are permeable rock formations that store and transmit groundwater.
What distinguishes renewable resources from non-renewable resources?
Renewable resources can be used sustainably without running out, while non-renewable resources have a finite supply that can be depleted.
What are the primary, secondary, tertiary, and quaternary economic sectors?
Primary involves producing raw materials; secondary involves manufacturing; tertiary provides services; quaternary involves high-level problem solving and innovation.
What is fossil water?
Fossil water is ancient water stored in aquifers for millennia, which is not a permanent resource.
What impact does climate change have on food security?
Climate change causes heatwaves, floods, pests, and diseases, which threaten crops and livestock, reducing food supply.
