Question 1: Define the term 'sustainability' in the context of food production and consumption.

Answer: Sustainability in food refers to producing and consuming food in ways that meet current needs without compromising the ability of future generations to meet theirs, by considering environmental, social, and economic factors.

Question 2: List three environmental benefits of choosing locally sourced food over imported food.

Answer: Reduces carbon emissions from transportation, supports local ecosystems and biodiversity, and encourages sustainable farming practices in the community.

Question 3: Explain why plant-based diets are generally considered more sustainable than diets high in animal products.

Answer: Plant-based diets typically require fewer natural resources such as water and land, produce lower greenhouse gas emissions, and are more efficient in converting energy from the environment into food for human consumption.

Question 4: Describe two ways in which food packaging can impact sustainability.

Answer: Packaging can contribute to waste and pollution if non-recyclable or excessive; sustainable packaging uses recyclable or biodegradable materials to reduce environmental impact.

Question 5: Identify three food choices you can make to reduce your carbon footprint.

Answer: Choosing plant-based meals, buying seasonal and local produce, reducing food waste by planning portions and storing food properly.

Question 6: Sketch a simple diagram to show a sustainable food chain, starting from farming to consumer, including at least three stages.

Answer: A correct sketch would depict a farm (illustrated with crops or animals), a transportation stage, and a marketplace or store, with arrows indicating the flow of food from production to consumption.

Question 7: Explain how reducing food waste contributes to sustainability.

Answer: Reducing food waste minimizes the resources used in food production, such as water, energy, and land, and decreases the amount of waste sent to landfills, which reduces methane emissions.

Question 8: Suggest one policy or initiative that could promote sustainable eating habits among teenagers.

Answer: Implementing school programs that educate students about sustainable food choices and providing access to locally sourced, healthy meals in school canteens.

Question 9: Describe how choosing organic foods can impact sustainability positively and negatively.

Answer: Positively, organic farming reduces chemical use and promotes biodiversity; negatively, organic foods can sometimes require more land and resources for the same yield, and may be more expensive, affecting accessibility.

Question 10: Identify two social factors that influence sustainable food choices.

Answer: Cultural food preferences and awareness or education about sustainability issues.
