Question 1: Define what is meant by the term 'sustainable food'.

Answer: Sustainable food refers to food produced in a way that meets current needs without compromising the ability of future generations to meet theirs, often involving environmentally friendly practices.

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

Answer: Reduced carbon footprint due to lower transportation emissions, preservation of local ecosystems, and support for local farmers.

Question 3: Explain why reducing meat consumption can contribute to sustainability.

Answer: Reducing meat consumption decreases greenhouse gas emissions, conserves water and land resources, and reduces environmental degradation associated with intensive livestock farming.

Question 4: Identify two challenges associated with increasing the consumption of plant-based proteins.

Answer: Limited availability or variety of plant-based options and potential cultural or personal preferences for meat-based diets.

Question 5: Describe how food packaging impacts sustainability and suggest one way to reduce this impact.

Answer: Food packaging contributes to waste and pollution; reducing impact can be achieved by using biodegradable packaging or encouraging reusable containers.

Question 6: Sketch a simple diagram illustrating a sustainable food chain from farm to table. Include at least three stages and label them.

Answer: A correct sketch would show stages such as 'Farm', 'Transport/Distribution', and 'Consumer/Market', with arrows indicating flow from production to consumption.

Question 7: Discuss the importance of seasonality in choosing sustainable foods.

Answer: Eating seasonal foods reduces the environmental impact by minimizing the need for artificial heating, cooling, or storage, and often supports local agriculture.

Question 8: Identify two ways consumers can make more sustainable food choices in everyday life.

Answer: Buying local and seasonal produce and reducing food waste by planning meals and storing food properly.

Question 9: Explain what is meant by a 'food mile' and how it relates to sustainability.

Answer: 'Food mile' refers to the distance food travels from production to consumer; shorter food miles generally mean lower carbon emissions and greater sustainability.

Question 10: Suggest one policy or initiative that governments could implement to promote sustainable eating habits among the population.

Answer: Implementing subsidies for local farmers or educational campaigns about sustainable food choices.

Question 11: Describe the potential impact on the environment if the global population shifts towards plant-based diets.

Answer: A significant reduction in greenhouse gas emissions, decreased land and water use, and less deforestation, leading to a healthier planet.
