Food Systems and Society

Having a food surplus meant that not everyone in a community had to farm to survive. This allowed individuals to specialize in other trades, such as pottery, toolmaking, weaving, and governance, leading to the development of complex societies.

FCR stands for Food (or Feed) Conversion Ratio, which measures how efficiently an animal converts feed into body mass. Option A correctly identifies this term, whereas 'ration' refers to the daily feed allowance itself.

Home-cooked diet formulations for pets should be re-evaluated and updated every 1 to 2 years to account for changes in the pet's age, weight, health status, and nutritional needs. This ensures the diet remains balanced and appropriate over time.

Supermarkets typically source food from global supply chains rather than local producers. Farm shops, farmer's markets, and local box schemes are specifically designed to sell locally grown produce.

Food waste is caused by a combination of improper storage, excessive portion sizes, and poor meal planning. All these factors contribute to the significant amount of food discarded by consumers.

Carbon emissions, food miles, and carbon footprint are all environmental metrics. Free range is an animal welfare standard, not an environmental impact metric.

People concerned about intensive farming practices like caged hens choose organic foods to support animal welfare. Organic standards require better living conditions for animals. Options A, C, and D are disadvantages or characteristics of organic food, not reasons people choose it. Option B, despite grammatical awkwardness, correctly identifies animal welfare concerns as a motivation for choosing organic.

Food provenance refers to the origin and source of food - where it comes from and how it reaches the consumer, including geographical origin, production methods, and supply chain. Option A describes organic food, option B describes intensive farming, and option D (poorly phrased) describes fair trade. Only option C correctly defines provenance as the origin and journey of food.

Global food consumption is uneven due to a combination of factors, including economic disparities, unequal distribution of resources, and the inability of some nations to produce or afford enough food for their populations.

Stabilizing the human population is widely considered the only long-term, sustainable solution to food supply issues, as it addresses the root cause of increasing demand. While increasing yields helps, it does not address the exponential growth of the population.

Decreasing the productivity of land would reduce the total food supply, which is the opposite of the goal to increase it. Strategies to increase supply include expanding land, improving technology, and increasing yields.

People in developing nations generally have lower caloric intake and rely more on plant-based diets compared to the high-meat, high-calorie diets common in developed nations.

Grain-fed beef production is less resource-efficient because it requires large quantities of grain to be grown, transported, and fed to cattle to produce a relatively small amount of meat, compared to direct human consumption of the grain.
