Q.8	Consider the case study given below and answer the following question: Case study: Combatting Global Food Waste In a study conducted by the World Resources Institute, it was estimated that one-third of all food produced globally is wasted. This staggering amount represents a significant loss of resources, including water, land, and energy, and contributes to greenhouse gas emissions. To address this pressing issue, researchers have developed various strategies to reduce food waste, each tailored to specific stages of the food supply chain. At the household level, meal planning and proper storage practices can significantly reduce food waste. Planning meals ahead of time helps individuals avoid impulse purchases and ensures that ingredients are used before they spoil. Proper storage, such as keeping fruits and vegetables in the refrigerator and storing pantry items in airtight containers, extends the shelf life of food. In the retail sector, implementing innovative technologies like dynamic pricing and smart packaging can help reduce food waste. Dynamic pricing adjusts the price of perishable items based on their freshness, encouraging consumers to purchase items before they spoil. Smart packaging incorporates sensors that monitor the freshness of food, alerting retailers when items are nearing their expiration dates. Food waste reduction strategies also extend to the production and processing stages of the food supply chain. Improved harvesting techniques and post-harvest handling practices can minimise damage to crops and reduce food losses. Additionally, diverting inedible food scraps from landfills to composting facilities can convert waste into valuable nutrient-rich soil amendments. By implementing these strategies at various stages of the food supply chain, we can collectively reduce food waste, conserve resources, and minimise our environmental impact. Based on the scenario provided, which statement best summarises the overall impact of the food waste reduction initiative? 1. Food waste reduction conserves resources and minimises environmental impact. 2. Food waste reduction improves food security and reduces hunger. 3. Food waste reduction promotes sustainable agriculture and economic growth.
	a) Only 1		b) Only 1 and 2
	c) Only 2 and 3		d) 1, 2 and 3

	a) While some plant-based proteins may be slightly less effective, they offer environmental benefits and can still support fitness goals.		b) Plant-based proteins are inferior to whey proteins in terms of muscle building and recovery.
	c) The environmental impact of protein powder is minimal compared to other food choices, so switching is unnecessary.		d) The protein source doesn't matter as long as the total protein intake is sufficient.
