Q.1	Emma works at a fish farm that practices responsible aquaculture. She ensures the farm's operations prioritise environmental sustainability. What might be a typical aspect of responsible aquaculture that Emma would advocate for?
	a) Increasing the use of antibiotics to prevent fish diseases		b) Discharging excess fish feed directly into natural water bodies
	c) Implementing bioremediation techniques to naturally filter and clean the farm's water		d) Harvesting fish without considering breeding cycles

Q.2	A large oil spill from a tanker accident devastates a coastal ecosystem. Oil slicks coat beaches and contaminate the water, impacting birds, fish, and other wildlife. In addition to immediate cleanup efforts, what long-term environmental impacts should be monitored and addressed following this disaster? 1. The potential for oil residue to persist and enter the food chain 2. The disruption of coastal habitats and sensitive ecosystems 3. The economic and social impacts on fishing communities and tourism industries
	a) Only 1		b) Only 1 and 2
	c) Only 2 and 3		d) 1, 2 and 3

Q.3	You're a local community leader in a coastal village known for its thriving fish farms. While these farms provide valuable food and income for the community, you've noticed concerns about water quality, with algae blooms and fish kills in nearby rivers. Scientists attribute this to nutrient runoff from the farms. To promote responsible aquaculture and address these environmental concerns, which principle should be prioritised?
	a) Maximising fish production by increasing stocking density in existing ponds.		b) Expanding the aquaculture area by clearing mangroves.
	c) Investing in systems that recycle water and minimise waste discharge.		d) Providing subsidies to farmers who use traditional aquaculture methods.

Q.4	You are an environmental consultant advising a company on the selection of laptops for their office.
