In this scenario, which of the following parameters would be of concern?

1. Turbidity
2. pH
3. Faecal coliform bacteria

Q.3

Your city is considering expanding its aquaculture industry to meet the growing demand for seafood. However, traditional aquaculture practices can contribute to water pollution and habitat degradation.
Which of the following approaches would be most sustainable for developing a responsible aquaculture industry?

Q.4

Wanda notices that even when her electronic devices are turned off, they still consume a small amount of energy in standby mode. This "phantom power drain" adds up over time, contributing to wasted energy and higher electricity bills.
What can Wanda do to reduce the phantom power drain in her home?

A. Unplug all her electronic devices when not in use.
B. Install smart power strips that automatically turn off unused devices.
C. Replace her old appliances with energy-efficient models.
D. Switch to a different electricity provider with lower rates.

Q.5

Dylan is considering buying a new smartphone. He knows that smartphones have a short lifespan and contribute to e-waste. He finds a company that offers a phone made with recycled materials and ethical sourcing practices.
Compared to a conventional phone, how would this choice impact Dylan's environmental footprint?

Q.6

Consider the case study given below and answer the following question:

Case Study: Protecting the Coral Reefs of Raja Ampat, Indonesia

Location: Raja Ampat, a stunning archipelago in Indonesia famed for its thriving coral reefs, biodiversity, and diving tourism.

Challenges:
-Overfishing: Unsustainable fishing practices, including blast fishing and cyanide fishing, have depleted fish stocks and damaged coral reefs.
-Pollution: Plastic pollution, agricultural runoff, and sedimentation from coastal development all threaten the delicate marine ecosystem.
-Climate Change: Rising ocean temperatures and acidification are bleaching and killing coral, the foundation of the reef ecosystem.

Initiatives:
-Marine Protected Areas (MPAs): Establishing and enforcing MPAs restricts harmful fishing practices and allows reefs to recover. Raja Ampat boasts one of the largest MPAs in Southeast Asia, covering over 1.5 million hectares.
-Community-Based Management: Local communities play a crucial role in protecting their reefs. The Coral Triangle Initiative focuses on empowering them through sustainable fishing practices and alternative livelihoods like ecotourism.
-Sustainable Aquaculture: Farming fish responsibly reduces pressure on wild stocks and provides alternative income for fishermen. Locally managed fish farms in Raja Ampat demonstrate successful alternatives to overfishing.
-Coral Restoration: Innovative techniques like coral nurseries and transplantation help regenerate damaged reefs and restore marine biodiversity.

Outcomes:
-Fish stocks are rebounding: The Raja Ampat MPA has shown a significant increase in fish biomass within its boundaries, demonstrating the effectiveness of protected areas.
-Improved water quality: Reduced pollution and sedimentation contribute to healthier corals and a more vibrant marine environment.
-Empowered communities: Local involvement in conservation fosters environmental stewardship and provides sustainable economic opportunities.

Raja Ampat serves as a beacon of hope in marine conservation, demonstrating the effectiveness of community-driven, multi-pronged approaches to protecting life below water. By tackling overfishing, pollution, and climate change, we can safeguard the future of these vital ecosystems and the communities that depend on them

What is a long-term challenge that the case study implies requires continuous global support to ensure the success of marine conservation in Raja Ampat?

Q.7

A family living in a region with abundant clean hydropower is considering replacing their ageing gas oven with a new electric model. However, they are concerned about the overall environmental impact of each option.

Analyse the following data table and choose the most likely outcome of switching to electric based on environmental considerations.

Q.8

The adverse environmental effects of burning fossil fuels extend beyond local air pollution.
Which of the following phenomena illustrates a global consequence of increased carbon emissions?

Q.9

By tackling overfishing, pollution, and climate change, we can safeguard the future of these vital ecosystems and the communities that depend on them.

A plastic net washes ashore on the Raja Ampat beach. Trace its potential journey through the marine ecosystem, describing the environmental and ecological consequences it could cause at each stage.

1. Entanglement for sea turtles, fish, and coral, leading to injuries and potential death.
2. Ingestion by marine life, mistaking it for food, causing blockages and internal damage.
3. Breakage into microplastics, accumulating in the food chain and harming higher predators.

Q.10

You are an environmental scientist analysing water quality parameters from two different sources, Source A and Source B. These sources provide water to nearby ecosystems. Consider the following data table showing water quality parameters from two different sources. Based on this data, which of the statements is most likely true?

1. Higher nutrient levels in Source A suggest an increased likelihood of eutrophication.
2. Source B has higher Dissolved Oxygen and Total Dissolved Solids (TDS) than Source A, implying better water quality for the nearby ecosystems.
3. Lower Dissolve Oxygen levels in Source A indicate the potential for oxygen depletion due to increased organic matter decomposition.
D. Hypoxic and alkaline conditions in Source B can lead to the formation of algal blooms.
