International Green Warrior Olympiad Class 9 Sample Paper

Q.1

Imagine you're a development consultant working with a government agency in a developing country concerned about the high levels of post-harvest food losses. You're tasked with recommending the most impactful intervention based on the data provided in the graph below.

Which intervention would likely yield the greatest reductions in overall food losses while maximising impact across multiple commodities?

Q.2

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.3

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.

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.4

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.

Q.5

Blair, an environmentally conscious consumer, is shopping for groceries at a local store. She notices a food product with an eco-label that states "Organic" on the packaging. Curious about its meaning, she checks the information available to understand the significance of the label.

In the context of eco-labelling, what does the presence of an "Organic" label on a food product signify based on Emily's observation?

Q.6

You and your friends enjoy a delicious pizza lunch, packed with toppings like pepperoni, cheese, and pineapple. Later, while scrolling through social media, you come across a post highlighting the environmental impact of meat production. This sparks a conversation about your food choices and how they might affect the planet.
Considering the environmental footprints of your pizza toppings, which topping likely had the highest emissions associated with its production?

1. Pepperoni
2. Cheese
3. Pineapple

Q.7

An evaluation was conducted on the environmental impact of four different gaming consoles used extensively by a group of gamers. The details about consoles are provided in the table below.
Based on the information, which gaming console is likely to have caused the least environmental impact during the assessment period?

Q.8

Which innovative water purification method uses a combination of biological processes involving microorganisms to break down organic matter and remove contaminants from wastewater?

Q.9

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.10

An individual is trying to reduce their carbon footprint through their diet. Which action would have the most significant impact on reducing carbon emissions?
