International Green Warrior Olympiad Class 9 Sample Paper

Q.1

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.2

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?

In the case study, it is mentioned that coral reefs confront challenges from pollution and climate change. How do these challenges interact to negatively affect Raja Ampat's coral reefs?
1. Pollution weakens coral reefs, making them more susceptible to bleaching and mortality as ocean temperatures rise.
2. Climate change alters ocean currents, causing an increased accumulation of pollutants near reefs, adding to their stress.
3. Pollution can harm reefs, but it doesn't significantly affect their vulnerability to climate change impacts.

Q.4

You're at the supermarket deciding between locally-grown organic vegetables and conventionally-grown vegetables shipped from a distant country. Both cost the same. Considering climate change:

Q.5

A major Himalayan glacier, a vital source of freshwater for millions downstream, is retreating at an alarming rate. Satellite imagery reveals a significant decrease in the glacier's mass over the past few years. Data also shows a connection between rising global temperatures and the accelerated melting of glaciers worldwide.
Considering the scenario, which of the following is the most likely consequence of the glacier's retreat for the communities downstream?

Q.6

Satellites have documented the rapid retreat of glaciers in Antarctica and Greenland, contributing significantly to global sea level rise. In addition to coastal flooding, this melting ice could also:

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.8

A community experiences an outbreak of a waterborne disease called Amoebiasis, characterised by severe abdominal cramps, diarrhoea with blood, and high fever. Individuals affected report exposure to contaminated water sources. Identify the causative agent responsible for these symptoms.
