- False
Answer: True
When manufacturers maintain product ownership, they benefit from designing longer-lasting, repairable items and recovering materials at end-of-life, aligning economic and environmental goals.
The 'Right to Repair' movement advocates for policies that enable consumers to fix products, extending their lifespan and supporting _____ economy principles.
- Linear
- Circular

- Disposable
Answer: Circular
Right to Repair laws combat planned obsolescence, reduce e-waste, and empower consumers by ensuring access to parts, tools, and information for product maintenance.
Which of the following is a core principle of the 'Circular Economy' model?
- Take-Make-Dispose linear model
- Design out waste, keep products and materials in use, regenerate natural systems
- Maximize single-use products
- Focus only on end-of-pipe recycling
Answer: Design out waste, keep products and materials in use, regenerate natural systems
Circular economy shifts from linear consumption to closed-loop systems emphasizing durability, reuse, remanufacturing, and regenerative design to minimize resource extraction.
Which of the following best describes the 'Bystander Effect' in the context of environmental collective action?
- Individuals are more likely to act when they see others acting
- Individuals are less likely to take action when they assume others will address the problem
- Everyone acts immediately in environmental emergencies

Which of the following is a strategy to overcome the 'Intention-Action Gap' in pro-environmental behavior?
- Providing more information only
- Reducing friction - making sustainable actions convenient, affordable, and socially visible
- Ignoring behavioral barriers
- Relying solely on moral appeals
Answer: Reducing friction - making sustainable actions convenient, affordable, and socially visible
Bridging the gap between environmental concern and action requires addressing practical barriers like cost, convenience, and social norms alongside awareness.
The concept of 'Eco-anxiety' refers to chronic fear of environmental doom that can affect mental health, particularly among _____ who are more aware of climate risks.

- Corporate executives
- Retired individuals
Answer: Young people
Eco-anxiety, recognized by mental health professionals, reflects distress about climate change impacts on future generations, requiring supportive coping strategies and meaningful action.
The 'Tragedy of the Horizon' refers to the challenge that the worst impacts of climate change lie beyond typical decision-making timeframes, reducing urgency for action.
- True
- False
Answer: True
Coined by Mark Carney, this concept highlights how short-term political and business cycles conflict with the long-term nature of climate risks, hindering preventive action.
The 'Value-Belief-Norm' theory suggests that environmental action is motivated by personal values, awareness of consequences, and a sense of _____ responsibility.

Answer: Moral
This theory posits that altruistic and biospheric values, combined with awareness of environmental threats and personal responsibility, activate pro-environmental norms and behavior.
Which of the following is a barrier to pro-environmental behavior change according to behavioral science?
- Clear information and feedback
- Present bias - prioritizing immediate rewards over long-term environmental benefits
- Strong social norms supporting conservation
- Convenient access to recycling facilities
Answer: Present bias - prioritizing immediate rewards over long-term environmental benefits
Behavioral economics identifies cognitive biases like present bias, status quo bias, and lack of immediate feedback as obstacles to adopting sustainable behaviors.
Which of the following best describes 'Greenwashing' in the context of environmental marketing?
- Using eco-friendly packaging
- Making misleading claims about the environmental benefits of a product or practice
- Certifying products through legitimate eco-labels
- Investing in renewable energy
Answer: Making misleading claims about the environmental benefits of a product or practice
Greenwashing deceives consumers by overstating environmental credentials, undermining genuine sustainability efforts and eroding trust in green claims.
Which of the following is a potential impact of 'Space Debris' on the space environment?
- Improving satellite communication
- Risk of collision with operational satellites and spacecraft, creating more debris (Kessler Syndrome)
- Enhancing astronomical observations
- Reducing launch costs
Answer: Risk of collision with operational satellites and spacecraft, creating more debris (Kessler Syndrome)
Accumulated space junk poses collision risks that could trigger cascading debris generation, threatening space infrastructure and future space activities.
The phenomenon of 'Arctic Amplification' refers to the faster rate of warming in the _____ region compared to the global average.
- Antarctic
- Arctic
- Equatorial
- Tropical
Answer: Arctic
Arctic Amplification occurs due to feedbacks like sea ice loss reducing albedo, leading to accelerated warming with global implications for weather patterns and sea level rise.
Light pollution from urban areas can disrupt nocturnal wildlife behavior, bird migration, and human circadian rhythms.
- True
- False
Answer: True
Excessive artificial light at night interferes with natural light-dark cycles, affecting animal navigation, reproduction, and plant phenology, while also impacting human health.
The term 'Planetary Boundaries' refers to nine Earth system processes within which humanity can continue to develop and thrive for generations to come; one such boundary is climate change, another is _____.
- Stock market volatility
- Biodiversity loss
- Urbanization rate
- Internet usage
Answer: Biodiversity loss
The Planetary Boundaries framework identifies critical Earth system processes like climate change, biodiversity integrity, nitrogen/phosphorus cycles, and land-use change that must remain within safe limits.
Antimicrobial resistance (AMR) in the environment is exacerbated by the discharge of pharmaceutical waste and antibiotic use in agriculture.
- True
- False
Answer: True
Environmental contamination with antibiotics selects for resistant bacteria, which can transfer resistance genes to pathogens, posing a global public health threat.
