Worksheet time: 19mins
What size are microplastics defined as?
Smaller than 10 millimeters
Smaller than 5 millimeters
Smaller than 1 millimeter
Smaller than 0.1 millimeters
What percentage of tap water samples worldwide contain microplastics?
50%
60%
70%
80%
Where have microplastics been found in the human body?
Bloodstream, lungs, and placentas
Liver, kidneys, and heart
Brain, muscles, and bones
Skin, hair, and nails
How much plastic does the average human consume weekly?
1 gram
3 grams
5 grams
7 grams
What are primary microplastics?
Plastics that are larger than 5 millimeters
Plastics that are manufactured small
Plastics that break down from larger waste
Plastics found in the ocean
Which country contributes over 35% of the plastic waste that leaks into the ocean?
Malaysia
Indonesia
Philippines
Thailand
What is the main source of inhaled microplastic fibers?
Industrial emissions
Household dust and clothing
Vehicle exhaust
Agricultural activities
What is the estimated amount of plastic waste produced by humans annually?
100 million tonnes
200 million tonnes
300 million tonnes
400 million tonnes
How do microplastics critically impact marine ecosystems?
They primarily affect the aesthetic value of marine environments.
Their impact on deep-sea ecosystems is negligible due to low concentrations.
They cause severe consequences for marine life.
They can increase the turbidity of the water, which benefits some filter feeders.
To what extent has the Basel Convention been effective in regulating plastic waste exports?
It has eliminated plastic waste exports.
It has made it harder for wealthier nations to export certain categories of plastic waste.
Its effectiveness is debated, with some evidence suggesting minimal impact due to non-compliance and the complexity of tracking plastic waste.
The overall volume of plastic waste generated globally has continued to rise, potentially offsetting some of its impact on export figures.
How do the contributions of primary and secondary microplastics in environmental pollution differ?
Primary microplastics are more harmful than secondary microplastics.
Secondary microplastics are manufactured small.
Both contribute significantly to environmental pollution.
Neither has a significant impact on pollution.
How are microplastic pollution and climate change linked?
Microplastic pollution has no connection to climate change.
Microplastic pollution exacerbates climate change.
Climate change reduces microplastic pollution.
Microplastic pollution mitigates climate change.
Could the UN Plastics Treaty significantly benefit the entire plastic lifecycle, from production to disposal?
No, it focuses heavily on plastic production.
Yes, it establishes action plans across all stages.
No, it ignores the plastic lifecycle.
Yes, it primarily targets plastic waste management.
How can microplastic pollution be reduced more effectively in Southeast Asia?
Primarily focus on large-scale ocean cleanup initiatives.
Improve waste management and recycling infrastructure tailored to each nation.
Advocate for the use of biodegradable plastics as a complete replacement for conventional plastics.
Implement advanced incineration technologies for all plastic waste.
How does public awareness function in the efforts to combat microplastic pollution?
Public awareness is important and sufficient in combatting microplastics pollution.
Public awareness is crucial for driving change by influencing consumer behavior, supporting policy changes, and holding corporation accountable.
Public awareness leads to feelings of helplessness or 'eco-anxiety' without providing clear actionable steps, potentially hindering engagement.
Public awareness is irrelevant to microplastic pollution.
What are the primary challenges hindering effective plastic waste management in Southeast Asia?
High recycling rates and efficient waste management systems
Low recycling rates and lack of access to formal waste services
Growing awareness in plastic pollution
Lack of policy and inconsistent enforcement
What is the primary factor to consider when evaluating the environmental impact of biodegradable plastics?
They decompose easily in any condition.
They require specific conditions to decompose.
They are cheaper to produce than regular plastics.
They have no impact on the environment.
Which statement best describes the current role of the informal waste sector in plastic waste management?
It plays no role in waste management in many regions.
It is highly efficient and consistent on the global scale.
It plays a major role in many developing economies but faces vulnerabilities and limitations.
It creates stability and predictability in recycling industries.
Which action plan effectively advocates for stricter microplastic regulations?
Primarily focus on individual consumer boycotts of products containing microplastics without engaging policymakers.
Support policies like microbead bans, extended producer responsibility schemes, and ambitious plastic reduction targets through public awareness campaigns and lobbying efforts.
Conduct more scientific research on the impacts of microplastics without actively translating findings into policy recommendations or public pressure.
Encourage voluntary commitments from industries to reduce microplastic leakage without legally binding regulations or enforcement mechanisms.
Based on the SustainEd lecture, what is the potential challenge in using alternative packaging materials to reduce plastic pollution?
They have a higher carbon footprint.
They are more cost-effective than plastic.
They lack potential to eliminate plastic pollution.
They are widely scalable and affordable.
