3. “Ocean pollution is a serious environmental problem. What are the main causes and what measures could be taken to prevent it?” (Reported: June 2023, January 2022)

Question & Analysis

Plastic pollution is causing serious damage to our oceans and marine life. What are the main causes of this problem, and what measures can governments and individuals take to address it?

Give reasons for your answer and include any relevant examples from your own knowledge or experience.

Write at least 250 words.

Question Type: This is a two-part problem-solution question, specifically asking candidates to:

1. Identify and explain the main causes of ocean plastic pollution
2. Propose solutions from both governmental and individual perspectives

Key Terms to Understand:

• “Serious damage” – requires acknowledgment of severity, not just minor inconvenience
• “Marine life” – focus extends beyond aesthetics to biological impact
• “Governments and individuals” – both actors must be addressed; discussing only one weakens Task Response

Common Pitfalls:

• Writing only about causes without adequate solution discussion (or vice versa)
• Providing generic environmental solutions not specific to plastic pollution
• Focusing exclusively on government or individual action
• Using overly simplistic cause-effect relationships without depth

Strategic Approach:

1. Introduction: Paraphrase question + thesis statement outlining 2-3 main causes and solution types
2. Body Paragraph 1: Discuss 2-3 primary causes with specific examples
3. Body Paragraph 2: Present governmental solutions with practical examples
4. Body Paragraph 3 (or combined with Para 2): Present individual solutions
5. Conclusion: Summarize main points + final thought on collective responsibility

The proliferation of plastic waste in marine environments has emerged as one of the most pressing ecological challenges of our time, threatening both biodiversity and human health. This essay will examine the root causes of oceanic plastic pollution before proposing viable solutions at both governmental and individual levels.

The principal driver of marine plastic contamination stems from inadequate waste management infrastructure, particularly in rapidly developing nations where economic growth has outpaced environmental regulation. Coastal communities in Southeast Asia, for instance, often lack systematic collection systems, resulting in an estimated 8 million tonnes of plastic entering oceans annually. Compounding this issue is the pervasiveness of single-use plastics in modern consumer culture, from beverage bottles to packaging materials, which are discarded after minimal use. Furthermore, the inherent durability of plastic means that these materials persist in marine ecosystems for centuries, fragmenting into microplastics that enter the food chain and bioaccumulate in marine organisms.

Addressing this crisis requires multi-faceted intervention from policymakers and citizens alike. Governments should prioritize investment in comprehensive waste collection and recycling infrastructure, particularly in vulnerable coastal regions, while simultaneously implementing regulatory measures such as extended producer responsibility schemes that hold manufacturers accountable for the entire lifecycle of their products. The European Union’s ban on certain single-use plastics exemplifies how legislative action can drive meaningful change. Equally crucial is the role of individuals in cultivating sustainable consumption habits—opting for reusable alternatives, participating in community clean-up initiatives, and making purchasing decisions that favor environmentally responsible companies.

In conclusion, while oceanic plastic pollution originates from systemic failures in waste management and unsustainable consumption patterns, concerted efforts combining governmental regulation with grassroots behavioral change offer a viable pathway toward restoring marine ecosystem health. Only through such collective action can we hope to reverse the damage inflicted upon our oceans.

Plastic pollution in the oceans has become a major environmental problem in recent years, causing significant harm to marine animals and ecosystems. This essay will discuss the main reasons for this issue and suggest some practical solutions that both governments and individuals can implement.

There are several important causes of plastic pollution in our oceans. Firstly, many countries do not have proper waste disposal systems, especially in developing regions. When plastic waste is not collected or managed correctly, it often ends up in rivers and eventually flows into the sea. Secondly, the widespread use of single-use plastic products like bottles, bags, and straws contributes greatly to the problem. These items are used once and then thrown away, and because plastic takes hundreds of years to break down, it accumulates in the ocean. Another significant factor is that many people lack awareness about the environmental impact of their plastic consumption, so they continue using these products without considering the consequences.

To address this problem, governments need to take strong action. They should invest in better waste management infrastructure, particularly in coastal areas where waste is more likely to reach the ocean. Additionally, governments could introduce laws to ban or tax single-use plastics, which would encourage both manufacturers and consumers to find alternatives. For example, several countries have already banned plastic bags in supermarkets with positive results. Individuals also have an important role to play. People can reduce their plastic use by carrying reusable bags and water bottles, and they can participate in beach clean-up activities to remove existing pollution. Education is also crucial—if more people understand the serious effects of plastic pollution, they are more likely to change their behavior.

In conclusion, ocean plastic pollution results mainly from poor waste management and excessive use of disposable plastic products. However, through combined efforts of government regulation and individual responsibility, we can significantly reduce this environmental threat and protect marine life for future generations.

Nowadays, plastic pollution is a very big problem for the oceans and it is affecting many sea animals. In this essay, I will explain why this problem happen and what we can do to solve it.

There are many reasons why plastic pollution in ocean is increasing. First reason is people throw their plastic rubbish everywhere and it go to the sea. Many people use plastic bags and bottles everyday, and after they use it, they just throw away. This plastics go to rivers and then go to ocean. Also, some countries doesn’t have good system for collecting garbage, so plastic waste are not managed properly. Another problem is factories and companies make too much plastic products because it is cheap and easy to make. People also don’t know how bad plastic pollution is, so they keep using plastic without thinking about environment.

To solving this problem, governments and people must work together. Government should make rules to stop companies from making so much plastic, and they should also make more recycling center where people can bring their plastic waste. Some countries already ban plastic bags in shops, and this is good idea that other countries can copy. For individuals, we can use less plastic in our daily life. For example, we can bring our own shopping bags when we go to supermarket instead of using plastic bags. We can also use glass or metal bottle for water instead of plastic bottles. If everyone do these small things, it will make big difference.

In conclusion, plastic pollution in oceans happen because people use too much plastic and there is not good waste management. But if governments make good laws and people change their habits, we can reduce this problem and make ocean more clean for sea animals and future.

Learning from Mistakes

Mistake	Error Type	Correction	Explanation
“why this problem happen”	Subject-verb agreement	“why this problem happens”	Third person singular requires ‘-s’ in present simple. With question word order in noun clause, subject comes before verb.
“First reason is people throw”	Missing article + incomplete structure	“The first reason is that people throw”	Need definite article with superlatives/ordinals. Requires ‘that’ clause or different structure: “First, people throw…”
“This plastics go to rivers”	Demonstrative-noun disagreement + verb error	“These plastics go to rivers” / “This plastic goes to rivers”	‘This’ with singular noun, ‘these’ with plural. Verb must agree with subject number.
“some countries doesn’t have”	Subject-verb agreement	“some countries don’t have”	Plural subject requires plural verb form. “Doesn’t” only with singular third person subjects.
“To solving”	Infinitive form error	“To solve”	After ‘to’ expressing purpose, use base form of verb, not gerund (-ing form).
“make more recycling center”	Article + plural error	“build more recycling centers”	Countable plural nouns need plural form. “Make” less appropriate than “build/establish” for facilities.
“glass or metal bottle”	Singular/plural inconsistency	“glass or metal bottles” / “a glass or metal bottle”	After ‘use’ referring to general category, use plural or article + singular.
“If everyone do”	Subject-verb agreement	“If everyone does”	‘Everyone’ is singular, requiring singular verb form despite meaning ‘all people’.
“there is not good waste management”	Awkward negation	“there is no good waste management” / “waste management is inadequate”	Native speakers prefer “no” over “not…good” or use more precise vocabulary.
“make ocean more clean”	Word order + article	“make the ocean cleaner” / “make oceans cleaner”	Need article with ‘the ocean’ (specific) or plural ‘oceans’. Comparative form better than ‘more + adjective’ here.

High-Scoring Sentence Structures

1. Complex Subordination with Participle Phrases

Formula: Main clause + , participle phrase (providing additional information)

Example from Band 8-9 essay:
“Coastal communities in Southeast Asia often lack systematic collection systems, resulting in an estimated 8 million tonnes of plastic entering oceans annually.”

Why it scores well: This structure demonstrates sophisticated grammar by efficiently combining cause and effect in one sentence. The participle phrase adds detailed explanation without creating a separate sentence, showing advanced sentence management.

Additional examples:

• “Many marine species mistake plastic for food, causing internal injuries and often leading to starvation.”
• “Governments can implement tax incentives for biodegradable packaging, thereby encouraging innovation in sustainable materials.”
• “Ocean currents concentrate plastic debris in specific zones, creating massive garbage patches visible from space.”

Common mistakes to avoid:

• ❌ “Coastal communities lack collection systems, resulted in pollution.” (Wrong form: should be ‘resulting’)
• ❌ “They throw plastic away, which resulting in ocean pollution.” (Mixing relative clause with participle)
• ❌ “Resulting in pollution, coastal communities lack systems.” (Illogical order: cause must come before result)

---

2. Non-Defining Relative Clauses

Formula: Subject + , which/who [adds extra information about entire previous clause], + verb

Example from Band 8-9 essay:
“These materials persist in marine ecosystems for centuries, fragmenting into microplastics that enter the food chain and bioaccumulate in marine organisms, which poses serious health risks to humans.”

Why it scores well: Non-defining relative clauses add sophisticated commentary or consequence without interrupting the main statement flow. The comma usage demonstrates grammatical precision, and ‘which’ referring to an entire previous idea shows advanced referencing.

Additional examples:

• “Single-use plastics account for nearly 50% of ocean pollution, which suggests that banning them could have significant positive effects.”
• “The Great Pacific Garbage Patch spans an area twice the size of Texas, which illustrates the unprecedented scale of this environmental crisis.”
• “Many developing nations lack funding for advanced recycling facilities, which explains why plastic waste management remains inadequate in these regions.”

Common mistakes to avoid:

• ❌ “Plastic pollutes oceans that is a serious problem.” (Use ‘which’ for non-defining clauses, not ‘that’)
• ❌ “Plastic persists for centuries which poses risks.” (Missing comma before ‘which’)
• ❌ “The problem is serious, what requires urgent action.” (Use ‘which,’ not ‘what’)

---

3. Cleft Sentences for Emphasis

Formula: It is [noun phrase] that + clause OR What [subject + verb] is + noun phrase

Example from Band 8-9 essay:
“Only through such collective action can we hope to reverse the damage inflicted upon our oceans.”

Why it scores well: Cleft sentences emphasize particular information, demonstrating sophisticated discourse management. They show the writer can manipulate sentence structure for rhetorical effect rather than just presenting information straightforwardly.

Additional examples:

• “It is inadequate waste infrastructure that constitutes the primary cause of marine plastic pollution.”
• “What governments need to prioritize is investment in comprehensive recycling systems.”
• “It is through behavioral change at the individual level that lasting solutions will emerge.”
• “What makes this problem particularly challenging is the persistent nature of plastic materials.”

Common mistakes to avoid:

• ❌ “It is waste management that are the main problem.” (Subject-verb disagreement)
• ❌ “What we need is to build recycling systems.” (Awkward infinitive; prefer noun: “What we need is comprehensive recycling systems”)
• ❌ “That makes the problem serious is plastic durability.” (Use ‘What,’ not ‘That’)

---

4. Advanced Conditional Structures

Formula: Were [subject] to [base verb], + would/could + verb OR Should [subject] [base verb], + clause

Example adapted to topic:
“Were governments to implement comprehensive producer responsibility schemes, manufacturers would bear the full environmental costs of their products.”

Why it scores well: Inverted conditionals (without ‘if’) demonstrate mastery of complex grammatical forms. They’re formal and sophisticated, appropriate for academic writing, and show the writer can vary conditional structures beyond basic patterns.

Additional examples:

• “Should plastic production continue at current rates, ocean plastic may outweigh fish by 2050.”
• “Had stricter regulations been implemented decades ago, marine ecosystems would not face the current crisis.”
• “Were individuals to adopt reusable alternatives consistently, demand for single-use plastics could decrease by 60%.”

Common mistakes to avoid:

• ❌ “Were governments would implement policies…” (Remove ‘would’ from condition clause)
• ❌ “Should governments would ban plastics…” (Don’t use ‘would’ after ‘should’ in inverted conditional)
• ❌ “Were to governments implement…” (Wrong word order: ‘Were governments to’)

---

5. Fronted Adverbials with Inversion

Formula: Negative/restrictive adverbial + auxiliary verb + subject + main verb

Example from Band 8-9 essay:
“Only through such collective action can we hope to reverse the damage.”

Why it scores well: Inversion after negative or restrictive adverbials is a hallmark of sophisticated writing. It creates emphasis and demonstrates advanced control of word order rules, particularly important for Band 8-9 Grammatical Range.

Additional examples:

• “Never before has marine pollution reached such critical levels.”
• “Rarely do governments address the root causes of plastic pollution effectively.”
• “Not only does plastic harm marine life, but it also contaminates human food supplies.”
• “Under no circumstances should we underestimate the severity of ocean plastic pollution.”

Common mistakes to avoid:

• ❌ “Only then we can solve the problem.” (Missing auxiliary: “Only then can we”)
• ❌ “Never before plastic pollution has been so serious.” (Wrong order: “has plastic pollution been”)
• ❌ “Not only plastic harms wildlife…” (Missing auxiliary: “Not only does plastic harm”)

---

6. Complex Noun Phrases with Embedded Clauses

Formula: Noun + that/which clause + additional modification

Example from Band 8-9 essay:
“The inherent durability of plastic means that these materials persist in marine ecosystems for centuries, fragmenting into microplastics that enter the food chain.”

Why it scores well: Complex noun phrases pack multiple layers of information efficiently, showing ability to construct sophisticated academic structures. Embedding clauses within clauses demonstrates advanced sentence control.

Additional examples:

• “The legislation that the European Union implemented, which banned certain single-use plastics, has inspired similar policies globally.”
• “The microplastics that result from the breakdown of larger debris, which takes hundreds of years, now contaminate seafood consumed worldwide.”
• “The systemic failures in waste management infrastructure that characterize many developing nations require substantial international investment.”

Common mistakes to avoid:

• ❌ “The plastic what pollutes oceans is dangerous.” (Use ‘that/which,’ not ‘what’)
• ❌ “The problem that it affects marine life…” (Remove redundant ‘it’)
• ❌ Overloading: “The plastic that people use that comes from factories that produce too much…” (Simplify or break into multiple sentences)

Conclusion

Mastering IELTS Writing Task 2 questions about ocean plastic pollution requires understanding the clear distinctions between band levels: Band 8-9 essays demonstrate sophisticated vocabulary, complex grammatical structures, and nuanced idea development with specific examples; Band 6.5-7 essays show competent control with adequate range but less precision; and Band 5-6 essays address the task with relevant ideas but limited development and frequent errors.

The path to improvement involves systematic work across all assessment criteria. Focus on expanding your topic-specific vocabulary with precise collocations like “extended producer responsibility” and “bioaccumulate in marine organisms” rather than generic environmental terms. Develop your grammatical range by practicing structures such as participle phrases, cleft sentences, and inverted conditionals that naturally demonstrate complexity without sounding forced.

Your Action Plan:

1. Immediate practice: Write a response to one of the verified questions provided in this guide, timing yourself strictly at 40 minutes
2. Self-evaluate: Use the scoring tables and checklists to identify your current strengths and specific areas needing improvement
3. Targeted improvement: Choose 2-3 priority areas (e.g., grammatical accuracy, vocabulary range, idea development) and focus practice on these for two weeks
4. Regular writing: Commit to writing at least two complete Task 2 essays weekly, gradually increasing difficulty and time pressure

Realistic Timeline:

• 1 month: Noticeable improvement in one band descriptor (e.g., vocabulary or grammar)
• 2-3 months: Potential to move up 0.5-1.0 band overall with consistent, focused practice
• 3-6 months: Realistic timeframe for significant improvement (e.g., Band 6 to 7, or 7 to 8)

Remember that improvement is gradual and requires exposure to quality model essays, regular practice under timed conditions, and careful reflection on feedback. The sophisticated structures and vocabulary presented here should be internalized through repeated practice until they become natural parts of your writing repertoire.
