Full Prompt (IELTS Writing Task 2 - Problem/Solution)

Many people believe that streaming services are a significant cause of environmental pollution. What are the reasons for this belief? How can this problem be solved?

Four Authentic Model Answers (Bands 6-9)

Band 6.0 Answer

The problem of streaming services and pollution is serious. First, streaming needs lots of energy. Data centers use much electricity and produce carbon dioxide. Second, people use devices like phones and laptops that need charging, which creates more pollution. To solve this, companies should use renewable energy for data centers. Governments can make laws to reduce pollution from technology. Also, people should turn off devices when not in use.

Scoring Breakdown:

• Task Response (TR) 5.0: Presents a problem and some relevant solutions but lacks depth and specific examples.
• Coherence and Cohesion (CC) 6.0: Ideas are logically organized but with some repetition and limited connecting phrases.
• Lexical Resource (LR) 6.0: Uses some appropriate vocabulary but with frequent basic word choices and occasional errors.
• Grammatical Range and Accuracy (GRA) 6.0: Forms simple sentences correctly but makes frequent errors in complex structures.

Band 7.0 Answer

Streaming services contribute significantly to environmental degradation through two main mechanisms. Firstly, the data centers that store and transmit streaming content consume vast amounts of electricity, often generated from fossil fuels, thereby releasing substantial greenhouse gas emissions. Secondly, the production and disposal of electronic devices used for streaming generate electronic waste, which contains toxic substances harmful to the environment. To mitigate these issues, several strategies could be implemented. Streaming companies could invest in renewable energy sources for their data centers, reducing their carbon footprint. Governments might introduce regulations to improve the energy efficiency of electronic devices and promote recycling programs for e-waste. Additionally, consumers can adopt more sustainable habits, such as reducing streaming quality when possible and properly recycling old devices.

Scoring Breakdown:

• Task Response (TR) 7.0: Presents a clear problem-solution format with extended ideas and some examples.
• Coherence and Cohesion (CC) 7.0: Logically organizes information with clear connecting phrases and paragraphing.
• Lexical Resource (LR) 7.0: Uses a mix of appropriate vocabulary with some less common lexical items and occasional errors.
• Grammatical Range and Accuracy (GRA) 7.0: Forms a mix of simple and complex sentence structures with some errors.

Band 8.0 Answer

The rapid proliferation of streaming services has exacerbated environmental concerns, primarily through energy consumption and electronic waste. Data centers, which form the backbone of streaming infrastructure, demand enormous amounts of electricity, often derived from non-renewable sources, thereby escalating carbon emissions. Additionally, the constant upgrade cycle of electronic devices leads to a surge in e-waste, which poses significant environmental and health risks due to toxic materials. To address these challenges, a multi-faceted approach is essential. Streaming platforms should prioritize the construction of green data centers powered by renewable energy. Governments could enforce stricter regulations on energy efficiency standards for electronic devices and promote extensive e-waste recycling initiatives. Furthermore, educational campaigns could raise awareness among consumers about the environmental impact of their streaming habits and encourage more sustainable practices, such as optimizing streaming settings and extending the lifespan of electronic devices through proper maintenance and repair.

Scoring Breakdown:

• Task Response (TR) 8.0: Presents a clear position throughout with fully extended and supported ideas and examples.
• Coherence and Cohesion (CC) 8.0: Uses a clear progression of ideas with a wide range of cohesive devices.
• Lexical Resource (LR) 8.0: Uses a wide range of vocabulary with some less common and idiomatic expressions and occasional errors.
• Grammatical Range and Accuracy (GRA) 8.0: Forms a mix of simple and complex sentence structures with infrequent errors.

Band 9.0 Answer

The digital revolution has brought streaming services to the forefront of modern entertainment, yet this convenience comes with a substantial environmental cost that warrants urgent attention. The primary environmental concerns stem from the energy-intensive nature of data centers and the proliferation of electronic waste. Data centers, which host and deliver streaming content, account for approximately 1% of global electricity consumption, predominantly sourced from fossil fuels, thereby contributing significantly to carbon emissions. Concurrently, the short lifespan of electronic devices exacerbates the e-waste crisis, with toxic substances leaching into the environment and posing serious health risks. To ameliorate these issues, a concerted effort from all stakeholders is imperative. Streaming companies must transition towards renewable energy sources and invest in energy-efficient technologies for their data centers. Governments should enact and enforce stringent regulations on energy efficiency and e-waste management, coupled with incentives for recycling and proper disposal. Moreover, consumers must be educated about the environmental ramifications of their streaming habits and encouraged to adopt sustainable practices, such as reducing streaming quality, repairing devices, and participating in recycling programs. By fostering a collaborative approach, the environmental impact of streaming services can be mitigated, ensuring that technological advancements align with ecological sustainability.

Scoring Breakdown:

• Task Response (TR) 9.0: Presents a clear position throughout with fully extended and supported ideas and examples.
• Coherence and Cohesion (CC) 9.0: Uses a clear progression of ideas with a wide range of cohesive devices and paragraphing.
• Lexical Resource (LR) 9.0: Uses a wide range of vocabulary with full flexibility and precision, including less common and idiomatic expressions.
• Grammatical Range and Accuracy (GRA) 9.0: Forms a mix of simple and complex sentence structures with rare errors.
