Sustainable Development — 2nd-Year Baccalaureate English Thematic Unit
1. Introduction to the Theme
Sustainable development is one of the defining challenges of our time. At its core, it is defined as meeting the needs of the present without compromising the ability of future generations to meet their own needs. This simple definition carries enormous implications: every economic decision, every policy choice, and every individual habit either brings us closer to, or further from, a livable planet for those who come after us.
The theme rests on three foundational pillars: economic growth, environmental protection, and social equity. None of these can be pursued in isolation. A country that grows its economy by destroying its forests or polluting its rivers is not developing sustainably; it is borrowing against a debt that future generations will be forced to repay. Equally, environmental policies that ignore poverty and inequality cannot build the broad social support they need to succeed.
At the international level, the United Nations Sustainable Development Goals (SDGs) provide a shared framework of targets that countries around the world have committed to achieving. Studying this theme in English therefore connects you to a global conversation — one in which Morocco is an active participant. The country's Noor solar power project in Ouarzazate, widely recognised as the world's largest solar facility, is a concrete local example that illustrates how a developing nation can lead on renewable energy. This unit will help you engage with these ideas critically, express them accurately, and perform confidently in the national Baccalaureate examination.

4. Discussion and Reading-Comprehension Angles Likely at the Bac
Baccalaureate reading texts on this theme typically include news articles, policy summaries, research overviews, and case studies. The questions test a range of skills: literal comprehension (what the text explicitly states), inference (what can be deduced from implicit cues), vocabulary in context, and the ability to identify cause-and-effect relationships and main ideas.
Common Discussion Questions
- How do solar, wind, and hydroelectric energy compare in terms of effectiveness and environmental impact?
- Why is Morocco's geographic location particularly well suited to solar energy development?
- What economic and social benefits can large-scale renewable energy projects bring to local communities?
- What barriers prevent developing nations from fully transitioning to green energy?
- How does individual consumer behaviour — such as fair-trade purchasing or recycling — influence broader sustainability outcomes?
- What role does international cooperation play in helping countries achieve the UN Sustainable Development Goals?
- How can communities balance the demands of economic growth with the need to protect natural ecosystems?
- In what ways are poverty, education, and sustainable development interconnected?
Debate Strategy
When a discussion question is open-ended, always structure your answer to acknowledge both sides before stating your position. Use the debate frame: "On one hand, [argument]. On the other hand, [counterargument]. However, I believe... because..." This signals critical thinking to the examiner and earns higher marks for organisation.
5. Writing and Production Tips
Essay Structure at a Glance
Introduction (50–60 words): Open with a clear definition or a thought-provoking observation. Briefly mention the scale of the issue. Close the introduction with a thesis sentence that signals your argument. Example: "Sustainable development — meeting present needs without sacrificing the future — has become an urgent global priority as environmental pressures intensify."
Body Paragraph 1 (100–150 words): Define sustainable development and explain why all three pillars (economic, environmental, social) must work together. Use a topic sentence, explanation, and a linking sentence to your next paragraph.
Body Paragraph 2 (100–150 words): Present concrete evidence. Discuss renewable energy projects, conservation achievements, or policy initiatives. Specific, well-chosen examples are far more persuasive than vague generalisations.
Body Paragraph 3 (100–150 words): Address challenges or counterarguments — for example, the high upfront costs of green technology or the difficulties developing nations face when transitioning away from fossil fuels. Acknowledging complexity strengthens rather than weakens your essay.
Conclusion (30–40 words): Summarise your key points in two or three sentences. End on a forward-looking note: "With sufficient political will and sustained international cooperation, sustainable development is not merely an aspiration — it is an achievable goal."
Vocabulary and Grammar Tips for the Writing Section
- Avoid repetition by using synonyms: sustainability / ecological responsibility; development / progress; environment / natural world.
- Use authentic collocations: achieve targets, implement solutions, reduce carbon emissions, phase out fossil fuels, invest in green technology.
- Show word-formation mastery. Rather than writing "sustainable" repeatedly, vary with: sustainability, sustainably, sustain.
- Use modal verbs purposefully: must / have to for necessity; should / ought to for advice; can / might for possibility.
- Apply future tenses correctly. Time markers are your guide: "by 2030" signals future perfect (will have + past participle); "this time next year" signals future continuous (will be + -ing).
- Maintain a consistent formal register throughout — avoid contractions and informal expressions.
Common Pitfalls to Avoid
- Oversimplifying complex trade-offs — always acknowledge that solutions come with challenges.
- Making claims without supporting evidence — back every assertion with a fact, statistic, or example.
- Mixing formal and informal registers in the same piece — choose one and stay consistent.
- Using vague pronouns ("they," "it") without clear antecedents — always specify your subject.
6. Grammar Focus: Future Tenses and Modal Verbs
Future tenses and modal verbs are tested directly in the Language section of the Baccalaureate. They are also indispensable tools for discussing sustainability scenarios, predictions, and obligations. Study the three main future forms and the most important modals.
Future Tenses
- Simple Future (will + base verb) — predictions and deliberate decisions. Example: "Morocco will meet its renewable energy targets by 2030."
- Future Continuous (will be + -ing) — an action in progress at a specific future moment. Triggered by phrases such as "this time next year." Example: "This time next year, the facility will be supplying electricity to hundreds of thousands of homes."
- Future Perfect (will have + past participle) — completion before a future point. Triggered by "by [time]." Example: "By 2030, the country will have completed its transition to clean energy."
Modal Verbs
- Must / Have to — strong necessity. "We must protect endangered habitats." Mustn't = prohibition: "You mustn't dump toxic waste in rivers."
- Should / Ought to — advice or recommendation. "Governments should invest in clean technology."
- Can / Could — ability or possibility. "Solar panels can generate clean electricity even in cloudy conditions."
- May / Might — uncertainty or weaker possibility. "Climate change might cause more frequent and intense droughts in semi-arid regions."
💡
Exam Strategy: Before selecting a future tense or modal verb, underline all time markers and context clues in the sentence. "By 2035" → future perfect. "This time next decade" → future continuous. "We urgently need to act" → must or have to. This simple habit prevents the most common grammar errors under exam pressure.
7. Word Formation and Exam Language Exercises
The Language section of the Bac regularly tests your ability to transform base words into the correct grammatical form. The golden rule is: identify the grammatical slot first (do you need a noun, verb, adjective, or adverb?), then apply the appropriate suffix or prefix.
Key Suffix Patterns
- -ity: sustain → sustainability; diverse → diversity; equal → equality
- -ment: develop → development; improve → improvement
- -al: environment → environmental; industry → industrial; tradition → traditional
- -able: renew → renewable; recycle → recyclable
- -ness: aware → awareness
- -ly: sustainable → sustainably
Key Prefix Patterns
- re- : renew, recycle, reduce
- de- : deforestation (removing forests), depleting (exhausting resources)
- un- / ir- : unsustainable; irreversible
- mis- : mismanagement (poor handling of resources)
Word Family Practice
Study entire word families together rather than isolated words. For example: sustain → sustainable → sustainability → sustainably → sustenance. Similarly: renew → renewal → renewable → renewably. Building these families mentally allows you to handle any gap-fill or word-formation item confidently, regardless of which form is tested.
"The company's commitment (commit) to sustainability (sustain) reflects a strong set of environmental (environment) values."
8. Key-Point Callout and Exam Preparation Summary
The Baccalaureate examination paper is divided into three main sections: Comprehension, Language, and Writing. Each section rewards specific skills that you can systematically build during your preparation.
Section-by-Section Strategy
- Comprehension: Read the entire text once for gist. Then read each question before re-reading relevant paragraphs. Underline key phrases. Distinguish between what the text states directly and what it implies.
- Language: For gap-filling, decide the grammatical category first (noun/verb/adjective/adverb). For linking words, decide the logical relationship first (cause, contrast, addition). For future tenses, underline time markers before writing your answer.
- Writing: Plan your essay in two minutes before writing. Ensure each paragraph has a clear topic sentence. Use a range of vocabulary and grammatical structures deliberately. Proofread for agreement, tense consistency, and punctuation.
Daily Preparation Habits
- Keep a vocabulary notebook organised by word families and collocations.
- Complete at least one gap-fill or word-formation exercise daily, checking morphological rules.
- Read authentic texts on environmental topics to develop domain-specific vocabulary and sharpen comprehension skills.
- Analyse model essays, focusing on how transitions are used, how evidence is integrated, and how the argument is structured.
- Practise full past papers under timed conditions to build exam-day stamina and time management.
💡
Key Point: Sustainable development is not a single policy — it is the integration of economic growth, environmental protection, and social equity. At the Bac, demonstrating this holistic understanding through accurate vocabulary, well-structured arguments, and appropriate grammar will set your work apart. Morocco's leadership in solar energy shows that sustainable development is both a global imperative and a local opportunity. With disciplined preparation and genuine engagement with the theme, you are fully equipped to excel.
