Sustainable Development — English Bac Lettres

Dans le programme du Bac Lettres

English is a major subject in the Bac Lettres stream, with a coefficient of 4 — second only to Arabic Language (coefficient 7) and ahead of History-Geography and Philosophy (coefficient 3). There is no Mathematics in the stream. The high coefficient raises the bar: richer vocabulary, more developed argumentative writing, and firmer control of register and style are expected, and the English mark genuinely shapes the average.

À l'épreuve

Three parts: Reading Comprehension, Language, and Writing. In the Lettres stream the Writing task is longer and more demanding — a structured essay with a clear thesis, developed arguments on both sides, illustrative examples and a personal conclusion — and language accuracy and range are scored throughout.

Objectifs d'apprentissage

Reuse this vocabulary field in the Bac Lettres Reading answers and in the argumentative essay (coefficient 4)
Use energy and climate vocabulary: renewable / fossil energy, carbon footprint, greenhouse gas emissions, global warming
Name environmental issues: pollution, deforestation, water scarcity, loss of biodiversity, waste
Define sustainability: meeting present needs without compromising future generations
Argue how economic development and environmental protection can be reconciled

Notions clés

Energy and carbon footprint

renewable energy (solar, wind, hydro) vs fossil fuels (coal, oil, gas); carbon footprint (the total greenhouse gas emissions caused by a person, product or activity); to reduce / offset emissions.

Environmental issues

air and water pollution, deforestation, water scarcity, loss of biodiversity, plastic waste, soil degradation — the problems sustainable development aims to address.

Sustainability: economy and environment together

sustainable development = development that meets present needs without compromising the ability of future generations to meet theirs. It seeks a balance between economic growth, social fairness and environmental protection.

Erreurs fréquentes

Confusing renewable (naturally replenished: sun, wind) and non-polluting: nuclear power is low-carbon but not renewable; biomass is renewable but can pollute.

Using pollution as a countable noun: say “air pollution” / “levels of pollution”, not “pollutions”.

Treating sustainable development as “stopping all development”: it is about developing differently, not stopping.

Exemple corrigé

Énoncé

Write a sentence explaining how a country can pursue economic growth while lowering its carbon footprint.

Correction

Name the tension. Growth usually means more energy use; a lower carbon footprint means fewer emissions.

Give the reconciling idea. Shifting energy sources from fossil fuels to renewables allows both at once.

Result. “A country can keep growing economically while cutting its carbon footprint by investing massively in renewable energy, so that new industries and homes are powered by solar and wind rather than by coal and oil.”

3 exercices pour t'entraîner

Exercice 1

Easy

Classify as renewable or fossil: solar, coal, wind, oil.

Voir la correction

Renewable: solar, wind. Fossil: coal, oil.

Exercice 2

Medium

Complete: “Cycling to school instead of being driven reduces your ___.” (carbon footprint / biodiversity / deforestation)

Voir la correction

carbon footprint — cycling produces no emissions, so it lowers the greenhouse gases you are responsible for.

Exercice 3

Hard

Explain in one sentence why the definition of sustainable development refers to “future generations”.

Voir la correction

Because sustainability is about fairness over time: using resources and polluting today at a rate that leaves future generations unable to meet their own needs would not be development, but a transfer of the cost onto people who cannot object.

Questions fréquentes

How does this theme connect to the science subjects?

Energy sources, greenhouse gases and pollution are studied in physics-chemistry and life-and-earth science; this chapter gives candidates the English vocabulary to bring that knowledge into an essay with concrete, credible examples.

Is Morocco a good example for this theme?

Yes — the Noor solar complex near Ouarzazate, wind farms, and water-scarcity policy are specific, current Moroccan examples that make an essay stronger than generic ones.

What are the three pillars of sustainable development?

Economic (growth and jobs), social (fairness, health, education) and environmental (protecting resources and ecosystems) — a good answer keeps all three in view rather than only the environment.

English is coefficient 4 in the Lettres stream — how do I revise it seriously?

Treat it as a core subject. For each of the 31 chapters, fix the rule or the word field with two solid examples, and write at least one full essay a fortnight under timed conditions. Read short English articles to build argumentative vocabulary and sentence variety, since range and accuracy are marked directly.

How do I use this theme in the Bac Lettres essay without sounding generic?

Anchor each key term in one concrete, personal example — a place, a person, a situation you know. A specific illustration in accurate English scores better than a long list of terms with no support, on any of the society prompts in the programme.
