Vocabulary of the environment

Global-challenge texts rely on precise terms. l’environnement, le réchauffement climatique (global warming), le changement climatique (climate change), la pollution, les déchets (waste), le développement durable (sustainable development), les énergies renouvelables (renewable energy), le recyclage (recycling), protéger (to protect), gaspiller (to waste). France hosted the Accord de Paris (2015 Paris Agreement), and environmental protection is treated as a shared civic duty, a value that recurs across Francophone media.

The subjonctif of necessity and obligation

Calls to action lean heavily on the subjonctif after expressions of necessity: il faut que (it is necessary that), il est nécessaire que, il est urgent que, il est temps que (it is time that). Il faut que nous agissions maintenant (We must act now). Because these clauses urge what should happen rather than state a fact, the verb takes the subjunctive. You will also meet purpose conjunctions that trigger it: pour que and afin que (so that), à condition que (provided that).

Reading arguments and solutions

Interpretive texts about the environment usually move from problem to call for action. Watch for the structure: a description of a threat (often present or passé composé), followed by proposed solutions framed with necessity (il faut que…) or the conditional (on pourrait…, we could…). Signal words like cependant (however), par conséquent (consequently), and c’est pourquoi (that is why) mark the logical turns. Tracking this problem-then-solution shape helps you identify a text’s main argument.

Worked example

Interpret: « La planète se réchauffe rapidement. Il est urgent que nous réduisions nos déchets et que chacun fasse un effort pour protéger l’environnement. » — Analyze the mood and the argument.

1.Gloss: "The planet is warming rapidly. It is urgent that we reduce our waste and that everyone make an effort to protect the environment."
2.The first sentence states the problem in the present (se réchauffe).
3.Il est urgent que triggers the subjonctif: réduisions (réduire) and fasse (faire) are subjunctive forms.
4.Note the call to shared responsibility: chacun fasse un effort — "everyone" must contribute.
5.Interpret: the text follows a problem-to-action structure and frames environmental protection as an urgent collective duty, a common Francophone civic perspective.

Answer: The problem is stated in the present (se réchauffe), then the necessity trigger il est urgent que forces the subjonctif (réduisions, fasse). The argument urges collective, urgent action, reflecting the Francophone perspective that protecting the environment is a shared civic responsibility.

Checkpoint

Which sentence correctly uses the subjonctif after an expression of necessity?

Watch out

Do not confuse il faut + infinitive with il faut que + subjonctif. Il faut agir (one must act — general, no subject) uses the infinitive, but il faut que nous agissions (we must act — specific subject) requires the subjunctive after que.

Checkpoint

A French text moves from describing rising pollution to « Il est temps que chacun agisse ». The phrase signals that the author is:

On the exam

On persuasive texts, locate the necessity triggers (il faut que, il est urgent que, il est temps que) to find the author’s proposed action. These subjunctive clauses usually contain the thesis — what the writer wants the reader to do.
