Vocabulary of the environment

Global-challenge texts rely on precise terms. l’ambiente (the environment), il riscaldamento globale (global warming), il cambiamento climatico (climate change), l’inquinamento (pollution), i rifiuti (waste), lo sviluppo sostenibile (sustainable development), le energie rinnovabili (renewable energy), il riciclo / la raccolta differenziata (recycling / sorted waste collection), proteggere (to protect), sprecare (to waste). In Italy, la raccolta differenziata is a widespread daily civic practice, and environmental protection is increasingly treated as a shared responsibility across the Italian and European public sphere.

The congiuntivo of necessity and obligation

Calls to action lean heavily on the congiuntivo after expressions of necessity: bisogna che (it is necessary that), è necessario che, è urgente che, occorre che (it is required that), è ora che (it is time that). Bisogna che agiamo subito (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: affinché / perché (so that), a patto che / purché (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 passato prossimo), followed by proposed solutions framed with necessity (bisogna che…) or the conditional (si potrebbe…, we could…). Signal words like tuttavia (however), quindi / perciò (therefore), and per questo (this is why) mark the logical turns. Tracking this problem-then-solution shape helps you identify a text’s main argument.

Worked example

Interpret: « Il pianeta si riscalda rapidamente. È urgente che riduciamo i rifiuti e che ognuno faccia uno sforzo per proteggere l’ambiente. » — Analyze the mood and the argument.

1.Gloss: "The planet is warming rapidly. It is urgent that we reduce waste and that everyone make an effort to protect the environment."
2.The first sentence states the problem in the present (si riscalda).
3.È urgente che triggers the congiuntivo: riduciamo (ridurre) and faccia (fare) are subjunctive forms.
4.Note the call to shared responsibility: ognuno faccia uno sforzo — "everyone" must contribute.
5.Interpret: the text follows a problem-to-action structure and frames environmental protection as an urgent collective duty, a common Italian/European civic perspective.

Answer: The problem is stated in the present (si riscalda), then the necessity trigger è urgente che forces the congiuntivo (riduciamo, faccia). The argument urges collective, urgent action, reflecting the perspective that protecting the environment is a shared civic responsibility.

Checkpoint

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

Watch out

Do not confuse bisogna + infinitive with bisogna che + congiuntivo. Bisogna agire (one must act — general, no subject) uses the infinitive, but bisogna che agiamo (we must act — specific subject) requires the subjunctive after che.

An Italian text moves from describing rising pollution to « È ora che ognuno agisca ». The phrase signals that the author is:

On the exam

On persuasive texts, locate the necessity triggers (bisogna che, è urgente che, è ora che) to find the author’s proposed action. These subjunctive clauses usually contain the thesis — what the writer wants the reader to do.
