L'essentiel du cours

Le développement durable (Sustainable Development) est un mode de développement qui répond aux besoins du présent sans compromettre la capacité des générations futures à répondre aux leurs. Pour les élèves en Sciences Agronomiques, ce concept repose sur trois piliers :

  1. Économique : Rentabilité et gestion efficace des ressources.
  2. Social : Équité, santé, éducation et lutte contre la pauvreté.
  3. Environnemental : Préservation des écosystèmes, gestion de l'eau et lutte contre le changement climatique. Vocabulaire clé : Renewable energy, biodiversity, carbon footprint, eco-friendly, natural resources, conservation, global warming.

Méthodes à maîtriser

  • Rédaction d'un paragraphe argumentatif : Utiliser des connecteurs logiques (Furthermore, consequently, in addition, therefore).
  • Analyse de texte : Identifier les causes (ex: pollution) et les solutions (ex: reforestation).
  • Utilisation des modaux : Exprimer l'obligation (must, have to) et la suggestion (should, ought to) pour proposer des solutions écologiques.

Exemples corrigés

Exemple de phrase pour l'examen : "We must reduce our carbon footprint to protect the environment." Analyse : "We" (sujet), "must" (modal d'obligation), "reduce" (verbe), "our carbon footprint" (complément), "to protect" (but).

Erreurs fréquentes

  • Confondre environment (milieu) et environmental (adjectif).
  • Oublier le "s" à la troisième personne du singulier dans les textes argumentatifs.
  • Utiliser "sustainable" comme synonyme de "long" au lieu de "durable".
