50 ESL Discussion Questions About the Environment and Sustainability

Environment and sustainability topics work brilliantly for speaking practice because they hit three sweet spots at once: students care about them, they appear in every major English exam, and they generate genuine disagreement - which is what turns a discussion into a real conversation.

Teachers know the problem with discussion questions: half the class drifts off whenever only one student is speaking. YapYapGo is a classroom speaking practice tool for ESL teachers that runs every pair on the same question simultaneously, so the whole room is engaged at once.

Here are 50 questions organised by CEFR level, each designed to produce extended, opinion-based pair discussion rather than factual recall.

YapYapGo includes environment as one of its discussion topic categories, with questions automatically matched to age group and CEFR level. But these work just as well spoken aloud or projected for the class.

Tool tip: YapYapGo's Topic Discussion mode lets teachers select specific themes and CEFR levels, then pairs students automatically. Questions are drawn from a bank that tracks what each class has already discussed, so conversations stay fresh across multiple lessons.

Classroom formats

Quick discussion (10 min): 3 questions, 3 minutes each, new partners every question. Simple and effective. Debate format: Turn any B2+ question into a motion: "This house believes nuclear energy is the best solution to climate change." Assign sides, 90 seconds each, then open discussion. YapYapGo's Debate mode handles the timer and motion display. Jigsaw format: Give each pair a different question from the same level. After discussing, pairs join into groups of four and share what they talked about. Doubles the speaking time.
