Why the environment is a key B2 First topic

The environment is one of the most common discussion topics in the exam. You might be asked in Speaking Part 3 how a town could encourage people to protect nature, write an essay about reducing plastic waste, or read an article about a scientist studying glaciers. Because everyone has something to say about it, the difference between a B1 and a B2 answer is often the vocabulary: environmentally friendly instead of good for nature, fossil fuels instead of oil and gas and things.

Learn the groups below in order. Then connect them to travel vocabulary (flying, tourism and its effects) and money and shopping vocabulary (consumer habits and packaging), because exam questions often combine these topics.

False friends and confusing pairs in environment vocabulary

Trap: The contamination in my city is terrible. (Spanish contaminación, Italian contaminazione)

Fix: Say the environment. Ambient is a rare adjective (ambient music, ambient temperature).
Trap: We should protect the nature.
Fix: Nature normally has no article: We should protect nature.
Trap: The weather is changing because of pollution.
Fix: Weather is day to day (rain today). Climate is the long-term pattern. The climate is changing.
Trap: An ecological car / ecological products. (Italian ecologico, Spanish ecológico, Polish ekologiczny, German ökologisch)
Fix: English prefers environmentally friendly, eco-friendly or green. Ecological is mostly used in science (an ecological study).
Trap: We must avoid that people throw rubbish. (Spanish evitar que, Italian evitare che)

Use it in the exam: Speaking Part 4

Environment questions in Speaking Part 4 usually ask who is responsible, or whether small actions matter. Show B2 range by using cause-and-effect collocations (have an impact on, lead to, result in) and give a concrete example. Find more questions in our Part 4 question bank.

Sample Part 4 answer: environment

Examiner: Do you think individuals can really make a difference to environmental problems, or is it up to governments?

I'd say both, but governments have much more power. If one person cuts down on plastic or cycles to work, it only reduces their own carbon footprint a little. But if a government bans single-use plastic or makes public transport cheaper, millions of people change their habits at the same time. That said, individuals still matter, because governments usually take action when lots of voters show they care. In my town, for example, a group of students started cleaning up the river every month, and now the council has given them funding.

Why it works

Takes a clear position but shows both sides ('That said…').
Uses collocations from this page: cut down on, carbon footprint, bans, single-use, take action, cleaning up.
Explains cause and effect clearly ('if…, millions of people change their habits').
Ends with a specific local example rather than a vague statement.

Environment questions for speaking practice

Answer each question aloud for 30 to 45 seconds. Try to include one cause-and-effect phrase in each answer.

Should schools teach more about environmental problems?
Is recycling enough, or do we need to change our lifestyles more?
Who should pay to clean up pollution: companies or taxpayers?
