Discuss an environmental solution

Discussing an environmental solution is not just about knowing the words for pollution, recycling or energy. It is about knowing the right phrases at the right moment. In a real discussion, you need to propose an idea, support it, evaluate someone else's idea, and finally reach a decision. Each of these "moves" has typical English phrases, and using them makes you sound natural, fluent and polite.

Below is a toolkit of phrases for each function. Notice the register: "How about using reusable bags?" is friendly and works in a casual discussion between friends. "One solution would be to install water fountains" sounds more formal and is better in a written proposal. In a real conversation you can mix the two levels.

A small but important point: in English (UK), it is very common to use softeners such as I think, perhaps or might when you propose an idea. Saying "We should ban plastic bags" sounds strong and direct — useful, but it can also start an argument. "I think we could perhaps ban plastic bags" sounds more polite and is more likely to invite a calm discussion. Save the strong "We should" for the moment when you are summing up and pushing an idea forward. The practice below lets you hear these phrases in a real conversation and use them yourself.

Two friends discuss the plastic waste on their street. Listen for the functional phrases from the table.

Read the suggestion aloud. Use friendly, rising intonation at the end.

Read the supporting phrase aloud. Stress main, benefit and cuts down.

You are about to listen to a conversation between two flatmates, Maya and Ben. They have just read a news article about plastic pollution in the River Lea, a river in east London, and they are standing in their kitchen drinking tea and trying to come up with a realistic solution they could actually try in their neighbourhood.

As you listen, remember that you do not need to understand every word. Good listeners use three different passes:

1. Gist listening: ignore the detail and ask yourself, What is this conversation about in general?
2. Specific information: listen for one particular fact, such as a number, a name or a place.
3. Detail listening: focus on a smaller piece of information, often to fill a gap.

You will do all three passes in the practice after the dialogue.

Prediction: Before you listen, look at the three ideas below. Which one do you think Maya and Ben will choose? Why?

• Stop buying single-use plastic bottles at home
• Organise a community clean-up of the river next month
• Start a petition against plastic bags in local shops

Pre-taught words:

• single-use: used once and then thrown away (e.g. plastic cups, water bottles)
• petition: a written request signed by many people, asking someone in power to make a change
• community: the people who live in the same area

Maya and Ben discuss solutions to plastic pollution in the River Lea. Listen for gist first, then for the specific ideas they mention, and finally for their decision.

Gist: What is this conversation mainly about?

Specific information: How many different ideas does Maya mention from the article?

The sounds /p/ and /b/ look almost the same on paper, and they are made in almost the same place in the mouth, but English treats them as two completely different phonemes. Both are bilabial plosives: to make them, you close your lips firmly together, build up a small pocket of air behind them, and then open your lips so the air escapes in a short pop. The big difference between the two sounds is what your vocal cords are doing while your lips are closed.

To make /p/, your vocal cords do not vibrate. The sound is voiceless, and when you open your lips, the air comes out as a strong puff, especially at the start of a stressed syllable. To make /b/, your vocal cords do vibrate, so the sound is voiced. Hold your hand about five centimetres in front of your mouth and say pa — you should feel a clear burst of air on your skin. Now say ba with your hand in the same place. You will feel much less air, and you will probably also feel a small buzz in your throat. That buzz is voicing, and it is what makes /b/ a different sound from /p/.

This contrast matters because many Arabic speakers replace English /p/ with /b/, so words like propose, plastic and planet can sound like "bropose", "blastic" and "blanet". The fix is simple once you can feel the difference: focus on the airflow, not just the lips.

In the practice, you will listen to a minimal pair, then repeat short words and phrases that contain /p/ and /b/.

How to make /p/ and /b/: close your lips, build pressure, then release. For /p/, do not use your voice — just a strong puff of air. For /b/, switch your voice on — feel a low buzz in your throat. Try the hand test: air in front of the mouth = /p/; buzz in the throat = /b/.

Say the word problem. Focus on the strong /p/ at the start, not a buzz.

Say the phrase ban plastic bottles. Listen for the /b/ in ban and bottles, and the strong /p/ in plastic.

Say the full sentence. Keep the /p/ in plant crisp and unvoiced.

Reading is one of the most important skills for following environmental news, understanding reports and reading proposals. B2 readers should be able to read a short article quickly for the main idea, and then go back and find specific facts such as numbers, names and dates. The second skill — finding specific facts — is called scanning, and it is the focus of this section.

Strategy box: Scanning for specific information When you scan a text, you do not read every word. You move your eyes quickly down the page, looking only for the piece of information you need — a date, a number, a name or a key word. Before you scan, decide exactly what you are looking for. Then let your eyes jump until you find it. Scanning is perfect for finding facts in reports, articles and web pages. It is different from skimming (reading quickly for the general idea) and from close reading (reading carefully for full understanding).

Pre-taught key words:

• ban (noun / verb): an official rule that stops something, or the act of stopping it
• initiative (noun): a new plan or project
• residents (noun): people who live in a particular place
• survey (noun): a set of questions used to find out what people think

In the next step, you will read a short news article about a small English town that tried a "zero-waste" idea on one of its streets. Read it once for the general idea, then read it again and scan for the specific numbers and facts.

Greenford's Zero-Waste Street

The small town of Greenford, in the south of England, has just finished a one-year trial called the Zero-Waste Street. The local council banned single-use plastic cups and plastic cutlery on one high street, gave every resident a free reusable cup, and added ten new recycling bins.

The results are impressive. Street litter fell by 60% in just twelve months, and 85% of residents said in a recent survey that they wanted the scheme to continue. The council has now announced that three more streets will join the initiative next year.

Tip: read the article once for the general idea, then scan it again to find the numbers in bold.

Gist: What is the article mainly about?

Detail: According to the article, how many more streets will join the initiative next year?

In this section you will use the functional phrases from earlier in a real, short discussion about an environmental problem in your own town or neighbourhood. You will first hear a model conversation, then read the key sentence aloud, and finally hold your own short discussion with the AI.

Useful phrases for the discussion

Tips for natural speaking:

• Use contractions in speaking: "I think we should", not the long form — the first sounds more natural.
• Use word stress to make your key point clear. In "I think we should start a recycling centre", the stress usually falls on start and recycling, because they carry the new information.
• Use softeners when you disagree. "I'm not sure about that" is much more polite than "That's wrong."
• Remember the /p/ vs /b/ difference from the pronunciation section, especially in words like propose, problem, public and bottle.

In the roleplay step at the end, the AI will play a neighbour. Your job is to propose a solution, react to their idea, and agree on a next step.

A short model discussion between two neighbours. Listen for the phrases in the table.

Read the key model sentence aloud. Stress start and recycling.

Read the polite disagreement aloud. Keep the tone friendly, not critical.

A proposal is a short, structured piece of writing that suggests a solution to a problem. You might write a proposal at work, at school, or in a community group. A good proposal is short, clear and easy to read, because busy people do not have time to read long texts.

A good proposal usually has four short parts:

1. The problem — what is wrong? (one or two sentences)
2. The solution — what do you want to do?
3. The benefits — why is it a good idea?
4. The action needed — what should happen next, and who should do it?

Model proposal

Problem: Our school uses over 2,000 plastic bottles every week, and most of them end up in landfill. Solution: We should install four new water fountains and let students bring reusable bottles into class. Benefits: This would cut our plastic waste by about 80% and save the school around £1,500 a year. Action needed: We need the headteacher's approval and about £500 to buy and install the fountains.

Strategy tip: Using headings to structure a proposal Writers of proposals use short, clear headings to separate the four parts. This makes the proposal easy to read and shows the reader exactly where each idea is. In your own writing, label the four parts clearly with words such as Problem, Solution, Benefits and Action needed. Keep the headings short and parallel, and put each one on its own line.

Common errors to avoid:

• Writing a long introduction before the proposal. Keep it short and go straight to the four parts.
• Mixing past, present and future tenses. Use the present simple for the problem and the benefits, and would + infinitive for the predicted benefits.
• Forgetting the action needed. A proposal without a clear next step is just an idea, not a plan.

In the practice, you will check the strategy in the model, then write your own short proposal on a topic of your choice and read it aloud.

Strategy reminder: structure your proposal with four short headings. Use Problem, Solution, Benefits and Action needed. Use the present simple for facts and the problem, and would + infinitive for predicted benefits (e.g. This would cut waste by 80%).

Look at the model proposal. Which heading should the sentence "We should install four new water fountains and let students bring reusable bottles" go under?

Write a short proposal on a topic of your choice — for example, a school recycling scheme, a community clean-up, or a local ban on plastic bags. Use the four headings from the model. When you finish, read your proposal aloud.
