50+ Essential Environment Vocabulary for IELTS Writing & Speaking

Today we’re going to learn about the topic “The environment.”

Why is this so important? Well, in both Writing and Speaking, you’ll often be asked about issues like climate change, pollution, or renewable energy. And if you only say things like “pollution is bad” or “protecting the environment is important”, you won’t get a high score for vocabulary. Why? Because the examiner wants to see that you can use a wide range of vocabulary.

So in this lesson, I want to give you 50+ useful words, collocations, idioms, and phrasal verbs, along with sample IELTS answers, so that you can sound more natural, confident

Useful Phrasal Verbs Related to Environment

IELTS Speaking Part 1: Topic Environment

Do you care about environmental issues?

Yes, I do. I think protecting the environment is very important because problems like climate change and air pollution directly affect people’s health and also put future generations at risk.

What environmental problems are common in your country?

I’d say the most serious problems are air pollution, climate change, and plastic waste. For example, many big cities suffer from heavy smog due to traffic, while plastic bottles and bags are often thrown into rivers and seas, which damages marine life.

Do you do anything to protect the environment?

Yes, I try to recycle, cut down on plastic, and save electricity at home. These might seem like small actions, but I believe they add up. If everyone makes small lifestyle changes, together they can make a big difference in the long run.

Would you like to work in an environmental job?

I don’t think so. I already try to protect the environment in my daily life by making small changes, but I’ve never really thought about working in that field. To be honest, I’ve always dreamed of becoming a doctor since I was a child, so that’s the career path I want to follow.

IELTS Speaking Part 2 – Topic: Environment

Describe an environmental problem in your area.
You should say:

• what it is
• why it happens
• how it affects people
• and explain what can be done about it.

Useful vocabulary

• wreak havoc on = cause a lot of damage or problems.
• prolonged droughts = long periods with little or no rain.
• fetch = go to get and bring something back.
• floods = large amounts of water covering normally dry land.
• malnutrition = poor health caused by not having enough food or nutrients.
• stuck in a cycle of poverty = trapped in a situation where people remain poor and cannot escape poverty.
• renewable energy = energy from natural sources like wind, sunlight, or water that can be used again.
• fossil fuels = fuels such as coal, oil, and natural gas that pollute when burned.
• stricter punishments = stronger or more severe penalties for breaking rules or laws.
• add up = gradually increase to make a significant total or effect.

IELTS Speaking Part 3 Environment

Do you think individuals can make a real difference in protecting the environment?

Yes, I do. One person alone might not make a huge impact, but when millions of people change their habits, the effect is powerful. For example, if individuals reduce, reuse, and recycle, avoid single-use plastics, and use energy more efficiently, they can help combat issues like climate change and the energy crisis.

People can also switch to public transport, walk, or cycle instead of driving to cut down on emissions. Another simple action is to support eco-friendly companies by buying sustainable products. These small choices may seem insignificant, but together they really add up and make a noticeable difference.

What role should governments play in environmental protection?

Governments play a crucial role because they have the power, resources, and authority to make large-scale changes. They can introduce stricter punishments for companies that break environmental laws, and they can fund renewable energy projects such as wind farms and solar panels.

Another responsibility is to launch public awareness campaigns to educate people about eco-friendly lifestyles. Governments can also invest in better public transport systems so that people rely less on private cars, and they can promote reforestation programs to restore ecosystems. In my opinion, individuals alone cannot solve these problems, so governments need to take the lead and set an example.

What do you think the future of the environment will look like?

It’s really hard to predict because the future depends on the actions we take today. If countries continue to prioritize economic growth over sustainability, the environment will keep suffering and we might face more extreme problems such as rising sea levels, food shortages, and even mass extinction. In the worst-case scenario, life on Earth could be severely threatened.

However, I’m still optimistic. If governments act responsibly, and individuals also contribute by adopting greener lifestyles, I believe future generations will live in a cleaner, healthier, and more sustainable world. It all depends on how seriously we treat the problem now.
