Learning a good range of environment vocabulary is a must as the environment is one of the most common topics to feature in the IELTS exam.
It could be the main topic of your speaking test, you may be asked to write about it, or the environment could come up in either the reading or listening parts of your exam.
You might also need environment vocabulary when answering questions about other subjects such as where you live, transportation or travel.

IELTS Speaking Sample: Environment
1) Do you think pollution is a big problem nowadays?
I think it’s a massive issue. It really worries me how much damage we are doing to the natural environment, especially how we pollute the oceans with plastic waste and release greenhouse gasesinto theatmosphere.
2) What do you do to prevent the environment from pollution?
I recycle as much rubbish as I can and I walk when possible rather than driving or taking public transport in order to reduce my carbon footprint.
3) Are you worried about climate change?
Most definitely. In my country, the weather is changing because of global warming and we get more bad storms than before. Governments and individuals need to do more to combat climate change.
4) Do you use renewable energy?
Not at the moment. I wanted to change my house to solar power but the panels are too expensive for me to buy so, unfortunately, I still use fossil fuels.
5) Do you take an interest in nature?
I love all wildlife. My garden is the perfect habitat for hedgehogs. They are nocturnal but if I go out after dark with a torch I sometimes see one.
Describe an environmental problem you’ve heard about.
You should say:
- what it is
- how long it has existed
- how it affects people’s lives
and explain how you think the problem will develop in the future.
There are a number of serious environmental problems being covered by the media at the moment but the one I’d like to talk about is the deforestation of vast areas of rainforest to grow palm oil. I’m not sure when it started to become a concern to environmentalist but I know that they’re increasingly worried about it.
This land clearance is on a huge scale and the forest is often just burned down. This sends large amounts of greenhouse gas emissions into the atmosphere which contribute to global warming and climate change. This affects everyone on the planet.
Just as important is the effect on the native wildlife. Deforestation to grow palm oil in Borneo and Sumatra destroys the natural habitat of orang utans as well as many other animals. Conservationists estimate that unless the situation changes, the orang utan and Sumatran tiger could become extinct in the wild in the next 5-10 years. In fact, a third of all mammal species in Indonesia are thought to be critically endangered because of this type of unsustainable development.
Furthermore, the oil palm plantations that replace the rich vegetation of the rainforest support very low levels of biodiversity and create a totally a different ecosystem. I don’t fully understand why the loss of biodiversity is such a problem but I did read somewhere that it means that our food crops are more vulnerable to pest and diseases. This could lead to serious food shortages in the future.
I think that the palm oil industry and its associated problems are going to be difficult to change. Perhaps it’s consumers who can have the biggest impact by refusing to buy products containing palm oil which is in around 40-50% of common household products in many developed countries. In the UK, there’s already one major food retailer that has promised to ban palm oil in its own products. This I really encouraging and I hope other companies will do the same soon.
1) What do you consider to be the most serious environmental issues in the world today?
I’d say that global warming and climate change have to come top of the list because these threaten the very future of life on our planet. There are many contributing factors such as the burning of fossil fuels, deforestation for agriculture and due to illegal logging, and large-scale livestock farming.
Another serious concern is for the marine life in our oceans which is under serious threat from pollution, especially waste plastics. These kill or injure thousands of sea creatures every day. Many species of wildlife are also being pushed to the verge of extinction by poaching. It’s shocking to think that beautiful animals such as the tiger are dying out in the wild because of the actions of human beings.
There are many other environmental problems that we need to solve but these are the ones I believe to be the most serious.
2) Do you think it is the responsibility of governments alone to protect the environment?
Not at all. It’s the responsibility of every individual to do their bit to protect the environment. Of course, governments can do a lot to address environmental issues through their policies and the laws they pass. I certainly think that governments should put more pressure on industry to use clean energy and to cut down on the emission of greenhouse gases that pollute the atmosphere and add to global warming.
In my country, the government encourages people to live an environmentally-friendly lifestyle by providing recycling services and facilities and subsidising renewable energy by giving grants to people wanting to run their homes on solar power. If more people took advantage of this, it would certainly help the environment.
3) What measures can individuals take to protect the environment?
There are many ways that each of us can help to care for the natural environment. Firstly, we can recycle as much of our rubbish as possible or, even better, cut down on our use of disposable products.
Secondly, we can become more energy-efficient by insulating our homes, turning off lights when they don’t need to be on and making short journeys by bicycle or on foot rather than going by vehicle. Cutting down on car journeys also means fewer polluting exhaust fumes entering the atmosphere.
Finally, we can make sure that we know about the major conservation issues our world is currently facing. If we are well-informed then we can take action to bring about change.
These are all measure we can take as individuals to help safeguard the environment.

Part 2-style task
Describe an environmental problem that has been in the news. You should say
- when this was
- where the event happened
- what actually took place
and say how you felt about this problem.
Martin: Well … this is an interesting question … there are so many issues I could think of … natural disasters like earthquakes and floods seem to be in the news almost every year … but there was one story recently about some animals that were under threat … it wasn’t focused on one place in particular … it was looking at various animals that could actually become extinct in different African countries … if we don’t take steps to protect them … these were really iconic animals like gorillas … leopards … rhinos … and apparently they’re now listed as endangered species … what made it really depressing was they were in danger thanks to us … in some cases, it was due to a loss of habitat either because people need more agricultural production … or even worse I think because of hunting and poaching … I hate to think of future generations being robbed of the chance to see creatures like these in their natural environment … it’s lucky we have lots of organizations that focus on wildlife conservation … hopefully, with their help, we can put pressure on those in power to do something to stop creatures like these dying out …
