First let them watch a short video and ask them to describe what it is about. T can ask them the following questions:
1) What can you see in the video?
2) What causes the environmental problem?
3) How to solve it?
Then ask them to read the brochure about a new, environmentally friendly hotel which is opening. Let them pay attention to the words in blue, especially those formed with “eco”
For example:
Eco-tourists, ecosystem, eco-friendly,
(Let them guess the meanings of all these words with “eco”. Then tell them prefix ‘eco’ comes from Greek and means ‘earth’. It is used in many words to talk about the environment, such as ‘ecology’ and ‘eco-tourism’. Ask them to write six words that include the prefix ‘eco’ by using their dictionary if necessary.

Possible answers:
Eco-friendly, eco-travel, eco-trip, eco-tourists, ecologist, ecosystem
