The aim of the project is to make teenagers aware of the consequences of global warming on our planet and to make them think about what they could do now or in the future to protect our planet and to fight against this major issue. The COP21 gives us the opportunity in the media to know more about this worldwide problem and make children feel more concerned. We want our pupils to learn more about the topic and make them produce slogans and advice in English in relation to this issue. But as it is a worldwide issue, we thought it would be interesting to work with pupils from all around the world to imagine slogans and advice all together and translate them in as many languages as possible. Schools belonging to réseau UNESCO are more than welcome to participate.
