We now know that man-made climate change is real and that it poses a great threat to the planet and its inhabitants. Current data suggest that we need to reduce greenhouse-gas emissions in developed countries by at least 80% by 2050 in order to have a chance of staying below an average temperature rise of over 2°C . Factory farming is a major contributor to the climate change challenge, releasing vast volumes of greenhouse gases. It is our desire, that by implementing this project, we will influence students' awareness of thinking about the possible consequences of climate change and how they can contribute to mitigating those consequences. The eTwinning project is directed at secondary school students aged 13 - 19 based on cooperative work between the schools, they will prepare presentations, questionnaires, drawings, essays, games, quizzes etc. and finally work will be the common book. The project should be lasts from 16th October until the end of May.
