The purpose of this project is to raise students´ awareness and spread knowledge of climate change in their schools and local communities. Through this awareness, they will exchange experiences and opinions, which are the proper attitudes towards a major environmental problem, the waste production, in particular excessive consumption of plastic. These will help them understand the changes caused by human activity and teach them the responsibility they have as citizens. By applying the 3R rule – reducing, recycling and reusing – and using creativity, we want our students to be able to take sustainable measures. The activities proposed in this project aim to encourage students to take action to make the World a Happy Planet.
