If the entire world population lived like the average citizen of Luxembourg, eight planets of earth would be needed to provide sufficient resources for everyone. Eng Äerd presents long-term initiatives of Luxembourg citizens fighting against the depletion of natural resources. Different initiatives already in existence are presented by those who drive and supervise them. The film wants to encourage viewers to change their thinking, both in their private lives and at the level of associations, as well as from an economic and political point of view. It explores the motivations of these Luxembourgish environmentalists and shows that everyone can contribute to building a new healthier and more solidary society in harmony with nature and for the good of all.
