In a world heading towards climate breakdown, All the World is Green takes us on a journey to discover how much what we put on our table fuels climate change. Through the guidance of scientists, academics, activists, journalists and philosophers, we embark on a journey spanning from China to the USA, leading us to discover how our love for animal products took over our food system, pushing our ecosystems to the verge of collapse for the profit of a handful of corporations. After a journey stretching through Asia, America and Europe, the film leaves the viewer with a choice: remaining part of the problem, or becoming part of the solution.
