As titles go, the name of this animated explainer really hits the mark. Through its clever mix of visual metaphors and diagrams, the film neatly illustrates a stark portrait of a tipping point into environmental crisis. Though filmmaker Leo Murray, who also narrates, is an amiable host, you would be forgiven any feelings of abject despair halfway through this film. But this isn't about denial, anger, depression or any other stages of acceptance - this is about action.

The film was produced as a graduation project from the animation course at the Royal College of Art, which rarely results in such directly politically statements. But it's certainly a successful demonstration of the potential of animation to explain and enlighten in unique ways, and the film's viral success online meant that it was seen by an exponentially bigger audience than the average student short. Murray's continued pursuit of innovative activism saw him help organise the 20ft 'Trump Baby' blimp, which graced many protests against the 45th US President.
