removing natural gas from the ground. He examined the subject again in Gasland Ⅱ. Fox was against traditional fossil fuels (矿物燃料) and in support of renewable energy. In his third film, Fox says pollution from fossil fuels must be reduced. Without limits，there will be more extreme weather, like dry weather, rising sea levels and lack of food and water. "When you really meet that head on，it causes unbelievable danger."

　　 Fox notes there are things that climate cannot change."Those are our value structure and that is what the film starts to explain. We start to really emphasize the things that are inside－courage, love, generosity and creativity. I think those are the centers of what we talk about when we talk about a response to climate change."

　　 In the new film, Fox travels through a sunless forest in the Amazon with local activists to measure oil spills. He goes to a village in Ecuador to learn how people there stopped a pipeline from being built. He joins young people in Australia to stop ships from entering the port of Newcastle.

　　 "You should probably know the negative part of what we're about to do. This is the short list: drowning, arrest, being run over by boats, being carried away in water into the Pacific Ocean, cultural disrespect and big waves."

　　 Also in the film，Fox talks to Ella Zhou, an energy expert, She explained the importance of what she calls "moral imagination(道德想象力)"．"I think that it forces us to get out of our box of thinking about, for example, what is being successful. It allows us to have a moral value about what we want as a person. What do we want to do for the world and for ourselves？"
