The movie gave all the viewers a chance to see the environmental issues that happened not just in our own country but around the world. Every time when a government found a new land that hasn’t been used, they would immediately turn it into an industrial base for financial benefit. The significant reason that helped them to ruin the natural ecological environment is the decent salary these companies provide to the employees. People would always choose wealth over the natural environment because nature still seemed consumable to them. How to convey the awareness and sense of urgency to protect the environment is the key to change the situation. As what Max said， If the government could pay more to the companies who grow trees than the ones who cut down the trees，people will definitely choose to the one that provides more wedge and get a sense that growing tree was the more valuable thing to do.
