This trend had a greater impact on daily life than many believed and changed the way many people viewed their personal impact on the world.

More and more people are looking into growth sectors such as solar energy, hydropower and wind energy. The Green Movement is important because it has impacted everyone's lives. New laws have been created and most people now live life considering the impact it has on the environment, which is a big change in mindset compared to a hundred years ago..
