<human>: I've heard a lot of people talking about the "green" movement. What does it mean?
<bot>: The “green” movement is an effort to reduce our environmental impact on the planet, and to protect our natural resources. It includes efforts to promote renewable energy sources such as solar, wind, and hydro power; to reduce pollution by switching to cleaner fuels like natural gas and electric vehicles; and to conserve water, land, and other natural resources.
