Let’s look at one more passage.

“Building Green” is one way to conserve natural resources and protect the environment, but it is expensive and requires dedication to change. There are other ways you can conserve energy that will result in reduced pollution, and you don’t have to move! Paying attention to the heating and cooling in your home will help conserve energy. If you turn the thermostat down in the winter and up in the summer, the result is a significant decrease in the use of electricity or gas. Even changing the temperature a few degrees will save a bundle of energy. Putting away the car keys will help conserve natural resources. Cars use gasoline, which comes from a nonrenewable resource. If you can, take a bus or train, ride a bike, or walk. Doing so will help you save money on gasoline, reduce the amount of fossil fuels you use, and help the environment by preventing the burning of those fuels. Going green is easier than you think! In the first sentence of the second paragraph, the author makes the point that paying attention to heating and cooling our homes will help conserve energy. What reasons and evidence does the author use to support this point?
