text: In concluson, Being able to save your money, and help out the Earth can always be a good thing. Polluting the air can lead to many problems in the future and that could damage many lives and places. Always know how to respect your planet by always using less gas or no gas at all. Biking and walking can lead to a better future and it would turn out better than using a car.                    I am against using the value of technology to read students' emotional expressions. I'm not saying that this type of technology is bad though it isn't good either. I feel like this type of technology has no purpose what so ever.
