text: In Conclusion, while cars have been and are a great asset limiting the use of them could greatly benefit every one by using lessening stress levels, lowering pollution, and reduce the amount of greenhouse gas. Looks like we're already headed in the right direction.    You just finished a long, hard day at school. You're exhausted, and you can barely keep your eyes open. However, your principle has required you to take an extracurricular activity, and you have to spend another hour at school. After school has ended, I just want to get home and lay in my comfy bed. It would be very irritating if I had to spend another stressful hour at school. I disagree to requiring all students to participate in at least one activity because students need to learn to act on their own interests, they may have a very busy life at home, and it adds unnecessary stress on the kids.
