text: In comparison, car accidents? They are the absolute worst. It not only affects 1 car but it could affect 2 or 3. Maybe even more. Limiting car usage could prevnt so many accidents and that means no more hospital visits. Source 2, paragraph 4 says "Congestiion was down 60% in the capital of Frnce after 5 days of intensifying smog." That means that there was 60 percent less traffic jams and accidets in 5 days! That's an amazing improvment. I always wished that people couldn't get hurt or that I could save someones life, so that what I will try to do. Drive less, or drive only when it's needed. Don't leve your car running. A big negative is don't speed and watch all around you. You can prevent killing someone, not just that, but you can decrease the amount of accidents that can happen. Don't make an asamine choice and drive because you feel like it. Help save this earth. It's really all we have left.
