READ UNTIL END!!
I think it has had a positive effect on the world because, in today’s society some of us are fortunate enough to have a motorized vehicle to get us place to place although it did pollute the air, we now have came up with different ways to solve that problem and still are like electrical cars are a thing now. Overall I feel like life would be very difficult without having something to get you around in. I would switch up the words a little and maybe try to come up with a few words of your own, make it flow nicer and come up with better ideas
