Do you believe that the world has changed for the better, or for the worse?

I think both, my reasons are, first, we have more technology and better transportation that will help us, like the technology to take and give to others, and the cars and trains ect. to help us to get from one place to another a bit quicker. Also i think worse because of the green house causes, the  cars,oil,and other things we use in our everyday life is slowly ruining the planet, ecosystem ect. there are downsides and upsides to both.
