A ban on vehicles would definitely be a challenging factor for us human. It will affect everything we do. Although it would eradicate pollution from our environment and give us a very conducive environment to dwell in. Running to animals for help would also generate pollution within our environment and that would be bad for us as well, don't you think the prices of these animals would increase and possible, everyone won't be in possession of these animals. I hope this doesn't happen at all.

I wish you a good luck!
