If I were Mayor, I'd make the world a better place by
outlaw plastic bags, make recycling mandatory, plant trees on each curb, front yard, back yard. Make composting mandatory. make watering your lawns daily illegal. Shut down all the golf courses (water usage).
You're gonna hate me for this but each able being over the age of 3 must and will be forced to exercise 30 minutes a day for 5 days a week!
