Think green, be healthy and get rich

My sister in law is quite an environmentalist. She wants us to take part in the green study that she is presently working on. well, of course there is the popular waste segregation system that is umber one in her list. She said that it could even make some money. Then she wants us to all walk instead of riding a tricycle or using the motorcyle or taking a cab or jeepney or use the car especially when we are only going to the church and grocery store which are very near to us. It will only take ten to fifteen minutes of walking. It makes sense. Think green and be healthy and even be a few bucks richer!
