I used to ride a taxi cab wherever I go. Its convinient and comfortable. However, it contributes to pollutants in the air. My resolve is, walk or use public transport whenever possible ( if weather is ok). It was hard at first, its hot and humid. So I adjusted the time that I would need to leave and move around. (between 5-7 in the evening). It was cooler and still early, people are still on the streets. you get to see your environment as it really is. Walking around gives me more ideas for projects to make things here better.
