A big commodity for some people here is scraps. Plastic, wire, paper, anything that can be collected seems to have a use to someone. One more plastic bottle is one more piece of food in your mouth. So many people roaming the streets with large sacks looking for whatever was just thrown away in a trash can, moments later another person with a bamboo basket will walk by and check the same trash can, a few moments later another and another 24 hours a day.
