Scavenging means to pick up and gather something usable from discarded waste materials. It’s the act of gathering things that other people have discarded and no longer want for their use. The act of scavenging is quite common in most developing countries where there are harsh economic conditions which practically make it difficult for people to live a comfortable life.
Such conditions push some very poor people into going to rubbish dumps to scavenge for food, reusable, and resalable items. This they do in order to survive the unfavorable living condition.
Scavenging is risky. For instance, exposure to sharp objects like broken glass, metals, old needles can inflict wounds which might result in serious diseases is one of the risks scavengers face all the time. Also, scavengers sometimes get run over by dump trucks.
All in all, scavenging is real.
