Scavenging is the act of searching for and collecting discarded materials or items that are no longer in use. This practice can be undertaken by humans, animals, or even in ecological contexts. Human scavenging often involves individuals searching through refuse or abandoned sites for items that can be repurposed, repaired, sold, or consumed. This can range from salvaging scrap metal and recyclable materials to finding usable food or clothing. Historically, scavenging was a common survival strategy, and it continues to be a means of livelihood or necessity for many people in various parts of the world.

In the animal kingdom, scavenging refers to the consumption of carrion, which is the flesh of dead animals. Scavengers play a crucial role in ecosystems by cleaning up carcasses, preventing the spread of disease, and recycling nutrients. Common animal scavengers include vultures, hyenas, coyotes, and certain insects like flies and beetles. Their adaptations, such as keen eyesight or a strong sense of smell, aid them in locating food sources.

Ecologically, the term scavenging can also be applied to the breakdown and recycling of dead organic matter within an environment. Decomposers like bacteria and fungi are essential biological scavengers that break down complex organic compounds, returning vital nutrients to the soil and water, which then become available for plant growth. This continuous process is fundamental to the functioning of all natural ecosystems.
