debris
Definition
Debris is any small piece of waste or broken material. It can be natural, such as leaves or twigs, or it can be man-made, such as plastic or metal. Debris can be found in all environments, from the ground to the ocean.
Debris can be a problem for the environment. It can pollute waterways, harm wildlife, and even cause fires. There are a number of ways to reduce debris, including recycling, composting, and properly disposing of waste.
Here are some examples of debris:
- Natural debris: Leaves, twigs, branches, rocks, sand, shells
- Man-made debris: Plastic, metal, glass, paper, food scraps
Debris can be a problem for the environment in a number of ways. It can:
Pollute waterways: Debris can block waterways, making it difficult for fish and other animals to swim. It can also release harmful chemicals into the water.
- Harm wildlife: Debris can entangle animals, injure them, or even kill them.
- Cause fires: Debris can catch fire, which can spread to forests and other areas.
- There are a number of things that can be done to reduce debris, including:
- Recycling: Recycling helps to keep debris out of landfills and incinerators.
Composting: Composting turns food scraps into fertiliser, which can be used to reduce the need for chemical fertilisers.
Properly disposing of waste: It is important to dispose of waste properly so that it does not end up in the environment.

AQA Science Exam Question and Answer
Task:
Explain the environmental impact of debris in marine ecosystems and provide two examples of how debris can harm marine life and habitats.
Answer:
- Debris in marine ecosystems can have severe environmental impacts on marine life and habitats.
- Harm to Marine Life: Marine animals often mistake plastic debris for food, leading to ingestion and potential blockage of their digestive systems. For example, sea turtles might consume plastic bags, mistaking them for jellyfish, causing digestive issues and even death.
- Disruption of Habitats: Debris, such as discarded fishing nets, can become entangled in coral reefs, damaging these fragile ecosystems. The entanglement not only harms corals but also traps and drowns marine species like fish and crustaceans.
- Moreover, debris can leach harmful chemicals into the water, affecting the entire food chain. To mitigate these impacts, proper waste management, recycling, and raising awareness about the consequences of marine debris are essential steps toward protecting our oceans and marine life.
