What is Plastic Pollution?
Within Earth & Environmental Science, which covers our planet, its resources and ecosystems, and how people can protect the environment, this topic explains Plastic Pollution. Earth and environment topics show how the planet’s systems shape landscapes, climate and life, with models that make these processes visible.
Check that you can explain Plastic Pollution in your own words and give one example from everyday life. If you can do that, you have understood the core idea.
Understanding Plastic Pollution helps you explain the environment around you and weigh up how people can protect it.
Plastic Pollution in detail
Plastics are cheap, light and durable, so about 400 million tonnes are produced each year, but much is used once and discarded. Because most plastics do not biodegrade, they break into microplastics, tiny fragments that spread through oceans, soil, food and even the air.
Millions of tonnes enter the oceans each year, harming marine animals through entanglement and ingestion, and chemicals can pass up food chains. Solutions include reducing single-use plastics, reuse and refill, better recycling and waste collection, bans on items such as microbeads and plastic bags, biodegradable alternatives and international agreements. Consumer choices and clean-ups help but reducing production is key.
How the interactive helps you understand Plastic Pollution
Watch the bar chart in the interactive. Use any sliders or buttons it offers to change the values and see how the bar chart responds.
Before you change anything, predict the result. Then change one value at a time and check whether your prediction was right. This is a quick way to build a correct mental model of Plastic Pollution.
Real-life uses and examples
- Link Plastic Pollution to a real environmental problem and a possible solution.
- Use a diagram of Plastic Pollution to describe the steps of a process in order.
- Discuss how human activity changes Plastic Pollution, using a named example.
Common mistakes to avoid
- Presenting one cause as the only cause of an environmental change.
- Describing a process without the timescale it works over.
- Learning the definition without testing it. Use the quiz and the interactive to check that you can apply the idea.
