{{BR}}
= Introduction =

'''Plastic pollution''' happens when plastic objects and tiny plastic pieces enter places where they do not belong, such as streets, soil, rivers, lakes, beaches, and oceans. Plastic is useful because it is light, strong, and long-lasting. Those same qualities can become a problem when plastic is thrown away carelessly or escapes from waste systems.

This aiMOOC is designed for '''Grades 5–6'''. You will learn where plastic pollution comes from, how it moves through the environment, why it can harm wildlife and habitats, and what people can do to prevent it. You will also practise observing, asking questions, collecting evidence, explaining causes and effects, and designing solutions.

Look carefully at the image. What kinds of plastic can you identify? Which objects might have been used only once? Which objects could travel if wind or water moved them?

= What Is Plastic Pollution? =

Plastic is a group of materials that can be shaped into many products. You can find plastic in bottles, food packaging, toys, clothes, fishing equipment, electronics, building materials, and many other objects. Because plastic is durable, it may remain in the environment for a long time if it becomes litter.

'''Plastic pollution''' is not only a problem in the ocean. It can appear on land and in freshwater too. A dropped wrapper can be blown into a drain. Rain can wash litter into a stream. Rivers can then carry some of that waste toward lakes or seas. Lost fishing gear can also become marine debris.

[[File:Plastic Pollution in Santa Luzia, Cape Verde.jpg|500px|frameless|center]]

Think like a detective: the plastic in a place may not have been used there. Wind, rain, rivers, waves, and ocean currents can move waste far from its starting point.

{{BR}}
== From Useful Product to Pollution ==

A simple pathway can look like this:

# [[English:Plastic production|Production]]: Raw materials are turned into plastic products.
# [[English:Consumption|Use]]: People use the products, sometimes for only a short time.
# [[English:Waste management|Collection]]: Used products should be collected, reused, recycled where suitable, or safely disposed of.
# [[English:Litter|Leakage]]: Poorly managed waste or litter can escape into the environment.
# [[English:Marine debris|Movement]]: Wind and water can carry plastic through streets, drains, rivers, and coastlines.
# [[English:Fragmentation|Breakdown]]: Sunlight, waves, and rubbing can break larger plastic into smaller pieces.

The best point to stop pollution is often '''before''' plastic becomes litter.

{{BR}}
= Microplastics: Tiny Pieces, Big Questions =

'''Microplastics''' are plastic pieces or fibres smaller than 5 millimetres. Some begin small, while others form when larger plastic items break into fragments. Fibres can also come from synthetic textiles. Scientists find microplastics in many environments and study how they move and how they affect living things.

[[File:Microplastic.jpg|500px|frameless|center]]

A microplastic can be smaller than a pencil eraser. Because these pieces are tiny, they are difficult to collect once they spread through water or soil. This is one reason why prevention matters.

{{BR}}
== How Scientists Study Microplastics ==

Scientists may collect samples of water, sand, or sediment and examine the particles carefully. They record information such as size, shape, colour, and location. Good science also means preventing accidental contamination of samples and comparing results using clear methods.

You can practise the same scientific habits in class without handling real microplastics. For example, you can model how particles spread by using safe paper dots in a tray, or analyse photographs and public data.

{{BR}}
= How Plastic Pollution Affects Living Things =

Animals can be harmed when they become tangled in plastic items such as lost nets, lines, or loops. Some animals may also swallow plastic because they mistake it for food. Plastic waste can cover habitats, and litter can change the places where organisms feed, rest, or reproduce.

[[File:Sea turtle entangled in a ghost net.jpg|500px|frameless|center]]

This photograph shows why lost fishing gear is sometimes called a '''ghost net''': even when people are no longer using it, the net can continue to trap animals.

Plastic pollution is also connected to people. Communities may need to spend time and money cleaning beaches, rivers, parks, and streets. Litter can make places less pleasant and may affect fishing, tourism, and recreation.

{{BR}}
= The 3 Rs and the Waste Hierarchy =

A useful way to think about waste is the '''waste hierarchy'''. It gives priority to preventing waste first.

[[File:Waste hierarchy.svg|500px|frameless|center]]

'''Reduce''' means using fewer unnecessary materials. '''Reuse''' means using an item again instead of replacing it quickly. '''Recycle''' means processing suitable waste so that material can be used again. Recycling is helpful, but it does not work for every plastic item or in every local system. That is why reducing unnecessary single-use items and reusing durable products can be especially important.

{{BR}}
== Smart Choices at School and Home ==

You can make useful changes without trying to be perfect. Start by observing where plastic is used and wasted. Then choose actions that are realistic in your local area.

# [[English:Waste prevention|Prevent waste]]: Refuse an unnecessary item when you do not need it.
# [[English:Reuse|Reuse]]: Carry a reusable bottle, lunch container, or bag when appropriate.
# [[English:Waste sorting|Sort correctly]]: Follow your local rules for recycling and rubbish.
# [[English:Repair|Repair]]: Keep durable items in use when they can be safely repaired.
# [[English:Community cleanup|Clean up safely]]: Join supervised cleanups and use gloves or tools as instructed.
# [[English:Environmental education|Share knowledge]]: Explain the problem and solutions using evidence.

Never pick up sharp, medical, chemical, or unknown waste. Tell an adult instead.

{{BR}}
= People Taking Action =

Solutions can involve individuals, schools, businesses, scientists, communities, and governments. A student can reduce waste in a lunchbox. A school can improve refill stations and sorting bins. Designers can create reusable or easier-to-recycle products. Communities can improve waste collection. Researchers can study where pollution comes from so that prevention can target the source.

[[File:Beach plastic waste 3.jpg|500px|frameless|center]]

A cleanup can remove litter that is already present, but prevention is also important. If the same kinds of items appear again and again, people can ask where they come from and how to stop them from becoming waste.

{{BR}}
= Thinking in Systems =

Plastic pollution is a '''systems problem'''. An object has a life before and after you use it. Think about the material, the product design, transport, how long the item is used, what happens when it is discarded, and whether local waste systems can manage it.

A strong solution asks more than, "Can this be recycled?" It also asks, "Do we need this item?", "Can it be reused?", "Can it be designed with less material?", and "How can we keep it out of nature?"

This connects plastic pollution to [[English:Sustainability|sustainability]], [[English:Circular economy|circular economy]], [[English:Ecosystem|ecosystems]], [[English:Ocean conservation|ocean conservation]], [[English:Environmental science|environmental science]], and [[English:Citizenship|citizenship]].
