    šŸŒŽ World Change

    When rubbish is not disposed of properly, wind and rain can carry it into drains. Drains lead to rivers. Rivers flow into the sea. A single plastic bottle dropped on the ground can travel kilometres away. Some plastic breaks into tiny pieces called microplastics. This happens when plastic is left in the sun, hit by waves, blown by wind, or rubbed against sand and rocks for a long time. The heat from the sun makes the plastic weaker and more brittle. Moving water and rough surfaces slowly crack and tear it apart. Instead of disappearing, the plastic just breaks into smaller and smaller pieces. These pieces can become so tiny that fish and other sea animals cannot see them and may mistake them for food.

    🐠 Cause and Effect

    Fish eat microplastics. Birds eat fish. Larger animals eat those birds. Plastic moves up the food chain. Scientists have even found microplastics in human blood and lungs. That means the plastic problem eventually comes back to us.

    šŸ™ļø People and Life

    Beaches covered in plastic can stop visitors from coming. When beaches are dirty, fewer people want to visit or play there. After all, would you want to swim in an ocean filled with rubbish? Fishermen may also catch less fish, and sea animals can get trapped in nets and plastic packaging. Cleaning the ocean is very expensive and very difficult. It is much easier to stop plastic before it reaches the sea. 🌱
