Water pollution happens when harmful substances or contaminants get into the water. These can be things like chemicals, trash, or even excessive nutrients from fertilizers. When this pollution enters rivers, lakes, or oceans, it can harm the aquatic ecosystem.

Polluted water can have many negative effects. It can kill fish and other aquatic organisms directly. It can also harm plants that rely on the water for nutrients. This disruption in the food chain can have far-reaching consequences for the entire ecosystem. In addition, pollution can reduce the amount of oxygen in the water, making it difficult for fish and other aquatic life to breathe.

Water pollution can come from many sources, including factories that release pollutants into nearby water bodies, improper disposal of chemicals and waste, runoff from agriculture, and even everyday activities like littering. It is important for us to be aware of these sources and take steps to prevent water pollution to protect the health of aquatic ecosystems.
