Portfolio: Use the picture and the text to give a two-minute talk about water pollution. In the talk:
- explain why water pollution is a problem
- give some examples of ways that water is polluted
- explain how your audience can reduce water pollution
Water pollution poses a serious threat to our environment and health. When harmful substances enter our waterways, they create a chain reaction of damage. Fish and aquatic plants struggle to survive as pollutants reduce oxygen levels in the water. Dangerous chemicals can work their way up the food chain, eventually reaching our dinner tables. Even the water we drink can become contaminated, putting human health at risk.
The sources of water pollution are all around us. After heavy rains, fertilizers from farms and lawns wash into rivers, feeding unnatural weed growth that suffocates marine life. Carelessly discarded plastic waste kills sea creatures who mistake it for food or become entangled in it. Toxic substances like motor oil, antifreeze, and industrial chemicals often find their way into storm drains that empty directly into waterways. Even ordinary household activities contribute to the problem when soaps, detergents, and other chemicals go down our drains.
Each of us has the power to make a difference through simple daily actions. Proper waste disposal is crucial — recycling whenever possible and never littering helps keep trash out of our water systems. Choosing environmentally friendly cleaning products and natural alternatives to chemical pesticides reduces harmful runoff. Water conservation efforts, like fixing leaky faucets and using water-efficient appliances, decrease the amount of contaminated water needing treatment. Perhaps most importantly, sharing knowledge about water protection helps multiply these positive effects throughout our community.
