US
- /pəˈlut/
Description
- make dirty
- contaminate
- harm the environment
Imagine a sparkling clear river full of life. Now picture someone carelessly dumping trash into it. To pollute means to make something dirty, unsafe, or harmful, especially by adding waste or poisonous substances. It is not just about rivers and lakes; people can pollute the air we breathe and the soil where our food grows.
Pollution is not always intentional. Sometimes it happens as a result of human activity, like smoke from factories or exhaust from cars. But whether it is accidental or deliberate, it damages nature and harms living things. Think about oil spills in the ocean, plastic hurting wildlife, or smog hanging over cities. It is a serious problem that affects us all.
To pollute means to contaminate the natural environment with harmful substances, or to make a place dirty, unsafe, or unhealthy. It is most often used for damage to air, water, or land, but it can also be used in a broader or metaphorical way for spoiling something that should stay clean or pure.
Historically, "pollute" comes from the Latin word polluere, meaning "to defile" or "to stain." That idea of making something unclean is still at the heart of the word. We often talk about polluting water sources such as rivers, lakes, and oceans with chemicals, sewage, or plastic waste. Air can be polluted by vehicle exhaust, smoke, and industrial emissions. Soil can be polluted by pesticides, heavy metals, and poor waste disposal.
However, "pollute" is not limited to physical substances. People sometimes use it figuratively. For example, someone might say that lies pollute a public debate or that hateful speech pollutes an online space. In these cases, the word suggests that something valuable has been spoiled or made worse.
The consequences of pollution are far-reaching. It can harm human health, damage wildlife, and upset the balance of whole ecosystems. From dirty drinking water to breathing problems and climate change, the effects can spread widely. Understanding what it means to pollute, and how to prevent it, is an important step toward a healthier future.
