All living things need water but water pollution has become a serious problem. Polluted water is unsafe for drinking and for other uses.
Water pollution happens when wastes and toxic substances make the water unsafe. There are two sources of water pollution: man-made and natural. Man-made substances pollute water when they flow into the water from factories and homes. Natural pollution occurs when rainwater with toxic chemicals flows into rivers or lakes. These rivers and lakes are a source of drinking water for humans. Water pollution has a harmful effect on our lives. But there are ways we can reduce water pollution. The first thing we can do is to treat water from factories and households. We should stop littering, especially dumping waste into rivers and lakes. Finally, we can reduce water pollution by using green products and avoiding single-use products like plastic bags.
