Water pollution is one of the most serious problems in our modern world. It means the mixing of harmful things with water, which makes it unsafe for people, animals, and plants. In Bangladesh, this issue is rising fast because of population growth and careless use of natural resources.
The main causes of water pollution are factory waste, farm chemicals, oil spills, and household garbage. Industrial areas release untreated chemicals into rivers. Farmers also use pesticides and fertilizers, which mix with rainwater and reach ponds and canals.
Polluted water is very dangerous for human health. It spreads diseases like diarrhea, cholera, hepatitis, and typhoid. Thousands of people suffer from these illnesses every year due to drinking or using unclean water.

Factories play a big role in pollution. They release dyes, oils, and toxic liquids directly into rivers without treatment. This destroys aquatic life and makes water unusable for drinking, farming, or fishing.
People can reduce water pollution by throwing waste in the right place, reusing plastic, and using safe farming methods. Factories should treat their waste before releasing it.

Water Pollution Paragraph for HSC (300 Words)
Water pollution is one of the greatest environmental threats of our time. It happens when harmful substances like chemicals, plastics, and waste mix with water and make it unsafe. In a country like Bangladesh, where rivers are the lifeline, pollution has become a daily concern.
There are many causes of water pollution. Factories release untreated chemicals and dyes directly into rivers. Farmers use fertilizers and pesticides, which get washed away into canals and ponds. Household garbage, sewage, and plastic also add to the problem.
The effects of water pollution are very serious. People who drink or use dirty water suffer from diseases like cholera, diarrhea, typhoid, and skin problems. Unsafe water also affects children the most, as they are weaker and get sick easily.
Animals and plants also face danger. Fish die in polluted water as oxygen levels drop. Aquatic plants cannot grow, and the natural food chain gets damaged. Even birds and animals that depend on water are badly affected.
Rivers and seas lose their beauty and strength due to pollution. Many rivers in Bangladesh have become shallow, black, and lifeless. Polluted seas also harm fishermen, as they lose their source of income.
Factories play a major role in this crisis. They dump toxic liquids, oils, and dyes without proper treatment. This destroys aquatic life and makes the water unfit for drinking or farming.
To reduce pollution, people must change their habits. Waste should not be thrown into rivers or canals. Factories should set up treatment plants to clean their waste. Farmers should use natural methods instead of harmful chemicals.
Clean water is the source of life. Without it, no human, plant, or animal can survive. Saving water is not only a duty but also a responsibility for our future.
