      There are many types of environment pollution in the world, air pollution is one of them. The main cause of air pollution is the smoke and dust released from factories. They are very toxic to us humans. And they are also very bad for the environment. In addition, air pollution is also generated from the exhaust fumes of motor vehicles such as motorcycles and cars. As a result, the air source in the flock is heavily polluted, causing a greenhouse effect, causing the Earth to heat up. The ice from the North and South poles is being melted due to rising sea levels, causing flooding. We need a way to fix them immediately, otherwise the consequences will be even more dangerous.

Water pollution is the dumping of foreign materials in water. Water pollution has the following advantages: helps in disposing harmful materials off the land surface and is inexpensive. Disadvantages of water pollution include: waterborne diseases, death of aquatic life and hindrance to boating activities.Pollution is the introduction of contamination materials into the natural environment that causes adverse changes. There are many forms of pollution, including water pollution, soil pollution and air pollution. All types of pollution are known for their many harmful effects. However, water pollution helps in avoiding other forms of pollution. Dumping of waste in water helps to free the land of harmful materials. When chemicals from factories are dumped in water rather than on land, it means crops from rain-fed agriculture will not be affected. Water pollution prevents health hazards. When materials are dumped in rivers, they become unavailable to human beings and hence cannot affect them, for instance, poisonous food materials.Water pollution increases nutrient loading, leading to eutrophication. Organic wastes such as sewage and farm waste put high oxygen demand on the receiving water body resulting in oxygen depletion with drastic impacts on the entire ecosystem. A variety of pollutants discharged from industries, which include heavy metals, solids, organic toxins, nutrients and oils, reduce oxygen availability. Crops irrigated with water contaminated with heavy metals pose a health risk to humans.
