Introduction: Environmental pollution is considered one of the most serious problems facing the modern world. It threatens human life and other living organisms and negatively affects the main components of the environment—air, water, and soil. With rapid industrial and technological progress, the levels of pollutants in the air and water have increased, making humans more vulnerable to chronic diseases and health problems. Types of Environmental Pollution: 1. Air Pollution: It results from the emission of toxic gases from factories and vehicles, such as carbon dioxide, carbon monoxide, and sulfur and nitrogen oxides. This type of pollution leads to respiratory diseases such as asthma, chronic bronchitis, and lung cancer. 2. Water Pollution: It occurs due to the discharge of industrial and agricultural waste into rivers and seas, contaminating drinking water sources. This pollution causes serious diseases such as cholera, typhoid, and viral hepatitis. 3. Soil Pollution: It results from the excessive use of pesticides and chemical fertilizers, or from the leakage of toxic substances from waste materials. This leads to contamination of agricultural crops and the entry of harmful substances into the human body through food. 4. Noise Pollution: It refers to the increase in loud sounds from vehicles, factories, and loudspeakers, which affects hearing and causes nervous tension and sleep disorders. The Impact of Pollution on Human Health: Continuous exposure to pollutants leads to the emergence of several diseases, including: • Respiratory and heart diseases. • Weakness of the immune system. • Nervous system disorders. • Increased risk of cancer. Children and the elderly are among the most affected groups due to their weaker immune systems compared to other age groups. Ways to Reduce Pollution: • Using environmentally friendly means of transportation such as bicycles and electric cars. • Increasing green spaces and planting trees in cities. • Proper waste disposal and recycling. • Raising environmental awareness and encouraging sustainable behaviors. Conclusion: Protecting the environment is a collective responsibility. Every individual must contribute to reducing pollution to preserve human health and the planet. A clean environment means a healthy life and a safe future for generations to come. Hassan Naji Hussein Al-mustaqbal University .The First University in Iraq
