The term pollution means the discharge of a toxic or contaminating substance that is likely to have an adverse effect on the natural environment or life. Pollution is a very serious problem, making life more difficult for not just humans, but even plants and animals. There are many types of pollution such as air pollution, water pollution, and soil contamination. First let’s begin by talking about air pollution and how it affects us. Air is 99.9% nitrogen, oxygen, water vapor and insert gases. Air pollution occurs when gases, dust particles, or smoke are introduced into the atmosphere that causes harm to all living organisms. Air pollution can be caused by both human and natural actions. Natural occurrences are forest fire, volcanic eruptions, and radiation. Human activities that result in air pollution include: emissions from manufacturing industries, burning fossil fuels from any transportation vehicles. Air pollution can affect our health in many ways with both short-term and long-term effects. Some people are much more sensitive to pollutants than others. Young children and elders often suffer more from the effects of air pollution. Examples of short-term effects include irritation to the eyes, nose and throat. Short-term air pollution can aggravate the medical conditions of people with asthma. Long-term effects can include chronic respiratory disease, lung cancer, heart disease, and even damage to the brain. On the other hand, let’s move on to water pollution. This pollution occurs when particles, chemicals, or substances that make water contaminated are discharged directly or indirectly into water bodies without enough treatment to get rid of harmful compounds. Water is a necessity and essential of life. People, animals, and crops rely on clean water. Contaminated water will not only kill animals, but will eventually lead to more death of human from the poisoned seafood.

The last pollution I will be talking about is ground pollution. This pollution occurs...
