Pollution

Pollution is the presence in or introduction into the environment of a substance or thing that has harmful or poisonous effects. Pollution is a big problem around the world, and we release a variety of toxic chemicals into the atmosphere when we burn the fossil fuels we use every day. Pollution hurts our environment greatly.

Pollution has a negative effect on natural elements that are an absolute need for life to exist on earth, such as water and air. Indeed, without it, or if they were present in different quantities, animals, (including humans) and plants could not survive. We can identify a couple of types of pollution on Earth: air pollution, water pollution, and soil pollution.

Cars and factories also make pollution, including nitrogen oxide, sulfur dioxide, and hydrocarbons. These chemicals react with sunlight to produce smog, a thick fog or haze of air pollution. The smog is so thick in places like China, people can barely see the sun.

According to the Department of Environmental Protection (DEP), “Millions of Americans live in areas where urban smog, particle pollution, and toxic pollutants pose serious health concerns. People exposed to high enough levels of certain air pollutants may experience:  Irritation of the eyes, nose, and throat; wheezing, coughing, chest tightness, and breathing difficulties, worsening of existing lung and heart problems, such as asthma, increase risk of heart attack.”

Pollution is a big problem around the world and letting tons of deadly chemicals into the atmosphere when we burn the fossil fuels we use every day. We need to stay conscious of the environment and make an effort to stop polluting.
