Pollution is a process in which air, water, land or any other parts of the environment become unsafe for humans. Unfortunately, humans are the ones who contribute to this pollution.
Let’s take a look at the different types of pollution:
The biggest contributors to land pollution are industrial waste and household garbage. Hazardous waste comprises of all kinds of liquids, sludge waste, solids, and stuff that contains substances that are harmful to the environment and to human health. Industries contribute to hazardous waste from industries such as refining, mining, petroleum, chemical manufacturing and pesticide manufacturing. Households contribute to hazardous wastes comprising of motor oil, paints and their solvents, aerosol cans, fluorescent lights and ammunition.
Air pollution is mostly caused due to dangerous gases such as carbon monoxide, sulfur dioxide, chemical vapors, and nitrogen oxides. Greenhouse gases and secondhand smoke also make up for a significant amount of air pollution. Air pollution is responsible for killing about 2 million people every year.
Water pollution takes place when any kind of chemicals and/or dangerous foreign substances are drained into the water. The most common contaminants of the United States include mercury, bacteria, nitrogen and phosphorus.
Artificial warming of water, also known as thermal pollution is also a very harmful practice. When a power plant or factory makes use of water to cool its operations and then discharges the hot water in the water body, thermal pollution takes place.
Although one can’t see it, noise pollution is caused by the sound coming from various industries, planes and also underwater noise pollution is caused by ships in water bodies. Noise pollution not only affects the ear drums but also leads to stress, high blood pressure and various other health issues.
This might be unheard of but light pollution is caused by the use of artificial light. Here are some of the side effects of light pollution:
- Singing of birds at odd hours due to the presence of artificial light.
- The development of flowers is also disrupted by artificial light.
- Light pollution is also a great contributor to smog
- Light pollution also makes it difficult for astronomers to see the stars properly.
Some Facts About Pollution:
According the the World Health Organization, air pollution alone is responsible for 6.7% of deaths all over the world.
The World Health Organization has also stated that about 7 million people die a premature death each year just because of the alarming levels of air pollution. That makes it 1 out of every 8 people who die all over the world!
The pollution caused by China can alter the weather patterns in the U.S.A. It takes only 5 days to carry the heavy air pollution from China to the United States via the jet stream and then it poses as an obstacle to the clouds and prevents them from producing snow and rain.
