Urbanization is the rise in the number of people in urban areas. It may be due to an increase in population or decline in agriculture or both of these reasons. The increasing number of people in the urban areas causes a lot of problems like pollution, traffic jam, etc.
Pollution due to urbanization
The increasing number of people in the urban areas leads to many problems among which pollution is one. Increasing urbanization leads to an increase in the use of factories, industries, and transport systems, which are all major contributors to pollution. This occurs because of increased demand for goods and services.
Urbanization has affected our water resources as well. As there is a constant need for more water, this increases the number of waste products discharged into water bodies like rivers and lakes.
It has also affected air quality as there is a constant need for more power which is generated from combustible substances that release harmful gases into the atmosphere. The waste products from factories are also released into the atmosphere which affects their quality as well.
Couse of Urban Pollution
The main cause of urban pollution is the burning of fossil fuels by motor vehicles and industry. Most pollution in towns is caused by motor traffic. Thousands of cars, lorries, and buses in our streets produce fumes that are dangerous to our health.
The exhaust fumes from cars and other vehicles contain carbon monoxide, lead, nitrogen oxides, and harmful hydrocarbons. When these gases mix with sunlight they produce smog and acid rain which damages buildings, plants, and animals.
Inefficient combustion of fossil fuels also produces a lot of soot and smoke which can cause respiratory diseases like asthma, bronchitis, and lung cancer.
Impact of Urbanization on the Environment
Urbanization and the environment are interrelated. The impact of urbanization on the environment is one of the most serious problems in the world today. It has been recognized that the problem is caused by both natural and human factors.
It has been observed that urbanization affects many aspects of the natural environment, such as climate change, agricultural land, forests and wildlife, soil erosion, and loss of biodiversity.
A major problem with urbanization is that it can lead to the loss of farmland. Urban areas in developed countries use up a large proportion of their land for buildings, roads, and other infrastructure, which may result in an increase in food prices if there is not enough farmland left to grow crops on.
Types of Environmental Pollution
There are many types of environmental pollution. Some are visible, such as trash in the ocean and smog in the air. Others are invisible, including radiation and toxic chemicals.
Air pollution is a general term for a variety of substances that contaminate the atmosphere. They can be aerosols (solid or liquid particles suspended in air) or gases. Major sources of air pollution include car exhaust fumes, smoke from factories, and soot. Air pollution can cause health problems such as cancer, respiratory illness, and heart disease. Smoke from wildfires also contributes to air pollution.
Water pollution occurs when water contains too much of certain substances or organisms for it to be safe for human use. According to the EPA, about one-third of U.S. waterways are contaminated with pollutants like pesticides and fertilizers, sewage, oil, and toxic chemicals from the industry. Water pollution can cause disease and even death in humans who drink contaminated water or eat contaminated fish.
Noise pollution is an often-overlooked type of environmental contamination that affects people’s health. A number of common sounds — horns honking, jackhammers drilling, machines humming — can exceed safe levels if they occur regularly or at close range.
Steps to Reduce Pollution
There are several ways that we can reduce pollution. One of the best ways is to simply consume less, which will reduce the number of resources needed to produce goods. Instead of buying those throw-away bottled waters, use a reusable bottle that you fill with tap water. Use cloth shopping bags instead of plastic ones, or bring your own bag when you go shopping. These two things alone can make a huge difference in how much plastic is dumped into landfills every year.
Another good way to reduce pollution is by simply recycling more. In the United States, recycling has been growing steadily for the last five years, with more and more people recycling aluminum cans, paper, and plastic bottles. However, there is still a lot more work that needs to be done in this area.
One of the biggest contributors to pollution in the United States is our transportation system. Cars and trucks account for about one-third of all carbon emissions in the country, and most of these emissions come from burning gasoline and diesel fuel. One way we can help reduce this problem is by driving less and using public transportation more often when possible.
