Question

explain 3 three causes of Air Pollutioneffect of air pollution

Answer 1

Health Effects of the Pollution We Cause

Exposure to emissions of lead, mercury, sulfur dioxide, particulate matter, carbon dioxide, and ozone-forming nitrogen dioxides are hazardous to public health. Toxic compounds, like mercury and lead, poison organ systems and can lead to brain damage and death. In parts of the country where lakes and waterways have been contaminated with mercury from electric power plants, fish are no longer safe to eat because they, too, are contaminated with heavy metal pollutants. Other pollutants, like ozone and particulate matter, cause respiratory and other health problems, particularly in children and the elderly.

 

Environmental Effects

Climate change on a global scale has been attributed to increased emissions of carbon dioxide (CO2), a greenhouse gas. A global average temperature rise of only 1C could have serious implications. Possible consequences include melting of polar ice caps; an increase in sea level; and increases in precipitation and severe weather events like hurricanes, tornadoes, heat waves, floods, and droughts. Indirect effects include increases in infectious disease, weather-related deaths, and food and water shortages. All these effects put a stress on ecosystems and agriculture, and threaten our planet as a whole.

Other atmospheric effects of air pollution include urban smog and reduced visibility, associated with ozone-forming nitrogen oxides and volatile organic compound emissions. Sulfur dioxide and nitrogen oxides combine with water in the atmosphere to cause acid rain, which is detrimental to forests and other vegetation, soil, lakes, and aquatic life. Acid rain also causes monuments and buildings to deteriorate.

Economic Effects

The effects of air pollution on human health and the environment have economic impacts. According to the Healthy People 2000 report [5], each year in the United States:

The health costs of human exposure to outdoor air pollutants range from $40 to $50 billion.An estimated 50,000 to 120,000 premature deaths are associated with exposure to air pollutants.People with asthma experience more than 100 million days of restricted activity, costs for asthma exceed $4 billion, and about 4,000 people die of asthma.

The Environmental Defense Fund (EDF) article, "Why is it Better to Buy Green Electricity?"[1], states that acid rain causes $6 billion a year in damage to crops, forests, lakes, and buildings. The potential economic impact of global warming is estimated to be in the billions of dollars. While green sources of electricity may cost more, they do not incur the external costs of traditional fossil fuel-based generation. The EDF article states that:

"Increasing reliance on green sources reduces financial risks such as future regulations, taxes on greenhouse gases, and price fluctuations associated with fossil fuels. Gre
