Air pollution can occur naturally or be caused by human activities. [4] Air pollution causes around 7 or 8 million deaths each year. [5] [6] It is a significant risk factor for a number of pollution-related diseases, including heart disease, stroke, chronic obstructive pulmonary disease (COPD), asthma and lung cancer.
The use of GMO crop plants engineered for herbicide resistance can also indirectly increase the amount of agricultural pollution associated with herbicide use. For example, the increased use of herbicide in herbicide-resistant corn fields in the mid-western United States is decreasing the amount of milkweeds available for monarch butterfly larvae.
Bad management practices include poorly managed animal feeding operations, overgrazing, plowing, fertilizer, and improper, excessive, or badly timed use of pesticides. Pollutants from agriculture greatly affect water quality and can be found in lakes, rivers, wetlands , estuaries, and groundwater .
Illustration of air pollutants generated by U.S. power plants (includes both coal-fired and oil-fired plants) During combustion, the reaction between coal and the air produces oxides of carbon, including carbon dioxide (CO 2 , an important greenhouse gas ), oxides of sulfur (mainly sulfur dioxide , SO 2 ), and various oxides of nitrogen (NO x ).
Turning existing city infrastructure green by installing plants can filter out fine dust and noise, reduce urban heat island effects, and even reduce stress. All it takes is regreening 20 percent ...
Most places in the world have pollution above the acceptable standard. Here’s how each region fares. Air Quality Is Bad Pretty Much Everywhere, New World Pollution Report Finds
Pesticides contribute to air pollution. Pesticide drift occurs when pesticides suspended in the air as particles are carried by wind to other areas, potentially contaminating them. [50] Pesticides that are applied to crops can volatilize and may be blown by winds into nearby areas, potentially posing a threat to wildlife. [51]
The other product, nitrate (NO 3 −), is a key nutrient for plant growth. This excess nitrate from ammonia nitrification favors nitrophilous plants (those that prefer high nitrate concentrations) and disadvantages others. For example, an increase in nitrophilous plant populations shade other plants from necessary sunlight.
