Effects of air pollution in points
Pollution issues escalated as population growth far exceeded viability of neighborhoods to handle their waste problem. Water pollution , by the discharge of wastewater from commercial and industrial waste intentionally or through spills into surface waters ; discharges of untreated domestic sewage , and chemical contaminants, such as chlorine , from treated sewage; release of waste and contaminants into surface runoff flowing to surface waters including urban runoff and agricultural runoff, which may contain chemical fertilizers and pesticides ; also including human feces from open defecation — still a major problem in many developing countries ; groundwater pollution from waste disposal and leaching into the ground, including from pit latrines and septic tanks ; eutrophication and littering. Effects of Water Pollution Pollutants in water resulting from trash, oil spills, sewage spills and run-off from agricultural fields, construction sites and factories affect native plant and animal species. All of which also contribute to water pollution. The fumes from car exhausts contain dangerous gases and particulates including hydrocarbons, nitrogen oxides, and carbon monoxide. Air pollution can have a serious heath impact on humans. Mainstreaming air pollution reduction into policies to combat noncommunicable diseases leads to multiple benefits for the environment, economy and health. It also affects astronomical observations and activities by making the stars almost invisible. Indoor areas can become polluted by emissions from smoking and cooking. Children, senior citizens and people who work or exercise outside are at a greater risk. Agricultural air pollution comes from contemporary practices which include clear felling and burning of natural vegetation as well as spraying of pesticides and herbicides  About million metric tons of hazardous wastes are generated each year. Coastal developments, therefore, are encouraged to turn off their lights or cover them at night Impacts A littered coastline in the Philippines Human activities contaminate ecosystems around the world—from pole to pole, from the highest mountains to the ocean deep.
Air pollution comes from both natural and human-made anthropogenic sources. While some chemicals may be harmless, others can cause damage.
Air pollution effects
Reformers began to demand sewer systems and clean water. Humans have ways to cut greenhouse gas emissions and avoid the consequences of global warming, a major climate report concluded. Thus, preventing plants in the process of photosynthesis. An October study by the Lancet Commission on Pollution and Health found that global pollution, specifically toxic air, water, soils and workplaces, kill nine million people annually, which is triple the number of deaths caused by AIDS, tuberculosis and malaria combined, and 15 times higher than deaths caused by wars and other forms of human violence. In the hierarchy of controls, pollution prevention and waste minimization are more desirable than pollution control. Visitors, especially women, often became desperate when nature called. Human Health The decrease in quality of air leads to several respiratory problems including asthma or lung cancer. There are currently few training programmes on air pollution and its health effects, and little related information, in public health education. This event was caused by a period of cold weather combined with windless conditions that formed a dense layer of airborne pollutants, mostly from coal plants, over the city.
Excessive burning of fuel which is a necessity of our daily lives for cooking, driving and other industrial activities; releases a huge amount of chemical substances in the air every day; these pollute the air. Animals higher in the food chain accumulate these toxins in higher and higher concentrations, a process called biomagnification.
Some of this material accumulates in the centers of ocean gyres, creating great garbage patches. Use of insecticides and pesticides absorbs the nitrogen compounds from the soil making it unfit for plants to derive nutrition from.
The Industrial Revolution brought an infusion of untreated chemicals and wastes into local streams that served as the water supply.
The burning of fossil fuels for transportation and electricity produces both primary and secondary pollutants and is one of the biggest sources of air pollution.
