Clean Air
The first thing all beings need is clean air, then clean water and good food to survive. Without clean air nothing will survive. Unfortunately Air, soil, water and foods are polluted with our own hands.
Once up on a time our air, soil and water used to be clean one, but...
Man has polluted Air, Water, Soil, foods by his own hands
Soil pollution Water pollution
Air pollution is the introduction of chemical, particulate matter, or biological materials that cause harm or discomfort to human or other living organisms, or damage the natural environment, into the atmosphere.The atmosphere is a complex dynamic natural gaseous system that is essential to support life on planet Earth. Stratospheric ozone deletion due to air pollution has long been recognized as a threat to human health as well as to the Earth's ecosystems. An air pollution is known as a substance in the air that can cause harm to humans and the environment. Pollutions can be in the form of solid particles, liquid droplets, or gases. In addition, they may be natural or man-made.Pollutions can be classified as either primary or secondary. Usually:
primary pollutions are substances directly emitted from a process, such as ash from volcanic eruption, the carbon monoxide gas from a motor vehicle exhaust or sulfur dioxide released from factories.
Secondary pollutions are not emitted directly, rather they form in the air when primary pollutions react or interact. An important example of a secondary pollutant is ground level ozone one of the many secondary pollutants that make up photochemical smog. Note that some pollutants may be both primary and secondary: that is they are both emitted directly and formed from other primary pollutants. About four percent of deaths in the United States can be attributed to air pollution, according to the environmental Science Engineering Program at the Harward School of public health.
SOIL POLLUTION is caused by the presence of man-made chemicals or both alteration in the natural soil environment. This type of contamination typically arises from the rupture of underground storage tanks, application of pesticides. Percolation of contaminated surface water to subsurface strata, oil and fuel dumping, leaching of wastes from landfills or direct discharge of industrial wastes to the soil. The most common chemicals involved are petroleum hydrocarbons, solvents, pesticides, lead and other heavy metals. This occurrence of this phenomenon is correlated with the degree of industrialization and intensities of chemical usage. The concern over soil contamination stems primarily from health risks, both of direct contact and from secondary contamination of water supplies, mapping of contaminated soil sites and the resulting cleanup are time consuming and expensive tasks, requiring extensive amounts of geology, hydrology, chemistry and computer modeling skills. It is in North America and Western Europe that the extent of contaminated land is most well known, with many of countries in these areas having a legal framework to identify and deal with this environmental problem; this however may be just the tip of the iceberg with developing countries likely to be the next generation of new soil contamination. China and United States have the most widespread soil contamination, have actually been leaders in defining and implementing standards for cleanup. Other industrialized countries have a large number of contaminated sites.
She is a girl. She eighteen years old. This has been as a result of the greedy, eager and unconcerned people who have destroyed their country and have stolen their wealth and made a civil war, and selling arms to the ignorant people to kill each other in the name of God or whatever....
STARVATION is s severe reduction in vitamin, nutrient, and energy intake, and is the most extreme form of malnutrition. In humans, prolonged starvation (in excess of 1-2 months) causes permanent organ damage and eventually death. According to the World health Organization, hunger is the gravest single threat to the world's public health the WHO also states that malnutrition is by far the biggest contributor to child mortality.
WATER POLLUTION is the contamination of water bodies such as lakes, rivers, oceans, and groundwater. All water pollution affects organisms and plants that live in these water bodies and in almost all cases the effect is damaging either to individual species and populations but also to the natural biological communities. It occurs when pollutions are discharged directly or indirectly into water bodies without adequate treatment to remove harmful constituents. Water pollution is major problem in the global context. It has been suggested that it is the leading worldwide cause of deaths and diseases, that in accounts for the deaths of more than 14,000 people daily. In addition to the acute problems of water pollution in developing countries continue to straggle with pollution problems as well. In the most recent national report on water quality in the Untied States, 45 % of assessed stream miles, 47 percent of assessed lake acres, and 32 percent of assessed bay and estuarine square miles were classified as polluted. Water is typically referred to as polluted when it is impaired by anthropogenic contaminants and either does not support a human use, like serving as drinking water, and/or undergoes a marked shift in its ability to support its constituent biotic communities, such as fish. Natural phenomena such as volcanoes, algae blooms, storms, earthquakes also cause major changes in water quality and the ecological status of water. Water pollution has many causes and characteristics.
