Lately, the automobile industry has been trying to switch from incomplete combustion to complete combustion as it is not dangerous and the products given off are less harmful. Nowadays, cars are being equipped with features such as cruise control which can reduce fuel consumption up to 6%. Scientists are trying to improve the cars performance and efficiency with fuel, They do this by creating engines which require less fuel to power the car. A high amount of waste energy is also made during the combustion of petroleum. This energy which is not helpful for the car which is lost is mainly heat and noise.
Pollution is the cause of many health risks to both humans and animals and is continuing to spread. Each type of pollution comes in various forms and has many effects, all of which can cause harm to the environment and the people who live in it. As long as humans are on Earth there will be pollution, but the actions one makes every day have the ability to drastically reduce the
Definition: of air pollution: Known as the World Health Organization experts that air pollution situation where the air outside the premises containing materials in concentrations considered harmful to humans or the components of the environment. it is intended to air pollution contaminated or contains several contaminants in quantities influential, and for a period of time may have an impact on human health, animal or plant, or the biosphere in which man lives. The polluted air if there is a change in the composition for any reason, and if mixed with some impurities or other gases by may harm life. air pollution :Is the existence of any material solid, liquid or gaseous air quantities lead to vital physiological or economic or human beings, animals and plants, machinery and equipment damage, or adversely affect the nature of things. The European Council knew air pollution thus: "There are said to be polluted in the air as strange or a significant change in the proportion of elements occur material appears to result in adverse result or to create disease or
There are many problems that society faces and one problem, such as air pollution threatens societies and entire world. Air pollution is the contamination of air with pollutants that are harmful to humans, animals, and the environment. It began to be a problem when humans discovered the uses of fire and then the amount of air pollution exponentially grew after the industrial revolution, and is still a problem even today. The largest causes of air pollution are from human activities such as burning of fossils fuels and manufacturing plants. There are ways that ordinary people can help contribute to prevent air pollution and its consequences that the world must face.
For almost a century with the rapid growth of technology, the increasing pressure from population and the development of heavy industry, air pollution has become the extreme serious problem in the whole world. Slanina (2013) states that due to the chemical waste gases from factory and vehicle emission from traffic pollution, which not only bring negative effects to the public it also reduce the living quality and air quality. In this day and age, the problem of air pollution has aroused public’s concern, especially in several developing countries such as China, India and South Africa. This essay will discuss the adverse effects of air pollution and give some potential solutions about
Agricultural activities: human beings rely on agriculture for food. However, certain agricultural activities like spraying of chemicals to get rid of parasites may end up causing pollution to the air. Poor waste disposal: poor waste disposal is regarded as one of the major causes of pollution because it is widely practiced. Both industries and individual human beings contribute to this cause. Industrial Emissions: in the process of creating products to be used for various issues, industries end up emitting large quantities of toxic wastes and fumes which end up causing pollution.
Several efforts have been made over recent years to maintain a safe and clean environment. However, environmental pollution is getting worst and poses a major threat to the Earth. Environmental pollution is “the contamination of the physical and biological components of the Earth to such an extent that normal environmental processes are adversely affected” (Kemp, 1998, p. 129). There are five known pollution which is in the form of air, water, land, noise and light (refer to Figure 1 in Appendix 1). The first type of pollution is air pollution.
 proposed an axisymmetric model and also included plastic deformation heat. They studied the temperature and stress distribution and found that the peak temperature develops at the center of weld interface. Kim, et al.  proposed a 3-D thermo-mechanical analysis of an ultrasonic spot welding
Pollution is the introduction of contaminants into a natural environment that causes instability, disorder, harm or discomfort to the ecosystem (Botkin; 2014). There are four types of pollution which are, air, water, land and noise pollution. Pollutants are the elements of
These sources are equally responsible for pollution as the stationary sources. Ex: Vehicles, ships, railways, etc. • Controlled burning: Controlled burning of forests to clear land for agriculture causes intense pollution. Also this adds to the negative effects by causing deforestation, which has its own related hazards. • Waste Disposal: Waste disposal on land produces a polluting gas called methane.
