Negative effects of cars

Negative effects of cars

Cars emit the greenhouse gasses such as carbon dioxide which contribute to global warming, Some air pollutants and particulate matters from the cars can be deposited on the soil and the water surface where they enter the food chain that can affect the reproductive, respiratory, the immune and the neurological systems of animals.

Lead is a pollutant that produced from burning leaded fuel, interferes with normal red blood cell creation by reducing important enzymes in the body, Lead damages the red blood cell membranes and it obstructs the cell metabolism, it shortens the lifespan of each individual cell and all of these harmful effects can cause Anemia.

The cars are very expensive, The car exhaust causes chemical pollution for the air & it causes chest & eye diseases, It causes respiratory distress especially in children, elderly people and those who suffer from respiratory diseases.

The exhaust fumes from the engines of cars contain a number of polluting substances such as carbon monoxide and a variety of complex hydrocarbons, Nitrogen oxides and sulfur oxides that cause the acid rain which changes the pH of the waterways & the soils and they can harm the organisms that rely on these resources.

The cars cause two types of pollution discharged which are the exhaust emissions & evaporative emissions, the exhaust emissions include dangerous gases such as carbon monoxide, oxides of nitrogen, hydrocarbons & particulates, The evaporative emissions are the vapors of fuel which are released into the atmosphere without being burnt.

They release the chemicals into the environment that cause severe harm to the human as well as the animals, They burn the nonrenewable fossil fuels, So, they cause pollution which leads to acid rain that can harm both the humans & the environment.

Benzene is one of the pollutants released by cars, It has been linked to lowered immunity and leukemia, The pollutants from car exhaust can also cause coughing and breathing difficulties.

The cars cause smoke which increases the quantity of certain toxic chemicals discharged by the vehicles into the air, the toxic chemicals from the cars can cause severe irritation to the eyes, the nose, the throat, and the lungs, They can also be absorbed into the body and they cause the deterioration in general health.

        I agreed that cars are use full… But only when they are used in the correct way and limited time…
        Else oxygen is more important than cars… And how can we compromise humans health and life over the car’s… We really need to think… People should take it serious… Else nature will take it.. And believe me that will not good for us…
