“Light Pollution” is a form of environmental pollution in which excessive artificial outdoor lightings affect the natural environment. Light pollution in Hong Kong is very serious. The main reason behind that are the artificial outdoor lightings. As there are many buildings scattered in Hong Kong‚ artificial lighting is omnipresent. The severe light pollution reduces the number of stars that are visible in the sky. The HKSAR Electrical and Mechanical Services Department‚ 20% of the total electrical

Causes and Effects of Water Pollution Public Service Announcement for Pollution What are the causes of water pollution? This question has no simple answer. Water pollution can be defined as anything humans do to cause harmful effects to our bodies of water. This can include pollution of rivers‚ lakes‚ oceans‚ and ground water pollution. The causes of pollution in the water are virtually endless. Manufacturing plants are major causes of water pollution‚ using bodies of fresh water to carry away

Air pollution is the introduction of chemicals‚ particulates‚ biological materials‚ or other harmful materials into the Earth’s atmosphere‚ possibly causing disease‚ death to humans‚ damage to other living organisms such as food crops‚ or the natural or built environment. The atmosphere is a complex natural gaseous system that is essential to support life on planet Earth. Stratospheric ozone depletion due to air pollution has long been recognized as a threat to human health as well as to the Earth’s

SOUND POLLUTION NOISE CONTROL Noise has the potential to impact on us all every day‚ in different ways. Any form of noise can be considered pollution if it causes annoyance‚ sleeplessness‚ fright‚ or any other stress reaction. noise is transient; once it stops‚ the environment is free of it we can measure individual sounds that may damage human hearing‚ but it is difficult to monitor cumulative exposure to noise or to determine just how much is too much the definition of noise itself is highly

Environmental Pollution at Hindustan Lever’s Kodaikanal Plant In mid-2004‚ Hindustan Lever Ltd (HLL) executives looked back at the events of the past three years at their mercury thermometer factory in Kodaikanal in the south Indian state of Tamil Nadu. After mercury leakage from the plant had been reported in March 2001‚ heavy expenditure had been incurred in environmental risk assessment‚ waste disposal and health monitoring. The expenditure had exceeded the total profits generated by the plant

Pollution and Society *By Osanyinpeju* Aisha We all know that pollution in our world effects two essential aspects of our planet: air and water. Although their pollutants are emitted in completely different ways‚ they both harm living organisms. Air pollution is predominately emitted though the exhaust of motor vehicles and the combustion of fossil fuels‚ whereas water pollution is the result of industrial waste and environmental accidents. Our society knows that pollution is harmful and a serious

Air Pollution * Pollutants enter the air from various sources‚ but burning of fossil fuels contributes the most to air pollution. * Exhaust fumes from vehicles contains soot (tiny carbon particles)‚ lead (from cars using unleaded petrol)‚ carbon monoxide‚ oxides of nitrogen and hydrocarbons due to the incomplete combustion of fossil fuels. * Burning of fossil fuels in the combustion engines of vehicles and electrical power stations also releases large amount of carbon dioxide into the
