Artificial light is an important factor that contributes effectively in the process of socio-economic development. And in fact, the industrial society has been too dependent on artificial light because it is used to illuminate public places, offices, factories, residential areas ... to meet and serve activities. However, when light is not used effectively, causing excessive light is the cause of pollution. light.Based on the characteriss of the sources and the object affected, light pollution is classified into the following categories: light intrusion, light abuse, glare, mess and light. usurp the sky.
Intrusion light occurs when light reflects on unwanted or unwanted areas. Such as street lights shining into the windows of roadside apartments, the result could be insomnia for those who live in them.Bright light is the result of the opposite of the light and dark areas in the view. When bright light is shining directly into the eyes of pedestrians will lose visibility in the night and this problem is especially serious for traffic safety.
Light abuse is excessive use of light, causing waste. The main cause of this problem is not turning off the light when not needed or inappropriate lighting design makes the use of light larger than necessary or the light does not focus on the necessary area.The light is cluttered due to the excessive use of multiple light sources. At the same time, they are arranged to create interwoven light streams. Typically, there are too many advertising lights on the streets. This is also a cause for pedestrians to easily lose focus and can lead to accidents.
Light appropriating the sky usually occurs in densely populated areas, especially in modern urban areas. All the light from different sources reflects off the night sky, causing the area to shine brightly when viewed from afar. This problem especially affects astronomers when observing stars.

Water Pollution is the contamination of water bodies. It occurs as a result of introduction of pollutants in water. Water is life. Still, we contribute in polluting the water bodies in several ways.

Water Pollution is mainly caused as a result of improper discharge of household and industrial chemicals wastes into the water bodies.

These dangerous chemicals (in the form of solid, liquid or gases) mixes with water and make it unsafe for living bodies. Water pollutants cause harm to human-beings, animals, trees and other constituents of environment.

Air pollution is a major change in the composition of the atmosphere, mainly from smoke, dust, soot, steam or air makes strange gas is not clean, there was a smell coming, reduced visibility, caused climate change, pathogenic for humans and creatures.

Air pollution caused more than 3 million people die prematurely every year, it threatens virtually all of the big city dwellers in the developing countries. According to Fox News 80% of cities in the world can not meet the standards of the World Health Organization (WHO) on air quality, which is mainly concentrated in poor countries. WHO said the level of urban air pollution worldwide has increased by 8% despite improvements in some areas. This leads to the risk of stroke, heart disease, lung cancer and a variety of respiratory problems.

     Water pollution is a phenomenon where rivers, lakes, seas and groundwater are contaminated with toxic substances in plant protection drugs, industrial wastes, domestic wastes, etc. great fruit to the lives of humans and natural creatures. There are many causes of water pollution, be it heavy rain, melting snow, storm winds, floods that accidentally bring a dirty amount of waste, dead organisms into the water environment, or volcanic eruption, sea level rise. However, human is the main factor leading to water pollution through industrial, domestic, agricultural, ... wastes into the water environment. We all know that just a sheet of paper, a carton of milk or a plastic bag is discharged into the pond environment, causing water pollution, landscape loss, and pipeline congestion. In addition, factories and enterprises are increasingly developing to serve the needs of production and consumption of people, making the source of wastewater soak up into the groundwater, causing serious water pollution. The consequences are very large, you probably do not know, up to 70% of the human body is water. People need clean water to serve daily activities. However, with the current situation of water pollution, human is the agent and can "RECEIVE DAY" is real. Because, the consequences of water pollution are huge: heavy metal contamination; Contamination of toxic organic compounds, pathogenic bacteria in water, especially wastewater. In order to effectively deal with water pollution, these solutions need to be formulated and implemented at all levels, from global, national to local. Hope you will join hands to overcome and keep the water source clean.

Water pollution is the pollution of bodies of water, such as lakes, rivers, seas, the oceans, as well as groudwater. It occurs when pollutants reach these bodies of water, without treatment. Waste from homes, factories and other buildings get into the water bodies.

Water pollution is a problem for the species and ecosystems there. It affects plants and organisms living in the water. In almost all cases the effect is damaging not only to individual species and populations, but also to the wider biological communities. The color is usually green or brown but normal water can be blue.

Agriculture is one of the major sources of water pollution, because the fertilizers given to the crops for better growth are washed into rivers and lakes, which in large amounts pollute the water.

There are many chemicals that are naturally found in these bodies of water but today it is polluted by nitrates, phosphates, oil, acid from acid rain, and debris like sediments, fallen logs and so on.

Loud speakers not only disturb the student in their studies but also the peace of locality. It may cause deafness, stress and high-blood pressure.

Effect on Animal Health: Animals suffer badly due to noise pollution. At times, it can also lead to death. Noise has impact on the living pattern of the animals and it may push the rare species to extinction. Like humans, they also suffer from temporary or permanent disability of hearing.

Protection: Personal protection against noise can be achieved by covering our ears with a cap, turban or even by spreading out the palms of our hands in excessive noise situations.

Solution: Legislation and public co-operation are essential to check noise pollution. Nobody should be permitted to create noise in silent zones. Noise-producing traffic vehicles should be prevented from plying on the roads. Crackers that create extremely disturbing sound should be discouraged. Standards for noise control measures should be set up for industry and community. The existing ordinances and acts against dangerous form of environmental pollution should be revised from time to time depending upon the changing nature of the sources.
