Although China is the main concern, the air pollution throughout the world is also detrimental as “98% of cities in low- and middle-income countries with more than 100,000 inhabitants do not meet WHO air quality guidelines. However, in high-income countries, that percentage decreases to 56%” (“Air pollution,” 2016, para. 2). The reason that air pollution is extremely harmful is that of its increased risk of lung cancer, heart disease, stroke, and chronic and acute respiratory diseases, including
Water Pollution – a global scenario Even though 70% of the earth is covered with water, the availability of fresh water is very limited. Ponds, lakes, rivers, reservoirs, streams etc are the major fresh water sources we have and these sources are most likely to get polluted. According to UN water statistics ‘ By 2025, 1800 million people will be living in countries or regions with absolute water scarcity, and two-thirds of the world population could be under stress conditions’. The World Health Organization fact sheet says that • Dirty water kills more people than all kinds of violence including war. • Diarrhea kills more young children than AIDS, malaria and measles jointly and is the second leading cause of death among children under five
Water scarcity is lack of sufficient, clean, and safe water in a given region. This is very common as it affects every continent around the world and almost 2.8 billion people. Water scarcity often occurs and is a dominant isuue in the world since it threatens human health and economy. One of the main causes of water Scarcity is water pollution. Water pollution is the contamination of water due to unhealthy human activities.
Water is a major component of living matter and is essential for living. Diarrhea is estimated to cause 1.5 million deaths per year, mostly among children under five years old, living in developing countries. There were 2.7 billion people without access to basic sanitation in 2015 (World Health Organization, 2015). There are three types of natural waters or the waters that precipitated on the actual location already, namely the ground, the surface, and the deep-well waters, but because water dissolves the wastes and compounds in the soil, dissolved particles combine with the water that makes it not suitable for drinking and consuming. There are different techniques to purify water such as filtration, heating and the use of chemicals (halogens) to terminate the bacteria living on the water.
The industrial production of steel, cement, and brick are other major sources that account for 49% of Nitrogen Oxide in that region. According to Los Angeles Times, (Air pollution takes years 1) “People die 5.5 years earlier in northern China than in the south, and heavy air pollution is almost entirely to blame.” Not only is the air pollution awful, but the pollution levels in water are also unbearable. Factories around the world make their products, releasing their smog into the air and the nearby lakes, ponds, and bodies of water. In return thousands of aquatic wildlife are becoming endangered species daily. Chris Woodford (Water Pollution: an Introduction 1) explains “Each year, the world generates perhaps 5–10 billion tons of industrial waste, much of which is pumped untreated into rivers, oceans, and other waterways.” Radioactive wastes and oil spills affect the wildlife living in these areas in great ways.
In most of the countries is Asia such as china and Indonesia has had severe consequences because of water pollution. Over 320 million people in china do not have access to clean drinkable water due to water pollution. The main brands that are causing this pollution in mainly china and Indonesia are clothing brands such as Burberry, Disney and Adidas. Due to certain investigations done by Greenpeace a textile facility were dumping PH 14 water, hazardous and hormone disrupting chemicals straight into the local water supply. This is one of many factories in Indonesia that are using local water supplies like sewers for their chemical waste.
Water pollution refers to the changes in the physical, biological, chemical or thermal conditions of water body which harmfully disrupts the balance of ecosystem. Water pollution results when overwhelming amount of waste coming from different sources of pollutants such as effluent, litter, refuse sewage or contaminated runoff could no longer be accommodated by the natural ecosystem (WRC, 2000). The main sources of water pollution are agricultural activities, commercial and industrial discharges, domestic and municipal wastewater (Rashid, 2012). First of all, the agricultural intensification has been the origin of several harmful effects on the environment even if it allows covering the food needs of the population. The use of fertilizers and pesticides is considered to be the potential source of water pollution (FAO, 1978).
In view of the increasingly stringent environmental policy adopted by industrialized countries, a rising care has been directed to water pollution problem. Significant amounts of water are consumed during processing in many industries using dyes as textile, paper, plastic, leather, food and cosmetics industries. 1-15% of the dye is estimated to be lost in dyeing and finishing processes and are released into waste waters. About 10,000 dyes and pigments are used in the textile industry, most of themare toxic substances to humans and aquatic life; 50,000 tones of dyes are estimated to be discharged from dyeing and coloration industries One of the main sources of environmental contamination is the dye pollutants from these industries, the disposal of these colored waste waters is a threat to the environment [1-5]. Color bath effluents throw shading to the recieving streams.
It is estimated that about 1 billion people all around the world lack access to clean drinking water. Poor management of water resources has led to the degradation of water. In most cases poor people are the ones who suffer the consequences. It is reported that 80% of all illness in developing countries is related to unclean water and poor sanitation. It is estimated that more than 3 million people die every year due to infectious
The rivers in Selangor are highly vulnerable to pollution due to the government’s inefficient town and land-use planning and insufficient of supervision and enforcement by the various local authorities. Association of Water and Energy Research Malaysia (AWER) President, S.Piarapakaran blamed the government entirely because lack of enforcement.He added most of the pollutant came from the factories. Sungai Semenyih water treatment plant had to stop their operations because the level of ammonia and manganese in the water keep rising and last February, the reading of ammonia in the water exceeded the 1.5mg per litre standard that is set by the Health Ministry leads to the water cut off which affected about 22,000 households in the Hulu Langat and Kuala Langat areas. Piarapakaran said that existing law,Environment Quality Act 1974 and Water Services Industry Act 2006 should be enough to punish the wrongdoers if it is been enforced
