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 pollution is the contamination of water due to unhealthy human activities. The pollution is mostly caused by industrial waste, global warming, garbage and waste dumping, and oil leakage. According to waterbenefitshealth there are many types of water pollution such as “Surface water pollution, Groundwater pollution, Microbial pollution, Oxygen Depletion pollution, Nutrient pollution, Suspended Matter pollution, and Chemical pollution.” Water pollution is a hazardous case in the world as it leads to hunger, poverty, diseases, extinction of aquatic animals, and lack of human access to fresh water.
This lay way for Wang Mang’s unsuccessful Xin Dynasty. Partially because Wang Mang was faced with a natural catastrophe that destabilized the government socially and economically from the beginning of his reign (Lewis 2009). The natural catastrophe was the flood of the Yellow River. It altered the path for which water travelled through China and discharged into the sea. Channels that originally protected the people of China broke during the flood of the Yellow River and brought devastation upon the people (Chang-Qun et al.
Destruction of the rapids and dredging of the river channels will change the water flows, impacting people who live along the banks of the Mekong and have adapted to the river’s flood-drought cycle. Without the rapids, the river may flow faster, eroding the riverbanks and damaging riverside plantations. Government of China invests in this project to increase the shipping efficiency. When the Merchant ships are sail they will leave the refuse in the river. The second problem is the farmers use chemicals in agriculture.
Every manufacturing industry has its own unique operations as well as its challenges. The textile Industry has been one of the largest contributor to the water pollution in the world. Voluminous amount of water and chemicals go into the transformation process from greige goods to printed materials. Although other pollutants to the environment are also a concern, such as the solid waste and the air pollutants, water remains the largest and the most troubling. The new wave of Eco-Textile producers have coined the textile industry as the world’s worst offender in terms of pollution.
For example, dyeing houses in heavily populated countries, India and China are notorious for exhausting local water supplies. Synthetic dyes have a detrimental effect on all forms of life. They have chemicals that produce highly toxic wastewater. Interestingly, when this waste is mixed with some disinfectants, they can form by-products that are even worse e.g.
additional treatments to meet the standard quality for human consumption. For example, in 2000, the water quality of the river in terms of pH, aluminium, iron and manganese were reported to exceed the Malaysian standard for drinking water quality (Norris & Hawkins, 2000). These subsequently affected the normal operation of the water treatment plant and thus upset the normal supply of drinking water to the community. Pollution of this river by heavy metals is a serious problem, because many such pollutants are both highly toxic and not biodegradable in the natural environment (Morillo et al., 2002). Heavy metal contamination in aquatic and soil environments threatens aquatic ecosystems, agriculture and human health (Overesch et al., 2007).
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
