In the case of flooding and overflowing rivers, where the water causing drifting in the destruction of many villages and towns, and the elimination of agricultural land and the destruction of crops. Therefore, this cause a severe shortage of food resources availability. For example, the famine in the continent of Europe during the fourteenth century, where it continued to rain for more than a year! In 1929(wekipedia,2009). Also a famine occurred in China claimed the lives of nearly two million people after the flood Hwang River.
Oil spills occur due to the release of the liquid petroleum hydrocarbon in the environment, especially in marine areas. This released oil floats over the surface of the body thus preventing the sunlight to pass through it and making it difficult for the plants and animals to survive below water level. The three main effects of oil spillage are listed below:- 1. Environmental Effects: First of these is the environmental effect. The animal life that lives in the water or near the shore is the ones most affected by the spill.
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 typically referred to as polluted when it is impaired by anthropogenic contaminants and either does not support a human use, such as drinking water, or undergoes a marked shift in its ability to support its constituent biotic communities, such as fish. Natural phenomena such as volcanoes, algae blooms, storms, and earthquakes also cause
Literature Review Water pollution Water pollution is the contamination of water bodies such as lakes, rivers, oceans, aquifers and groundwater that very often causes by human activities. Water pollution occurs when pollutants such as particles, chemicals or substances that make water contaminated, discharged directly or indirectly into water bodies without enough treatment to get rid of harmful compounds. Pollutants get into water mainly by human causes or factors. Water pollution can be a Point-source, Non Point-source, or transboundary in nature (EPA 2013). Point source pollution happens when the pollutants when one source such as factory disposal comes into contact with the water source.
Result would be and algal bloom. Alga can be very toxic to animals and can deplete water of oxygen suffocating fish. Pollutants will find a way into the wetlands from mines or processing plants, industrial areas and through accidental oil spills. Visitors to rivers and rock holes pollute wetlands by throwing rubbish in the water or swimming in there with lots of sun screen on or insect repellent on. These chemicals will wash off and affect the water as the substances can be harmful and could reduce the water quality.
It was estimated that 215 patients in Louisiana died in hospitals and nursing homes due to the loss of electricity. (Natural Disasters and Hospital Safety, n.d.) An example of unnatural disaster is nuclear incidents in Fukushima, Japan, that caused thousands of deaths. 2.8 SURROUNDINGS The surrounding of the hospital also affects the patients, such as spaces, lighting, colour, noise levels and smells. For example, a noisy environment affects the growth of premature babies, especially their brain. Artificial lighting also affects them.
Jared Snow Ms. Carrell English 1 AP 9/15/15 Water Contamination Water pollution is any chemical, physical, or biological change in the quality of water that has a harmful effect on any living thing that drinks it, uses it or lives in it. I have spent many hours of many days to research this topic to find out facts of water pollution and how to prevent it. According to Food and Water Watch there are over 780 million people all over the earth that are living without clean drinking water. Another fact is every 20 seconds a child under five years old dies from illnesses that are waterborne. There is a lot of information about water contamination, the main topics are, effects of the percentage of water contaminated, ways it gets contaminated, and what to do in the after-math.
Many impurities exist in dirty water like bacteria, viruses, and helminths which will give you diseases like tapeworm, E.coli, and Hepatitis A. These are the diseases killing so many people in developing countries without clean drinking water. Unfortunately for these people, water is so important for the human body that they have to drink the water or they’ll die. For example Kenya has 44 million people. 18 million or 43% are without clean drinking water.
