Bangladesh’s water crisis affects both rural and urban areas, and is a matter of both water scarcity and water quality. While Bangladesh has made commendable progress in supplying safe water to its people, gross disparity in coverage still exists across the country. Latrine usage is very poor, averaging only 16% in the rural areas. Diarrheal diseases constitute a major health problem in Bangladesh, killing over 100,000 children each year. Thousands of episodes of diarrhea occur in children and adults each day.
AIDS has major effects on the behaviour and eating habits. People that have the disease get mouth sores, they get really thin, and they contract a lot of other diseases, which in turn makes them very sick. Tuberculosis (TB) is quite unique among infections associated with HIV. It is easily treatable once identified and may occur in the early stages of the HIV disease. It is prevented with drug therapy.
Malunggay- (Moringa Oleifera), is a popular plant known for nutritional value as well as a herbal medicine. Malunggay is a plant that grows in the tropical climates such as the Philippines, India and Africa. Cockroach- are insects of the order Blattodea, sometimes called Blattaria, of which about 30 species out of 4,600 total are associated with human habitats. About four species are well known as pests. REVIEW OF RELATED LITERATURE Pesticide - The Pesticide is a broad term that refers to any device, method, or chemicals that kill plants or animals that compete for humanity’s food supply or are otherwise undesirable.
Water pollution affects humans’ well-being by creating infectious diseases. Sub-point: The author who wrote the book The Water We Drink, states that water pollution creates water-borne diseases infections such as cholera, typhoid and infectious diarrhea, which persists due to lack of clean water. He also states that over 1.5 billion people in the world do not have access to clean water and almost four million people die every year of a water related disease. Sub-point:
Waterborne diseases General InformationWater-borne diseases are any illness caused by drinking water contaminated by human or animal faeces, which contain pathogenic microorganisms. The full picture of water-associated diseases is complex for a number of reasons. Over the past decades, the picture of water-related human health issues has become increasingly comprehensive, with the emergence of new water-related infection diseases and the re-emergence of ones already known. Data are available for some water-, sanitation- and hygiene-related diseases (which include salmonellosis, cholera, shigellosis), but for others such malaria, schistosomiasis or the most modern infections such legionellosis or SARS CoV the analyses remain to be done. The burden of several disease groups can only partly be attributed to water determinants.
It has been observed that both humans as well as animals are daily contaminated by the heavy metals. The heavy metals like Hg and light metals like Al are poisoning us and animals every day in vaccines, from environmental pollution in air and water, and from the foods. Most heavy metals cause mental disorders, respiratory problems, hormonal imbalance and they are carcinogenic as well in human. That is why heavy metals remain a special concern especially in cases where the effluent city is an important factor. .
Waterborne diseases Waterborne diseases are caused by pathogenic microorganisms which are directly transmitted when contaminated fresh water is consumed. Contaminated fresh water, used in the preparation of food, can be the source of foodborne disease through consumption of the same microorganisms. According to the World Health Organization, diarrheal disease accounts for an estimated 4.1% of the total DALY global burden of disease and is responsible for the deaths of 1.8 million people every year. It was estimated that 88% of that burden is attributable to unsafe water supply, sanitation and hygiene, and is mostly concentrated in children in developing countries. Waterborne disease can be caused by protozoa, viruses, or bacteria, many of which are intestinal parasites.
The health dangers that the lack of clean water creates ranges in levels with the most severe being death. “More than 3.5 million people die each year from water-related disease; 84 percent are children. Nearly all deaths, 98 percent, occur in the developing world”.There are many waterborne diseases that contribute to poor health conditions. For example, “Diarrhoeal disease alone amounts to an estimated 4.1 % of the total DALY global burden of disease and is responsible for the deaths of 1.8 million
According to the United Nation World Water Assessment Program, it is about the human health impacts of water pollution, which is about 3.4 million people die due to the diseases related to water every year. The examples of diseases include dysentery, typhoid and cholera or others water-borne ailments such as malaria, yellow fever transmitted from mosquitoes that breed in the ditches with stagnant, dirty water. Besides that, medicaments and personal care product just like soap and lotions are found in the rivers and lakes. The studies found that the synthetic hormones in these products may damage natural hormones of aquatic animals like fish. Farmer often uses chemicals to prevent bug infestation or other diseases, damage or destroy their crops.
More than 600 million Chinese drink polluted water and 20 million people drink well water with high levels of radiation. China’s high rates of many sorts of cancer have been linked to water pollution. Ø Deforestation: Deforestation continues to be one of the biggest problems China is facing. Deforestation has a
