Thesis Statement:
Water pollution is bringing down the economy, destroys the beauty of nature, and causing harmful dreaded diseases and sickness in precious health of many individual.

INTRODUCTION

Water pollution progresses every day in our lakes, oceans, rivers, and other bodies of water that we see and use in many ways. Water is essential for all living things to survive, yet people still pollute it. It's pretty sad to be taking a trip to the beach with your family and you get there to see a sign that says the beach is closed. Or not being able to eat a fish because it's diseased from pollution. Not all pollution is deliberate though, the definition of marine pollution according to the Group of Experts on the Scientific Aspects of Marine Pollution (GESAMP), is "Introduction of man, directly or indirectly, of substance or energy into the marine environment resulting in such deleterious effects as a harm to living resources, hazard to human health, hindrance to marine activities...impairment of quality for use of sea-water, and reduction of amenities" (Michaels). There are many natural causes for pollution too. The big causes for marine pollution are oil spills, erosion, and sewage, industrial waste

Statement of the Problem

1.What is Water Pollution?

2.What are the cause and effects of water pollution?

3. What can you do to prevent water pollution?

Body of the research
Water pollution has been seriously affecting the life of humans, plants as well as animals. The eco-system of rivers, streams, lakes, seas and oceans is also getting deteriorated due to the contamination of water, through various sources. This condition also leads to the outbreak of numerous diseases, majority of them being lethal and contagious. However, before going about finding a solution to the problem, we need to look into its underlying causes. In the following lines, we have provided information on the causes and harmful effects of water pollution. Go through them and then decide on your course of action.

Water Pollution Causes
The specific contaminants leading to pollution in water include a wide spectrum of chemicals, pathogens, and physical or sensory changes such as elevated temperature and discoloration. While many of the chemicals and substances that are regulated may be naturally occurring (calcium, sodium, iron, manganese, etc.) the concentration is often the key in determining what is a natural component of water, and what is a contaminant. Oxygen-depleting substances may be natural materials, such as plant matter (e.g. leaves and grass) as well as man-made chemicals. Other natural and anthropogenic substances may cause turbidity (cloudiness) which blocks light and disrupts plant growth, and clogs the gills of some fish species.[10] Many of the chemical substances are toxic. Pathogens can produce waterborne diseases in either human or animal hosts. Alteration of water's physical chemistry includes acidity (change in pH), electrical conductivity, temperature, and eutrophication. Eutrophication is an increase in the concentration of chemical nutrients in an ecosystem to an extent that increases in the primary productivity of the ecosystem. Depending on the degree of eutrophication, subsequent negative environmental effects such as anoxia (oxygen depletion) and severe reductions in water quality may occur, affecting fish and other animal populations. Pathogens

Coliform bacteria are a commonly-used bacterial indicator of water pollution, although not an actual cause of disease. Other microorganisms sometimes found in surface waters which have caused human health problems include: •Burkholderia pseudomallei

Cryptosporidium parvum
Giardia lamblia
Salmonella
Novovirus and other viruses
Parasitic worms (helminths).
High levels of pathogens may result from inadequately treated sewage discharges.[13] This can be caused by a sewage plant designed with less than secondary treatment (more typical in...
