Understanding Water Pollution: The Impact Of Change

Water pollution is a global challenge that threatens the availability of clean water and endangers the health of millions of people around the world. It is caused by human activities such as industrialization and untreated wastewater being discharged into water bodies. Water pollution affects the ecosystem and causes various climatic changes, including rising surface temperatures, increasing and frequent flooding and droughts, and changes in the natural water ecosystem. The main water pollutants include bacteria, viruses, parasites, fertilisers, pesticides, pharmaceutical products, nitrates, phosphates, plastics, faecal waste, and radioactive substances. These substances do not always change the colour of the water, meaning they are often invisible pollutants.

Climate change can worsen water pollution

Water pollution is endangering the health of millions of people around the world. The World Health Organisation (WHO) defines polluted water as water whose composition has been changed to the extent that it is unusable. It is toxic water that cannot be drunk or used for essential purposes like agriculture, and which also causes diseases like diarrhoea, cholera, dysentery, typhoid and poliomyelitis that kill more than 500,000 people worldwide every year. The main water pollutants include bacteria, viruses, parasites, fertilisers, pesticides, pharmaceutical products, nitrates, phosphates, plastics, faecal waste and even radioactive substances.

Water pollution is endangering the health of millions of people around the world. The availability of clean water is greatly threatened by various human activities and of interest is pollution which in turn affects the ecosystem and causes various climatic changes. Water pollution poses a great threat to humans and the aquatic ecosystem while marked population increase catalyses climatic changes. The planet keeps nudging us with increasingly extreme droughts, reminding us that water is life. It is an essential resource upon which all living beings depend and it is crucial to all social and economic development, as well as energy production and adaptation to climate change.

The activities of increasing and frequent flooding and droughts and the changes in our natural water ecosystem are other areas of great concern in the continuous existence of man on Earth. According to WHO Geneva Report [66], climax situation and activities affect human well-being both directly and indirectly. The direct influence is through the physical effects of climatic extremes, whereas the indirect means include the influence on the intensities or level of pollution in the air, on the marine and freshwater systems that provide food and water, as well as the pathogens that cause infectious diseases.

Industrialization, in any society, is a major initiator of development and urbanization. Although the merits of industrialization are innumerable, it has been identified as a major threat to the environment as it releases various toxic chemicals, gases, solid wastes as well as microbes of various kinds into our immediate environment—land, air, and water. Of particular interest is water pollution, which has become a global challenge, developing nations being highly affected due to their drive for development. Pollution of our water bodies poses a great threat to humans and the aquatic ecosystem while marked population increase catalyses climatic changes.

Water pollution is endangering the health of millions of people around the world. The waters of the River Ganges flow clear and clean through the Indian city of Rishikesh at the gateway to the Himalayas.

Runoff can strip nutrients and pollutants from soil

Water pollution is a global challenge that has become a major threat to the environment and human health. It is caused by the release of toxic chemicals, gases, solid wastes, and microbes into the land, air, and water. Water pollution is endangering the health of millions of people around the world and is greatly threatened by various human activities.

Runoff is a significant contributor to water pollution. It can strip nutrients and pollutants from the soil and carry them into water bodies, such as rivers, seas, oceans, canals, lakes, and reservoirs. This can lead to increased levels of pollution in the air, on the marine and freshwater systems that provide food and water, and on the pathogens that cause infectious diseases.

The main water pollutants include bacteria, viruses, parasites, fertilisers, pesticides, pharmaceutical products, nitrates, phosphates, plastics, faecal waste, and even radioactive substances. These substances do not always change the colour of the water, meaning that they are often invisible pollutants.

The World Health Organisation (WHO) says that polluted water is water whose composition has been changed to the extent that it is unusable. In other words, it is toxic water that cannot be drunk or used for essential purposes like agriculture, and which also causes diseases like diarrhoea, cholera, dysentery, typhoid, and poliomyelitis that kill more than 500,000 people worldwide every year.

To ameliorate water pollution, it is essential to implement effective environmental protection policies and comply with these policies. This will help to reduce the release of toxic chemicals, gases, solid wastes, and microbes into the land, air, and water and protect human health and the environment.

Sediment and contaminants can harm fish and wildlife

Water pollution is a global challenge that has become a major threat to the environment and human health. It is caused by the release of toxic chemicals, gases, solid wastes, and microbes into the water bodies by industrial activities and untreated wastewater being discharged into the water bodies. Water pollution has adverse effects on the ecosystem and causes various climatic changes.

Sediment and contaminants can also disrupt the food chain in aquatic ecosystems. Toxic chemicals and gases can accumulate in the tissues of fish and other aquatic animals, making them toxic to predators and disrupting the natural balance of the ecosystem.

Furthermore, sediment and contaminants can damage the physical structures of fish and wildlife habitats. Sedimentation can bury fish eggs and young fish, preventing them from reaching maturity and reproducing. Contaminants can also damage the gills and other organs of fish, making them more susceptible to disease and reducing their overall health.

In conclusion, sediment and contaminants can have devastating effects on fish and wildlife, leading to population decline, disrupted food chains, and damaged habitats. It is essential to address the root causes of water pollution and implement effective environmental protection policies to mitigate the harm caused to fish and wildlife.

Deteriorating water quality can damage the global economy

Climate change is a major cause of deteriorating water quality. Heavier rainstorms will also increase surface runoff — the water that flows over the ground after a storm. This moving water may strip nutrients from the soil and pick up pollutants, dirt, and other undesirables, flushing them into nearby bodies of water. Those contaminants may muck up our water supplies and make it more expensive to clean the water to drinking standards. The National Climate Assessment finds that water quality is already diminishing in many parts of the U.S, “particularly due to increasing sediment and contaminant concentrations after heavy downpours.”

Deteriorating water quality is damaging the environment, health conditions and the global economy. The president of the World Bank, David Malpass, warns of the economic impact: "Deteriorating water quality is stalling economic growth and exacerbating poverty in many countries". The explanation is that, when biological oxygen demand — the indicator that measures the organic pollution found in water — exceeds a certain threshold, the growth in the Gross Domestic Product (GDP) of the regions within the associated water basins falls by a third.

Water pollution depletes aquatic ecosystems and triggers unbridled proliferation of phytoplankton in lakes — eutrophication —. The World Health Organisation (WHO) says that polluted water is water whose composition has been changed to the extent that it is unusable. In other words, it is toxic water that cannot be drunk or used for essential purposes like agriculture, and which also causes diseases like diarrhoea, cholera, dysentery, typhoid and poliomyelitis that kill more than 500,000 people worldwide every year. The main water pollutants include bacteria, viruses, parasites, fertilisers, pesticides, pharmaceutical products, nitrates, phosphates, plastics, faecal waste and even radioactive substances.

Climate change can affect the ability to maintain source water quality as well as the water quality conditions of surrounding rivers, lakes, and streams. An increase in stormwater runoff can degrade water quality and worsen existing pollution problems. Higher air temperatures, and the corresponding increase in water temperatures, can also promote increased growth of algae and microbes in some waterbodies. An increase in Harmful Algal Blooms (HABs) can threaten the availability of source water and increase the need for drinking water treatment.

An increase in water pollution can also damage the global economy by destroying biodiversity. Water pollution depletes aquatic ecosystems and triggers unbridled proliferation of phytoplankton in lakes — eutrophication —.
