Water and Its Pollution

Kids, when we are very thirsty, there is nothing compared to a cool glass of water. Right? But have you ever wondered where this water comes from before it hits the drinking fountain, a faucet or your refrigerator?

Children Drinking Water

Seventy per cent of our earth’s surface is covered with water. But do you know that only a tiny portion of that seventy per cent of water is drinkable? Water is needed for all living things, and we use it daily. We drink it, wash with it, cool it off, and cook with it. 

What is Water?

We all know that without water, life is not possible on earth.  But children, have you ever thought about what water is exactly? We will study water and water pollution in this article.

Two chemicals, oxygen and hydrogen, make up water. Oxygen and Hydrogen are both gases, but when combined, they form a liquid- Water. It is why water is sometimes referred to as H2O. A water molecule is the same whether it is a solid, a  liquid or a gas. Water, in its liquid form, is what we drink. Water evaporates to form steam or vapour. When water gets cold enough, it freezes and becomes a solid, which we call ice.  Water can also become a gas when boiled and becomes hot, which is called water vapour.

Water Pollution

Let's know about some water pollution information for children:

Our bodies need fresh water to survive, and clean drinking water is essential for life on our planet. But in some parts of the world, people don’t have clean drinking water. Some people must travel long distances to get water and boil it or use special filters before they can drink it. The primary cause of this impure water is water pollution. Large pieces of the trash sometimes pollute the water we can see, or other times it is contaminated by invisible chemicals unseen by the naked eye.

Polluted water cannot be used for drinking because it contains chemicals or other germs which can make you sick. Water pollution is becoming a huge problem, so it is important to prevent it whenever possible.

Natural Causes of Water Pollution

Water pollution happens when different chemicals, particles, and other substances cause the water to become unsafe for human usage. There can be some natural causes of water pollution. The eruption of a volcano, silt from storms or a flood is some way water is naturally polluted. When mixed with dirty chemicals, rainwater makes its way to the ocean, rivers, lakes and streams.

Animal waste is also a big natural water pollutant. When any big marine animal dies, it causes contamination of that particular part of the water body, making it unfit for use. Aquatic weed found on water bodies depletes the oxygen dissociation of water bodies, thus causing marine death. Excessive growth of algal plants in the water body is also a big natural cause of water pollution. The sludge and mud which flows from river currents and their diversions are also one major factor causing water pollution naturally.

Facts About Water Pollution

Now, let's learn some facts about water pollution:

• Every year nearly seventeen billion pounds of plastic is dumped into the ocean and other water bodies. That is more plastic in the ocean than fish.

• Even though nearly seventy per cent of the earth is covered with water, only twenty-five per cent of that water is fit for the consumption of humans. Most of the water on our planet is the ocean.

• Over one billion people on our planet need clean drinking water resources.

• There are more human causes of water pollution than natural causes. Sewage, fertilisers and pesticides from farm waste, waste from factories and construction sites, and oil spillage from ships are some human-made causes of water pollution.

• Water pollution disrupts food chains. Smaller aquatic animals eat the chemical pollutants, and when larger fishes consume these animals, they die. This disrupts the aquatic food chain.

• Drinking unclean and polluted water can cause severe diseases and health problems. Polluted water contains many germs and pathogens which cause severe diseases in humans and other living beings.

Summary

Children, we all know that life on earth would not exist without water. The above article taught us how water is formed and water pollution information for children. We also read about the natural causes and facts about water pollution. Although it might not be possible for you to prevent all types of water pollution, there are lots of ways by which you can help keep the water clean where you live.

Fresh, clean water is a precious resource, so we can save it by reducing the water we use in showers or lawns. Also, recycling the garbage we generate can help reduce water pollution as it will not go directly to the water bodies. We hope you enjoyed reading this article; in case of any doubts, feel free to ask in the comments.
