The River

Rivers, the lifelines of civilizations, have been an integral part of human existence. From quenching our thirst to providing resources for various activities, rivers play a crucial role. In this blog on class 4 EVS chapter 13 – a River’s Tale, we will explore the journey of a river, from its pristine beginnings to its polluted stretches, discussing the causes, impacts, and possible solutions to the challenges it faces. This journey, as depicted in the NCERT Class 4 EVS Chapter “A River’s Tale,” sheds light on how human activities transform a clean, flowing river into a polluted water body. Let’s dive into this tale and understand the interconnectedness between rivers and human life.

The River’s Journey: A Story of Transformation

A River’s Tale starts from the origination of a river. The river starts as a clear, blue water body teeming with life. Fish, water plants, and other aquatic organisms thrive in its clean waters. As the river flows through different terrains and human settlements, its appearance and quality start changing. The transformation of the river is driven by various human activities, some beneficial but many harmful.

Imagine the story of a river that begins its journey in the mountains, where its waters are crystal clear. As it flows through the village, it becomes a source of life for the villagers. They use it for drinking, fishing, washing clothes, and watering their crops. The river supports the local wildlife, from birds to fish, and the surrounding flora.

However, as the river flows into the city, things begin to change. The once-clear water turns murky, the air around it smells foul, and the sight of waste and oil floating on its surface becomes more common. Big ships, factories, and the washing of clothes and animals introduce pollutants into the river. The riverbanks, once green and lively, now bear the brunt of human interference. Despite the changes, the river continues its journey, eventually flowing into the sea, carrying along the remnants of both its natural beauty and the pollution it gathered along the way.

Observing the River’s Changing Face

What is the Color of the River at Different Places?

When the river begins its journey, its color is often a clear blue, reflecting its purity. As stated in the chapter “A River’s Tale”, as it travels through different regions, its color changes.

• In the village, the water may remain relatively clean, with minimal human impact.
• However, as the river reaches industrial areas and cities, the color changes, sometimes turning brown or black due to pollutants such as industrial waste, sewage, and chemicals.

This color change is a clear indicator of pollution. The darker the water, the more contaminated it becomes.

The Fish Population: A Declining Trend

As further mentioned in the chapter “A River’s Tale” ” in some places in the river, there are many fish, while in others, there are only a few, and in some areas, dead fish are floating on the surface. This stark contrast can be attributed to several factors:

• Healthy Sections: Where the water is clean, fish thrive in large numbers. These areas provide the necessary oxygen and nutrients for aquatic life.
• Polluted Sections: In areas with high levels of pollution, fish populations decline sharply. The water lacks oxygen, and harmful chemicals poison the aquatic life, leading to the death of fish.

Changes Before the River Reaches the Village

Before the river reaches the village, it is relatively clean, flowing through natural landscapes. It might pass through forests or hilly areas where there is little to no human intervention. However, as it nears human settlements, signs of pollution start appearing. Washing of clothes, bathing of animals, and dumping of waste are common activities that affect the quality of the water.

Places of Concern: Where Would You Like to Live?

Looking at the different places along the river, one would likely prefer to live in areas where the river is still clean and unpolluted. These regions offer a healthier environment, free from foul smells and pollutants. Living near a polluted stretch of the river, on the other hand, can be detrimental to both health and the environment.

If given the chance, most of us would want to change the polluted sections of the river, making efforts to clean the water, control waste dumping, and ensure sustainable usage of river resources.

Keeping Rivers Clean: A Collective Responsibility

Observations from the Activity

In the suggested activity, children are asked to mix various substances like sugar, salt, haldi (turmeric), soap water, and oil in water to observe their behavior. Some substances dissolve easily, while others, like oil, float on the surface. This simple experiment helps demonstrate how pollutants like oil and industrial waste do not dissolve in water but instead create layers of contamination.

Here’s a table summarizing the observations:

What Can Be Done?

The chapter River’s Tale mentions that To keep rivers clean, both individual and collective actions are necessary. Here are a few ideas:

• Proper Waste Disposal: Avoid throwing garbage, plastic, and non-biodegradable items into rivers and water bodies.
• Treatment of Industrial Waste: Industries should ensure that their waste is properly treated before being released into rivers.
• Community Initiatives: Organizing regular cleaning drives and educating people about the importance of keeping rivers clean can make a significant impact.

Seasonal Changes in Water Bodies

Water bodies like rivers, ponds, and lakes undergo various changes throughout the year. During the rainy season, rivers swell with water, sometimes leading to floods. In contrast, during summers, water levels recede, and in some cases, the riverbeds might even dry up. These seasonal fluctuations also affect the kinds of aquatic life and vegetation around water bodies.
