Chapter: 18. The Environment

⁠

Question 1

⁠

What type of pollution is primarily depicted in this image?

List at least three sources or types of waste contributing to the pollution shown.

What are the potential harms of this pollution to living beings?

Answers

The image primarily depicts water pollution, as a river is shown to be contaminated with various forms of waste and murky discharge.

Three sources or types of waste contributing to the pollution include plastic bottles, discarded tires, and industrial waste flowing directly from a factory pipe into the river.

The potential harms of this pollution to living beings are significant; it makes the water unfit for drinking for humans and animals, harms aquatic animals and plants by making their habitat toxic, and can even affect groundwater quality.

Question 2

⁠

Which type of environmental pollution is prominently featured in this picture?

Identify two main human activities contributing to this type of pollution as seen in the image.

How does this pollution affect people’s health and the Earth’s temperature?

Answers

The type of environmental pollution prominently featured in this picture is air pollution, clearly visible as thick smog covering the city skyline.

Two main human activities contributing to this pollution are industrial activity, represented by dark smoke from factory chimneys, and transportation, shown by numerous cars on a busy road emitting exhaust fumes.

This pollution affects people’s health by making the air dirty and unfit for breathing, which can lead to various sicknesses. It also contributes to the Earth’s temperature increasing, as pollutants can trap heat in the atmosphere.

Question 3

⁠

What environmental action are the children performing in this picture?

How does this action help improve the environment?

Which of the 3 R’s of conservation is most closely related to the outcome of planting trees, and why?

Answers

The children in this picture are performing the environmental action of planting trees, specifically young saplings.

Planting trees helps improve the environment in several ways; they absorb carbon dioxide, a harmful gas, and release oxygen, thus making the air clean and fresh for breathing. They also help combat global warming by reducing the Earth’s temperature.

The outcome of planting trees is most closely related to ‘Reduce’. While not directly reducing waste, it reduces the amount of carbon dioxide in the atmosphere, thereby reducing the harmful impact of air pollution and helping to reduce the overall warming of the Earth.

Question 4

⁠

What environmental practice does this image encourage?

Which of the “3 R’s” of conservation is directly related to the purpose of this bin?

Why is it important to separate waste into different categories before disposal?

This image encourages the environmental practice of recycling, specifically by sorting waste into different categories.

The “3 R’s” of conservation that is directly related to the purpose of this bin is “Recycle.”

It is important to separate waste into different categories before disposal because it makes the recycling process more efficient. Different materials require different processing methods to be turned into new items, and separating them at the source ensures that they can be properly recycled rather than ending up in landfills.
