💡 6th Grade English (ELA): Human-Environment Interaction Practice Questions
1
Solved Example
Easy Level
Imagine a farmer planting crops in a new area. How might the farmer's decision to clear a forest for farmland change the environment?
Solution & Explanation
Step 1: Identify the human action. The farmer is clearing a forest.
Step 2: Consider the immediate environmental impact. Clearing a forest removes trees.
Step 3: Think about the consequences of removing trees. This could lead to soil erosion (soil washing away), loss of habitat for animals that lived in the forest, and fewer plants to absorb carbon dioxide from the air.
👉 The farmer's action directly impacts the natural environment by removing trees and potentially causing erosion and habitat loss.

Solved Example
Easy Level
A city builds a new dam on a river. What is one way this human action affects the environment downstream?
Solution & Explanation
Step 1: Identify the human action. Building a dam.
Step 2: Understand the function of a dam. Dams hold back water, creating a reservoir.
Step 3: Consider the effect on the river flow downstream. Less water will flow downstream.
💡 This can affect the plants and animals that rely on the river's natural flow, and it might also reduce the amount of sediment (tiny bits of rock and soil) that reaches areas downstream, which can be important for ecosystems.

Solved Example
Medium Level
People in a coastal town start using more plastic bags. How could this human activity lead to a negative impact on the ocean environment?
Solution & Explanation
Step 1: Identify the human activity. Increased use of plastic bags.
Step 2: Consider where the plastic bags might end up. If not disposed of properly, they can be blown by the wind or washed into storm drains.
Step 3: Trace the path to the ocean. Storm drains often lead to rivers, which then flow into the ocean.
Step 4: Think about the harm to marine life. Plastic bags can be mistaken for food by sea turtles and other animals, causing them to choke or starve. They can also break down into smaller pieces called microplastics, which pollute the water.
📌 The human choice to use more plastic bags, if not managed, can lead to significant ocean pollution and harm to marine life.

Solved Example
Medium Level
A community decides to plant many trees in a barren area. What is a positive environmental effect of this human action?
Solution & Explanation
Step 1: Identify the human action. Planting trees.
Step 2: Consider the benefits of trees. Trees absorb carbon dioxide (a greenhouse gas) and release oxygen.
Step 3: Think about the impact on the soil. Tree roots help hold the soil in place, reducing erosion.
Step 4: Consider the habitat. Trees provide shelter and food for various animals.
✅ Planting trees can improve air quality, prevent soil erosion, and create habitats for wildlife, all of which are positive environmental changes.

Solved Example
Medium Level
A large factory is built near a river. The factory releases warm water into the river as part of its cooling process. How might this human impact affect the fish living in the river?
Solution & Explanation
Step 1: Identify the human action and its direct effect. A factory releases warm water into the river.
Step 2: Consider the normal temperature of the river. Rivers have a specific temperature range that is comfortable for the fish living there.
Step 3: Think about the effect of warmer water on fish. Fish are sensitive to temperature changes. Warmer water can hold less dissolved oxygen, which fish need to breathe. It can also stress the fish, making them more vulnerable to diseases or unable to reproduce.
👉 This is an example of thermal pollution, where heat changes the natural environment and can harm aquatic life.

Solved Example
Medium Level
In a desert region, people build an irrigation system to bring water from a distant river to grow crops. While this helps the people, what is a potential environmental consequence of diverting so much water from the distant river?
Solution & Explanation
Step 1: Identify the human action. Diverting water using an irrigation system.
Step 2: Understand the source of the water. The water comes from a distant river.
Step 3: Consider the impact on the river's original environment. If a large amount of water is taken, the river's water level will decrease significantly.
Step 4: Think about the downstream effects. This can lead to less water flowing to ecosystems that depend on the river downstream, potentially harming plants, animals, and even other human communities that rely on that river. It can also affect the flow of sediment.
📌 This highlights how human needs can create environmental challenges in different locations, demonstrating a complex human-environment interaction.

Solved Example
Real World Example
When you throw away a plastic bottle instead of recycling it, how does this human choice contribute to the problem of pollution in landfills or oceans?
Solution & Explanation
Step 1: Identify the human choice. Not recycling a plastic bottle.
Step 2: Consider the destination of the bottle. It goes to a landfill or, if improperly disposed of, can end up in waterways and eventually the ocean.
Step 3: Think about the environmental impact of plastic. Plastic takes hundreds of years to decompose. In landfills, it takes up space. In oceans, it harms marine life and pollutes the water.
💡 Recycling is a way humans can reduce their negative impact on the environment by reusing materials and lessening the amount of waste.

Solved Example
Real World Example
Farmers often use fertilizers to help crops grow better. What is a way this agricultural practice can sometimes negatively affect nearby rivers or lakes?
Solution & Explanation
Step 1: Identify the human practice. Using fertilizers on crops.
Step 2: Consider how fertilizers are applied. They are spread on the soil.
Step 3: Think about what happens when it rains or when the land is watered. Rain or irrigation can wash excess fertilizer from the soil into nearby streams, rivers, or lakes.
Step 4: Understand the effect of excess fertilizer in water. This can cause too much growth of algae (a process called eutrophication), which then uses up the oxygen in the water, harming fish and other aquatic life.
👉 This is a common example of how human activities in agriculture can lead to water pollution if not managed carefully.
