🗣️ English Goal

Explain causes, effects, and connected systems clearly using precise and practical language.

🌱 Sustainability Goal

Understand how complex sustainability problems involve interconnected causes and effects within systems and how clear explanation aids communication.

💭 Warm-Up Question

Can you describe one environmental problem in your town or city?

📖 Short Reading

Complex sustainability problems often involve many causes and effects connected in systems. For example, deforestation can start because farmers need more land for crops. This action reduces tree cover, which then affects the local climate. Trees help absorb carbon dioxide, so fewer trees mean more carbon remains in the air, contributing to climate change. Climate change can cause longer droughts or heavier rains, which harm farming and wildlife. Additionally, deforestation can cause soil erosion. Without trees to hold the soil, rain washes it away, reducing land fertility and increasing water pollution. These effects are all linked, creating a system where one change causes others. Understanding this system helps people find solutions. For instance, promoting sustainable farming can reduce forest loss while keeping food production. It can also involve reforestation, planting trees to restore damaged areas. Explaining these causes and effects clearly helps communities and decision-makers work together to solve problems more effectively.

📚 Key Vocabulary

Word or phrase Simple meaning Example
interconnected things that are linked or connected with each other Cause and effect are interconnected in sustainability problems.
deforestation the process of cutting down or removing trees from an area Deforestation can lead to soil erosion and loss of animal habitats.
carbon dioxide absorption the process where trees take in carbon dioxide from the air Forests are important for carbon dioxide absorption and help slow climate change.
soil erosion the washing or blowing away of topsoil from land Soil erosion reduces farming land quality after deforestation.
sustainable farming growing crops or raising animals in a way that does not harm the environment Sustainable farming helps protect forests while producing food.
reforestation planting trees to replace forests that were cut down Reforestation can restore soil quality and local climate.
system a set of connected parts working together The water cycle is a natural system in the environment.
long-term impact the effect that happens over a long period Deforestation has a long-term impact on biodiversity.
trade-off a situation where gaining one thing means losing another There is often a trade-off between farming land and forest protection.
cause and effect one event (cause) that makes something else happen (effect) Pollution is a cause, and poor air quality is an effect.

💬 Dialogue

🙂 Alex: I think the problem with deforestation is very complex.

😀 Sam: Yes, one of the main issues is that farmers need more land.

🙂 Alex: This happens because population growth increases food demand.

😀 Sam: As a result, many forests are lost, affecting local climates.

🙂 Alex: On the one hand, farming supports communities, but on the other hand, it harms the environment.

😀 Sam: One way to address this is to promote sustainable farming methods.

🙂 Alex: It would be better to consider reforestation to restore damaged areas.

😀 Sam: Exactly, explaining these causes and effects clearly helps improve decision-making.

🧩 Mini Practice

Practice answering aloud.


Say: Deforestation causes many connected problems in the environment.


Say: This happens because farmers need more land for crops.


Say: As a result, soil erosion and climate change increase.


Say: One way to help is by promoting sustainable farming.


Ask: Can you explain one cause and one effect of a sustainability problem you know?


Say: Yes, for example, traffic causes air pollution, and the effect is poor air quality in cities.


Ask: What is one suggestion you can give to explain a complex problem clearly?


Say: I think it's important to use simple language and give examples people can understand.

🌿 Small Sustainability Action

Observe one local environmental issue and try to explain its causes and effects clearly to a friend or family member.
