Class 5 Evs - ICSE-SCIENCE
Environment and Conservation - Deforestation, Wildlife Protection, 3Rs
In this Class 5 EVS chapter, students explore the vital connection between human life and nature. We learn about deforestation and its harmful effects like global warming and loss of animal habitats. The chapter highlights the importance of wildlife protection through national parks and sanctuaries. Finally, it introduces the 3Rs—Reduce, Reuse, and Recycle—as practical daily steps to conserve our environment. Understanding these topics is crucial for ICSE Science board exams as they test environmental awareness, real-life application, and problem-solving skills through descriptive and application-based questions.

Frequently Asked Questions
What is the difference between afforestation and reforestation?
Afforestation is planting trees in an area where there were never any trees before, while reforestation is planting trees in a forest area that was destroyed by cutting.
How do the 3Rs help protect the environment?
The 3Rs reduce the amount of garbage we create, save natural resources like wood and water, and lower pollution levels on Earth.
Why are forests important for us?
Forests provide oxygen, give homes to wildlife, bring rain, and absorb harmful carbon dioxide from the air.
