DEFORESTATION AND OVER-HUNTING | MATRIC PART 1 BIOLOGY CHAPTER 3 | 9TH BIOLOGY URDU LECTURE (LECTURE NO 9)

Welcome to Munir Science Academy! In today's video, we explore the critical topics of *deforestation and over-hunting**, which have devastating impacts on our environment and **biodiversity**. **Deforestation* means the *cutting down of trees* and the *conversion of a forest* into non-forest areas, leading to the loss of *significant areas of forest* and contributing to a **degraded environment**.

We’ll dive into the *causes and effects of deforestation**, which often result from the deliberate **removal of forests* for *wood* and other economic activities. This process contributes to *forest degradation* and disrupts the *amount of water in the soil and moisture in the atmosphere**, increasing the **chances of soil erosion**. **Heavy rainfall washes away essential nutrients* from the soil, leading to the buildup of *mud and silt* in rivers and dams, reducing their **water storage capacity**.

Deforestation also leads to *decreased transpiration**, which reduces the sources of rainfall. The loss of forests harms **biodiversity* and has a direct impact on *human societies**. **Forests extract carbon dioxide* and other pollutants from the air, and without them, the environment and human health suffer.

In regions like *Khyber Pakhtunkhwa**, **canopy forests* are shrinking rapidly, becoming a *significant cause of the extinction of hundreds of species**. Deforestation is a **principal threat* to wildlife and ecosystems across the globe.

This video is an essential resource for students studying *9th Biology in Urdu**. Whether you're learning about the **Fundamentals of biology* or preparing for your *Matric part 1 biology chapter 1**, this lecture will provide you with a deeper understanding of the consequences of **deforestation* and its impact on our planet.
