Ecosystem Services: Key Concepts and Applications

The video covers ecosystem services, which are benefits humans derive from ecosystems, categorized into provisioning, regulating, supporting, and cultural services. It explains how these services have economic value and how human activities like deforestation and overfishing can disrupt them, leading to ecological and economic consequences. The video concludes with examples and practice questions to reinforce learning.

What is the main objective of learning about ecosystem services?

• To study the biodiversity of different ecosystems.

• To learn about the history of ecosystems.

• To describe ecosystem services and how humans can disrupt them.

• To understand how ecosystems function independently of humans.
