Professor: Let's turn our attention to a key concept in environmental science: ecosystem services. This term refers to the many and varied benefits that humans freely gain from the natural environment and from properly-functioning ecosystems. For a clear example, think about forests. They provide timber, but they also purify the air we breathe and regulate water flow. These are vital services. Understanding this concept is crucial because it helps us assign an economic value to conservation, making a stronger case for protecting our natural world.
