Can humans build a forest, or can we only plant trees?

In this episode of The Climate Translation, Dr. Mac explores one of the largest ecological restoration projects in history: China's Great Green Wall. Stretching thousands of miles across northern China, this ambitious effort was designed to slow the spread of desertification, reduce dust storms, and restore degraded landscapes.

Drawing on satellite research, this episode explores how planted forests develop leafy canopies faster than natural ones and how successful environmental restoration depends on understanding complex ecosystem relationships beyond rapid tree growth. The discussion highlights the roles of biodiversity, water, and resilience, demonstrating that restoring healthy landscapes involves more than just carbon storage.
