The main segment is a TED Talk by horticulturalist Rebecca McMackin, who advocates for ecological gardening practices that support biodiversity by using native plants, providing habitats for wildlife, and reducing the use of harmful chemicals. She shares her experience transforming a post-industrial site in New York City into a thriving park and urges listeners to embrace a less tidy, more natural approach to gardening to help combat the biodiversity crisis.
