Biodiversity is essential for healthy ecosystems from "summary" of Bringing Nature Home by Douglas W. Tallamy
Biodiversity is the key to the functioning of healthy ecosystems. It is the variety of life forms – the different species of plants, animals, fungi, and microorganisms – that interact in complex ways to support life on Earth. Each species plays a specific role in the ecosystem, contributing to processes like pollination, nutrient cycling, and pest control. When biodiversity is high, ecosystems are more resilient and able to withstand disturbances like extreme weather events or invasive species. Without biodiversity, ecosystems become less stable and more vulnerable to collapse. When a species disappears from an ecosystem, it can have far-reaching consequences, disrupting the delicate balance of interactions that support life. For example, the loss of pollinators like bees and butterflies can lead to a decline in plant reproduction, affecting the entire food chain. Similarly, the extinction of predators can result in an overpopulation of prey species...
