Are humans part of nature or separate from it? How do we define native species, and should we always strive to eradicate invasive ones? Can urban green spaces play a role in addressing climate change and biodiversity loss? And what is the Anthropocene anyway? These are only some of the questions I discussed with Dr. Marcus Collier, an Associate Professor of Sustainability Science at Trinity College Dublin. His expertise in nature-based solutions gives us a new perspective on answering these complex questions and a fresh approach to environmental issues. In this episode, we talk about the fascinating world of novel ecosystems. We explore the complex relationship between humans and nature while challenging traditional notions of ecosystem restoration and conservation. I asked Marcus to clarify the concept of the Anthropocene and its implications for our understanding of the human impact on the environment. We also didn’t shy away from the controversies surrounding invasive species and ecological restoration practices. Marcus shares his insights on how our perception of time and history influences our approach to ecosystem management and highlights the challenges of defining a "natural" state in an ever-changing world. Then our conversation shifts to cultural landscapes and urban environments, highlighting the importance of nature-based solutions in cities. Marcus emphasises the benefits of urban greening initiatives, from improved air quality to enhanced mental health, while acknowledging potential drawbacks like gentrification. He advocates for a multifaceted approach to environmental challenges, emphasising the need for both technological and nature-based solutions for issues such as water quality and climate change.
