Did you know aliens live among us? IPBES just launched its landmark new Report on Invasive Alien Species and their Control – the largest study ever of its kind. Join Brit as she speaks with one of the co-chairs of that Assessment, Professor Helen Roy, about her enthusiasm for addressing these risks and her optimism about our chances to reduce biological invasions and their very damaging impacts. Brit also interviews Dr. Maria Loreto Castillo about how the simple beaver has become the focus of some very complex opinions in different parts of the world.   You can listen to the playlist Helen mentioned here: open.spotify.com/playlist/2YvpQrvhQxvUm9AirBlcvW?si=MBXLr8Q8QIOdaOcwTmbFbA&nd=1   To find out more about IPBES, head to www.ipbes.net or follow us on social media @IPBES.
