How do we deal with invasive species and repopulation in the natural world?

<p>Humans have been shaping the environment for decades, and so have other species. When humans do it, it often has some negative, unintended consequences. Laura, Ellie and Antonia discuss some invasive species that were intriduced to Australia and what was done to try and manage the effects along with the battle of grey versus red squirrels in Victorian England and the lasting effect that it has had. Conversely, where a species has been completely removed from an environment, the team also discusses how they can be carefully reintroduces and the consequences that beavers could have as environmental engineers. It sounds like we want beavers to use smart phones but We're not quite sure that's what we mean. Why not judge for yourself?</p>
