The last feature of the year is about invasive species, one of the key causes of biodiversity loss, which has been the focus of the COP15 summit at Montreal that ends this week.
We, Homo sapiens, are of course the most invasive species of all, and most of the others have invaded in our footsteps. They often travel as stowaways, such as rodents on ships, but in some cases have also been spread intentionally by people wanting to "enrich" their local flora or fauna.
For the feature I have rounded up some examples of such accidental or stupid invasions, along with new ways developed to fight back against harmful invasions.
