After reading through this article, I just feel that I really need more info. Could you suggest some resources ?

It is true that human do move things a lot, and I also agree with the facts that climat changes probably helped many invasive species to seetle and reproduce in their new environment. I can’t help but wonder what would the world be if climat changes would still occur without invasive species being carried over by human. Be consious of the fact that natural invasion are very rare and that many species need a specific environment to be able to carrie their fonction and life cycle. With increased climat change, there is always a possibility of migration of those species to follow their environment up until they hit a wall (say a desert, a montain, an ocean) were they will eventualy disapear. And for those who can’t really migrate, well its though luck for them. In our world, invasive species are filling those gaps (as well as taking other species place). That’s why i think the patagonia is right. This problem is overshadowed by a bigger issue, climat change.

I enjoyed your post, and I believe your question is hypothetical but I would like to respond with some thoughts; global warming is more like an umbrella issue, overarching a variety of other local to global-scale environmental changes. I dont believe that global warming can be directly compared to other global changes as it is interacting with these issues, not seperately. For example, the issue of transoceanic ships carrying around plants, animals, pathogens, bacteria, etc.: under normal climatic conditions only a fraction of these species would survive outside their natural environmental/ microclimate, however, the species being transported will be increasingly likely to survive and establish themselves in the oceans, lakes and streams where they are moved to due to global warming. I loved the way you say that we, humans, are the worst invasive species; we combat vectors like moisquitos carrying malaria but what are we doing to cambat human vectors carrying and spreading just about every living thing.
