Living in a ‘mass extinction’
(particle.scitech.org.au)
It's not only individual species, but entire ecosystems that are collapsing.
I think we need to seriously start thinking about transplanting for example coral reefs into locations with a colder climate, although it will probably not help much in that specific case as the acidification of the ocean that makes it hard for the corals to form their exoskeleton is global issue.
