When I emailed ecologist Tara Stewart Merrill and asked if she'd help me consider the ecological impact of Thanos wiping out half all of creatures on Earth (and everywhere else), she said that she had just gone on a long rant about that very thing! A scientist who also rants about Marvel movies?? Perfectly balanced, as all things should be (and as the Earth's ecosystems are definitely not, thanks to Thanos).
