In the second episode of Extrapolations, we follow Rebecca, played by Sienna Miller, and her son Ezra. The story is set around 11 years after the first episode, and shortly after many of Earth's megafauna have gone extinct, after ocean acidification has played out and the krill are all but gone, and the marine ecosystems on top have collapsed.
Rebecca is some sort of conservationist, who communicates with the last individuals of a species. Her son is stricken by a heart condition bought about in the womb by the soot and wildfires which you might recall from Episode 01. Rebecca is tasked with conversing with the last ever female whale as it searches for an elusive mate. Again we see themes of corporate malice, inaction over climate change, and the expectation that the next generation will clean up today's problems.
The backdrop includes lots of subtle sci-fi elements, so again if you're interested in near-future sci-fi dystopia, and interested in nature, this might be one for you. However unlike. Say, Black Mirror, this series does feel a little less hyperbolic, more grounded in reality. It seems like we're not looking at a parallel universe; we're looking at our own future. Or at least a single perspective and spyglass on that future. The conversation hints at a message; if we don't change, our trajectory wont change.
