The included video interview with the journalist Emma Marris is interesting. She makes the reasonable points that 1) the environment is always changing, so determining a baseline for “pristine” is impossible, 2) humans are part of the environment and 3) many natural environments that we take for granted, such as Hawaiian forests, are populated heavily by “non-native” species that were introduced so long ago that no one now thinks to object to them. This is the environmentalist version of Saint-Exupéry’s observation that people who object to technology are typically objecting only to new technology.
Why is this mere partial sanity? Marris points out that the pythons are here to stay but doesn’t seem to consider whether allowing people to hunt them might be a good way to control the snake population. But perhaps I am being too critical.
