No kidding: “Reproductive success” might mean not reproducing:
Just take a look at the mark that we are leaving upon the world. In many regions, major rivers are being reduced to a trickle by the time they reach the sea. Lakes are shrinking and water tables are falling at a precipitous rate. Tropical forests are being hacked down to satisfy our demand for hardwoods and palm oil. Ocean fisheries are collapsing as a result of overfishing. We are rapidly exhausting our limited inheritance of metal and minerals. Vital bio-habitats, including coral reefs and wetlands, are disappearing at a fearsome rate. Scientists warn that human activity is triggering the “sixth mass extinction” in the history of the world. Within the lifetimes of children being born today, humanity will likely preside over the virtual extinction in the wild of lions, tigers, elephants, and rhinos. And then there’s the question of what we humans are doing to alter the planet’s climate and the impact that will have on the future of all life, including human existence. That’s not my idea of reproductive success.
[There are times of difficulty ahead.]
