Re: the overpopulation discussion
Would just like to point out that Harry Harrison wrote
Make Room! Make Room! (the dystopic sci-fi novel that
Soylent Green was adapted from) in 1966, in which future America of 1999 is a hellish overcrowded nightmare of 344 million citizens, out of a world population of seven billion.
Estimated current US population is just under 325 million, out of a world population of 7.4 billion. And we're still far, far away from being a dystopia so crowded that we're eating algae biscuits and dead bodies. So yeah, overpopulation is a problem, but overpopulation alarmism is nothing new.
And US population growth has been remarkably stable over the last fifty years, with growth rates hovering just under 1% annually for the last 15 years. Immigration has ticked up, but fertility rates have declined and mortality rates have increased (no surprise as the demographic bulge of the Baby Boom hits their senior years).
If you were to extrapolate current trends out, then by 2050, over 2/3 of all population growth would be due to immigration, and yet the overall population growth would be at the lowest in over a century, and population density would only have increased about 25% over current levels.
Plus we have a
lot of uninhabited land in the United States, with 10 states having a population density lower than that of Saudi Arabia.
Now the UK might have legitimate worries, but that's what you get with living on an island.
