Re: Are we really Overpopulated?
OGF, what I picked up from this and from you (so correct me if I am wrong) is that dire dystopian pictures of overpopulation leading to mass famines and pandemics are unlikely. More, the limiting factors that we worry about can be overcome with technology.
However, this podcaster is talking about nothing more than the quality of life of people in developed countries, and that popular campaigns to curb behavior like having more than two children, meat eating, or driving one's car unimpeded aren't causal to a future that might not be that bad. In reality, his primary concern about whether or not he can have a steak, whether or not there will be revolutions in the streets, and mostly whether or not his DNA is passed on. I too think that the dire pictures for most of us have been exaggerated, but this guy is missing the point.
This change in model outcomes does not address issues of the impoverished, people living in high population densities, ecosystems, geographical places that matter, and wildlife that are already occurring. I was reading an article just last night about an Indian village that is on the verge of collapse and famine due to years of unimpeded offshore trawling for fish to be sent to China. The Chinese aren't there because India has a very special delicacy. It's because they have a massive number of mouths to feed - and that fish is free.
I challenge anyone here to convince me that their roads aren't as congested, their shorelines are less filled with plastic, or that we have more old growth forests and rainforests than we once had.
If it isn't the increase in population that is causing such headaches (and holy cow, those problems are pathetic by comparison), then what else can the negative effects we are seeing? Do any of us really think that the problems we have now will improve? If it's not population, then could it be... consumerism? Yikes, now there is a can of worms. Do we really want to stop lifting people out of poverty to save polar bears or do we want to encourage them to have smaller families by making birth control easier to get?
Or do we just say the heck with it and not worry until if/then there is a crisis? I don't know about most people, but I was raised and still lean towards being conservative and preparing for that rainy day.
With our lives of privilege, we have the responsibility of stewardship of everyone and everything that is without power. We can't turn a blind eye to it. Something is causing the mess - and yes, it is a growing mess.
I was once a (boring) statistician, and I know that it is unwise to lean to hard on any study especially when it comes to causality. It is ill-advised to dust off our hands either way when it comes to human population.
