Couple of interesting facts from the video. Bartlett talks about
the rule of 70 for doubling of exponential growth (any growth over
zero). That is, take the yearly growth rate of a city, say San
Antonio at approximately 2.8 percent and divide that in to 70 and
you get the doubling rate. That is, in 25 years, the San Antonio
area will double its population to around 4 million people.
A useful way to look at this type of population growth is to
consider a bucket of bacteria that doubles in whatever time span. Up
until the bucket is half full they can look around and say there's no
problem; we have plenty of room. Then all of a sudden the bucket
goes from half to completely full in one generation. It can happen
before you know it.
I believe that we have way too many people on the planet and
anything we can do to eliminate some of the dummies, I'm all
for. That is why I'm opposed to mandatory seat belt laws, child car
seats, texting bans, and helmet laws. If you aren't smart enough to
do these things out of common sense, you probably shouldn't be reproducing.
The trouble with some of that logic, like texting bans, is
that the perpetrator can easily survive the accident while the
innocent bystander who gets crashed into may die. There's no
protective logic in that one.
