Spitzer’s Hypocrisy

Tuesday, March 11th, 2008

The lady doth protest too much.
- Queen Gertrude, Hamlet Act 3, scene 2, 222–230

Eliot Spitzer was an outspoken prosecutor of prostitution, and now we know this hypocrite dirtbag is guilty of indulging in what he believes should be a crime.

As I have argued before that prostitution should be legal. Sex is legal, making money is legal, sex for money should be legal. It is the illegality of prostitution that exploits and victimizes women, not the act itself. Legalized prostitutions would be safe, federally regulated, and taxed like mad.

Spitzer’s crime is two-fold. First he criminalizes women who sell sexual services, and then he exploits them by feeding into the market demand for those services.

The Sixth Mass Extinction

The most famous mass extinction is the Cretaceous-Tertiary, which killed the dinosaurs 65.5 million years ago. It was most likely caused by a meteorite that left a crater 150 miles in diameter off the Gulf of Mexico and a layer of iridium-rich dust all over the planet.

However the Permian-Triassic extinction was the most dramatic. Scientists still debate what cataclysm could have caused 90 percent of all life on Earth to suddenly vanish 250 million years ago. Meteors, mass volcanic eruptions, global warming, and even a sudden burst of space radiation have been proposed to explain it.

A solid consensus of biologists have established that the Earth is now experiencing a Sixth Mass Extinction event, the Holocene Extinction. This Mass Extinction event began 100,000 years ago, it’s like nothing the planet has ever seen before, and it’s all our doing.

It is theorized that Native Americans wiped out 80% of the North American animals within 1,000 years of their arrival, driving the giant ground sloths, camelids, giant armadillos to extinction. The disappearance of Woolly Mammoths, Irish Elk, Cave Lions, Cave Bears, Cave Hyenas, and even Neanderthals occurred after humans arrived in Europe. The ecosystems of Australia, the Caribbean, and Madagascar suffered collapses in biodiversity shortly after humans appeared in their environments 40,000, 8000, and 2000 years ago respectively.

Today the Earth is losing 30,000 species per year. That averages out to three species going extinct every hour, and with them go their genetic uniqueness, beauty, and contributions to our ecosystem. Each species lost detracts irretrievably from our own quality of life. Extinction is forever.

Physicist Adam Lipowski, through computer modeling, has found that, throughout evolutionary history, mutations regularly produce “superpredators,” a life form so stressing on the ecosystem that it extinguishes entire food chains, destroying even itself in the process.

Are humans a superpredator? Obviously we once were, through no fault of our own, but through the success of our genetics. We didn’t know any better; today, however, we have science, which is a blaring klaxon, alerting us to what we are doing to our planet’s biodiversity and ourselves. Human beings, unlike sharks and bacteria, have a cerebral cortex. This component of our brains gives us the ability to override our baser impulses and become masters our fate.

The World Conservation Union currently lists 40 percent of all species on Earth as endangered. This is a terrifying statistic, but it also means that there is still hope. There were a scant 750 bison left in America in 1890. Today we have brought their numbers up to 350,000, far less than the 60-100 million estimated to have roamed the United States in the mid-1800s, but proof that we still have some time left to change our course.

The world’s frogs, bees, polar bears, whales, and fish stocks are our planet’s “canaries in the coal mine,” and what drives them to extinction may mean our own demise. Unlike miners who can escape to the outside, we have no other planet to run to. Over 99% of species that ever lived are now extinct. Let’s not join that statistic.

Science Etcetera Marsday, 20080311

  • National Science Engineering Week started on last Venusday, but I forgot to blog it. Check out the site for resources, events, and other fun stuff.
  • Did not know that! When the astronauts came back from the Moon, they had to file a customs report declaring the Moon rocks they brought back.
  • Hooray!!! A scientists who worked at the Fermi National Accelerator Laboratory for 22 years has taken former GOP House Speaker Dennis Hastert’s seat in Illinois.
  • In more good news for Democrats: People do not grow more conservative, but more liberal as they grow older on average. Bite me Winston Churchill–sorry, he never actually said that (more bad news for Republicans! Yay!).
  • The Oklahoma House of Representatives has passed a bill that may prevent a student from failing biology class for answering, “The Flying Spaghetti Monster did it.”
  • But religion isn’t all bad, however irrational, the Vatican now lists polution as a sin… and genetic manipulation too, so it’s 50/50 good news. Even better when you add the Southern Baptist community to the environmental fight.
  • I wonder if this would count as “genetic manipulation,” an Injection of human umbilical cord blood helps the aging brain. Yewwww.
  • Despite two civil wars and the lost of 90% of their habitat, a camera trap has proven the survival of pygmy hippos in Liberia
  • WR 104 is two stars orbiting one another like a pinwheel, and one day it will probably emit a blast of deadly gamma rays right at us, and we won’t see it coming because it will travel at the speed of light. So Carpe Diem! pygmy hippo!
  • The Science Creative Quarterly has a sobering article today about the eight-year imprisonment of foreign medics in Libya who were accused of infecting children with HIV, and how Scientists rallied together to gather the evidence to help them.
  • Owning a cat reduces your chances of a heart attack by 30%, obviously they didn’t factor my mewling, poop-machines into the equation.
  • Today’s Moment of Science involves a bit of self-discovery, estimating how much carbon dioxide you’re emitting each year with Berkeley’s Cool Climate Calculator. I emit 56% of what the average US household does thanks to being a flexitarian and not needing much in material wealth, but I’m 300% of the global average for living in a house bigger than I need and driving too much in my 16 MPG pickup truck.
