Trained Rats for Mine Detection
rikomatic writes "The dangerous profession of anti-personnel mine detection is getting a surprising new tool: giant Gambian rats (NY Times reg). Some resourceful Belgians have figured out how to train these 30-inch rodents to hunt out landmines. They are cheaper and work harder than dogs and are more reliable than metal detectors. Plus, if one of them blows up, who's going to cry?"
You'll see that since they only weigh three pounds they don't trigger the mines.
If you can read this sig - the bitch fell off.
I know you're kidding but it's actually smart from the rat's perspective. They get bananas from it, and no explosion.
Rats are:
*Effective
*Cheap
*Relentless
*Not attractive
*Not heavy enough to detonate mines
Therefore, the ultimate mine-detecting device.
from the article:
Rats are abundant, cheap and easily transported. At three pounds, they are too light to detonate mines accidentally. They can sift the bouquet of land-mine aromas far better than any machine. Unlike even the best mine-detecting dog or human, they are relentlessly single-minded.
"Throw a stick for a dog to fetch, and after 10 times the dog will say, `Get it yourself, buddy,' " Mr. Weetjens said. "Rats will keep working as long as they want food."

In order to survive on this world we must eat living creatures - be they plant or animal. For a balanced diet we must have animal flesh; plant food just doesn't hack it alone. To get animal flesh we must kill the animal.
Actually, this isn't true. It's perfectly possible to have a balanced diet with all the human nutritional requirement simply by eating plants. The problem is that it's not easy: you have to know which foods have what nutrients, and be sure to eat enough of them. Protein is a big problem too; there are non-animal foods with a lot of protein (like nuts), but just eating salads isn't going to be enough. That's why there's so many college kids that have nutritional problems. They decide to become vegetarians because it's "cool" or whatever, but they don't actually do their homework and learn how to do it properly, so they end up with insufficient protein, low iron, etc. Eating meat makes it much easier to have a balanced diet.
For the record, I'm a happy carnivore.
Now, if you were talking about cats, you'd be correct: cats require certain amino acids that can only be found in meat. Dogs and humans are omnivorous, and can survive without meat if necessary, but not cats.
