would ecology suffer if roaches and mosquitoes were to disappear from this planet? how about virus?

Hate to say it, guys, but we are one of the top ranking worthless entities on this Earth. We think we are responsible for everything, animals and otherwise here because we pompously assume that we are the superior species. As George Carlin puts, 'We are nothing but fleas on the Earth-it can just shake us off.' (Well that's not verbatim) Anyone who hasn't read 'I am Ishmael' should give it a shot. Evolution has not stopped with us as the ultimate organism-and we should not assume that we are as such.

Genetic engineering has made us closer to a god on earth and we can now create new life forms never imagined before.We may be worthless but we sure have the capability to change the earth in the most unpredictable ways in all recorded history.Some people even compared man to a great cancer on the earth. Gordo

on the other hand, we're the only creatures capable of developing a system to thwart a comet or asteroid from hitting earth and killing 90% of lifeforms.

er... not yet anyhow. We're still working on the detection of comets and asteroids.

Not true, gumby, dammit. The first immigrants, the Irish and Scots, could pretty much fit into the US, being from basically English culture. They all spoke English.

The Polish came about 60 years after, around 1900. Throughout the late 1870's, Prussia, Germany and Russia carved up Poland, causing extreme poverty and political strife. As a result, a full 1/5 of Poland's population emigrated - most families could only afford to send 1 son overseas to earn a living.

When they arrived, they were not accepted by the Irish, English and Scots. The incoming populations spoke Austrian, Russian or Polish, but most had never seen English. Immigrants just stared at officials. Because of the language barrier, the first immigrants were labeled 'stupid'. The label has stayed to this day.

Thats interesting . It might be true if we say there are WMD on it and promise that we can make billions of dollars doing it. Otherwise it can't happen.

Interesting, since we are the only ones doing any ranking.

We think we are responsible for everything,

You can't stop being human by hating humans.

Evolution has

Evolution has to do with genes, and genes are chemicals. Now that we, alone among the species on earth, understand this fact, it's pretty likely we are going to be the cause of most evolution in the next few centuries. Of course whether that's likely to turn out well is another matter, but I suggest you wake up and smell the coffee, which is ready to pour.

Whether it's likely to turn out well or not is the scary part! And I guess I can't hate humans, since I am among that species But I feel it's a tad arrogant to assume we we will 'control' evolution- granted, we are doing very well in the department of exinction, but I have faith that the Earth will control this species that has overrun its bounderies. The viruses and resistant bacteria are starting to lay down some checks and balances! (By the way, I'm not really human...but I have mastered the keyboard even though I have big paws!!)) HA-HA!

but you're forgetting - *WE* have Bruce Willis & Ben Affleck!!

Oops... forgot about them. I'd better just put them on the list of 'who to call first' when we find the 'big one' headed our way...

True.

Control? Good luck.
