### Name a species...

...that humans do not possess the ability to kill off.  Thus far the only challenge we have is "insects", but this is not a species.  Rather, it is an entire class.

Hi Ricky;

Any species that is smaller than us is probably safe.

It would be rather easy to kill off all dogs.

If you accept that humans could burn all vegetation, then mice and bees are out.  Indeed, burning all vegetation would (I believe) kill all warm blooded animals, and then E. coli would go as well.

Rabbits! My God, are they hard to kill! Australia has an infestation of 'em since Settlers came! We've tried everything but they just keep coming back! We tried the virus' but their descendants became immune! Dynamite is also proving no good. So we got foxes over here, but now they're just as bad! They keep stealing everyone's chickens & sheep!

Pay attention to Tigeree's post. It is a good example of the folly of attempting a mass extinction.

E Coli lives in our own intestines. Killerbees don't need vegetation to survive. Rat populations exceed human ones in US cities. You are refusing to come to a conclusion, that there are many forms of life physically much more robust than man. They were here hundreds of millions of years before we showed up.

Ohh, OK. I understand the question now.

I'd say that there are certainly some species that could survive being hunted with non-drastic measures, ie. methods that wouldn't also cause extinction of humans.
Tigeree's rabbits could be an example, but I'm sure there are other species that are even better at surviving. Mosquitos or something.

If we don't care what happens to us, we get to use some 'more effective strategies'.
I'm guessing we have enough destructive power to destroy the Earth, but not disintegrate it.
So we'll be able to turn Earth into a bunch of rocky bits for a while, but it'll eventually reform into Earth 2.0.

So that's eliminated all species that need an atmosphere or that can't survive severe heat or radiation. I'd imagine there'd still be some survivors after that though.

How feasible would it be to attach a giant rocket to Earth and launch ourselves into the Sun?

This is something I've been thinking about.  It would be much easier to try to move the moon into Earth's gravity well, and then Earth's gravity would accelerate it.  Would that momentum be enough to drastically change Earth's orbit?  The moon is roughly 1/5th of Earth's size, which is obviously no small potatoes.

But alas, I don't think moving the moon is feasible right now, and for some great time to come.

E Coli lives in our own intestines.

I never said we would be around.

Killerbees don't need vegetation to survive.

You're going to have to explain that one.

Rat populations exceed human ones in US cities.

And?

You are refusing to come to a conclusion, that there are many forms of life physically much more robust than man.

That isn't the game we're playing in this thread.

They were here hundreds of millions of years before we showed up.

Irrelevant.

They would survive without us. Man's demise does not signal the end of creation. We are not the beginning of it or the end. Killerbees nest in dirt they don't require vegetation. They live happily right inside out concrete cities.

Just an answer to your point that we could wipe them out. The fact is we can't. They can live on garbage, in rubble. They can feed on almost anything including humans. They are resistant to disease and pesticides. You state that control is marked by the ability to wipe out any other species, we are not capable of that.

I mentioned humans being able to wipe out any other species as a characteristic that no other species on this planet shares.  I realized this was indeed only tangential to dominance, and made a post to this effect.  I then created this thread because it felt like a fun game.  Leave the dominance in the dominance thread, we'll talk about killing things here.

I've replied to the rest of your post that had to do with killing things here, and I replied to the dominance piece in the dominance thread.

E Coli lives in our own intestines.

I never said we would be around.

They would survive without us.

Granted, e coli also live in the intestines of other warm-blooded animals, but they wouldn't be around either.

Killerbees nest in dirt they don't require vegetation.

And pray tell, what exactly do they use for substance?

Oh, here is another species we can't wipe out, sharks.

Endangered Shark Species

Oh, and "shark" is not a species.

I'm thinking that probably wouldn't work. The Earth and moon are currently orbiting the Sun as a system, and if you caused them to crash into each other they'd still be doing that.

Bacteria live all over the surface of the earth and in the stratosphere. They can survive without air, at extreme temperatures, in sulfuric acid or radioactive wastes.

Ricky wrote:

Correct! That page only states by mans reckoning that some species of shark are endangered. Lets not forget the Coelacanth.

You still have not suggested any other means other than some Buck Roger's solution to eliminating rabbits, bacteria, rats, roaches, killerbees...

### Re: Name a species...

New idea to deal with these ocean-dwellers: how possible would it be to boil the seas?

Thank you!  Someone is trying to play along...

I did some quick calculations, starting with these assumptions:

Average temperature of the ocean: 4C
Volume of the ocean: 1,260,000,000,000,000,000,000 liters
Specific heat of ocean water: 4.186 J/gram C (note this is the specific heat of pure water)
Average payload of a nuclear weapon: 1000 TJ
Percent efficiency (the amount of heat that actually gets in the water): 20%

It seems like this is a reasonable upper bound, assuming the nukes are evenly distributed across the ocean.  The number I arrive at is 2.530.000.000.000.000 nukes.  Please check my work.

### Re: Name a species...

Yeah, that's exactly what I get. Even raising the temperature by 1 degree would require

nukes, which is ridiculous, seeing as we only have 23000 nukes in the world.

The nuclear winter would be more catastrophic however, it could plunge the whole world into a possible ice age. Humans would likely not survive. But an ice age has occurred before, and those lucky enough to be adapted to it will survive. In particular, I've heard that co.ckroaches are specially adapted to survive nuclear fallout.

I don't know which species would survive, but an ice age has occurred before, and obviously certain species did survive.

I think suicidal bombardment is the 'best' way humans could try to eradicate another species. They would succeed with most species, but not with all.
