Stargates an ecological nightmare?

[RedWolf]

In the real world human travel can give a great impact to local ecology by introduction of flora, fauna, viruses and bacteria.

Looking at the Ancients' mistakes, Stargate travel is an ecological nightmare waiting to happen.

1. The plague which wiped out life in the MW galaxy. (But in the Pegasus it seems they wisen up a bit adding biofilters to the stargates.)

2. The spread of human populations in the Pegasus galaxy lead to the evolution of the Wraith.

3. The Goauld would not have become a threat if they did not leave their world.

This was dealt with early on, in series two 'one false step'. The explaination was that as Humans are everywhere any way most of the microorganisms are similar to our own.

How do you know they have biofilters? I've never heard anything of that. I know they have atmospheric filters but thats it.

I think that was a little bit too convenient on the part of the writers. Anyway they kinda contradicted themselves in season 6 when Nirti had Jonas in that Ancient gene manipulator thing. She said how living on another planet for so long his people have changed some compared to Earth humans. However the shows are called Stargate SG-1/Atlantis not Stargate Epidemic.

everyone uses the stargate all the time, the microorganism would be spreal all over the place. to the point their not dangerous as our bodies become accustomed to them, in te begining this was probably an issue.

I think your right I got mixed up in remember.

Season 4 episode Tabula Rasa Atlantis' system would only screen known dangerous viruses.

The virus that hit Earth born humans did not have a immunity to a virus.

[Lord batchi ball]

Well the only way place I can percieve a problem is in the PG. Since we can get their diseases they should be able to get ours.

But I doubt they could get the plauge unless we have a stange habit of carrying small rodents with us through the gate.

[Garth Claw]

Given that most planets the goa'uld moved Humans to have naquadah you would have though that there biochemistry would have altered to include the element, as would all life on the planet. Given Earth doesn't have any you would have though those micro-organisms affecting us would not have been able to interact complete with off-world bugs.

If a protein requires amino acid with naquadah in them Earth bio chemistry wouldn't support them.

Also do agree with you SP90, it was a quick fix to a long term story problem, the plot hole is avoided ;-)

Because like Earth and a few other planets (Euronda, Bedrosia/Optrica, Rand Protactorate/Caledonia and Earth) had their gates buried and weren't affected the same way as 90% of the rest of the galaxies' planets were.

Vala,

Kind of saying things after the fact aren't you? If we're doing that then we should go back several hundred years and sink the ships of Magellan and Columbus.

No one knows how the future will play out.

That could work for planets where Stargate travel was a regular routine. However, Earth has been isolated from the gate network for thousands of years, and viruses and bacteria mutate fast.

The Ancients had a Time Jumper. They could go back and undo the Wraith if they so chose.

[Opener]

But they didn't because even the Ancients couldn't master time travel. Sure, they can go back and forth, but even they couldn't tell what all the effects would be. That's why they didn't let Weir go back to her own time in Before I Sleep, they didn't want to damage to timeline.

Besides, taking out the Wraith could create a time paradox, the results of which could start a chain reaction that would unravel the very fabric of the space time continuum, and destroy the entire universe! Granted, that's a worse case scenario. The destruction might in fact be very localized, limited to their own galaxy.
