Back in the late 80’s there was a sci-fi tale of comet wranglers slinging comets into Mars to create craters, water, and a spot for a biodome.
The team on Mars was testing out biotech items, a fast growing grass carpet and a bioengineered dog that didn’t need fancy airtanks and such.
In setting up the dome they found the dog loved the lower pressure atmosphere.
They released the carpet and later found it was too aggressive and had to beat it back from the ramp before retreating.
The story ended with a letter to the board that read in part “I’m afraid your carpet ate your dog.”
I like that concept...
