The risk that Venus is or was once host to some form of life, and humans deliberately contaminating Venus with life would obscure any evidence of it. That is a very serious worse-case scenario because non-earth life would be truly invaluable to biology.
It seems like a remote risk to me, but not something to shrug off. Particularly since the usefulness of introducing life to Venus is itself quite remote.

- ceejayoz 7y ago> Life in temperatures that melts lead? Why not? It'd have to have different chemistry, sure, but even on Earth life exists in some pretty extreme temperature and environment ranges.
- tfha 7y agoLife really starts to struggle above 100 C. I think the most heat tolerant organisms we know of top out around 130 C. Life that could operate at 500 C is probably not water based at all, which would be very novel and certainly interesting to science.
- darkpuma 7y agoEither. It does seem unlikely, but the truth is we just don't know.
- dougmwne 7y agoFor all we know the Soviet Vega missions could have introduced airborne microbial life into the high atmosphere. We may have already seeded Venus.
