A terraforming animal meets a terraforming animal, to find out while its ancestors extincted the terraforming aninmal previously.

Beavers will build dams and lodges into the infrastructure, will undermine the whole river bank and start damning up canals. Its easy to cheer this on from a nature in the abstract loving position.

But in the real world, this results in the need for constant repairs and downgarded performance.

If the headline was "German bombers drop smart anti-infrastructure water-bombletts into thames \ blitz getting more expensive by the day \ pratchett fans cheer for modern Ankh Morpork" it would describe a similar situation, without the disney googles and nobody would celebrate it.

Here around Bratislava the beavers are doing their stuff last ~10 years after a long absence. A few people are scandalised by the felled trees. Otherwise no issues. They are not causing problems for massive concrete dams we have on the Danube. For smaller rivers, the changes seem to be positive.

In my country there were some locations where they have added bevers population on purpose. This was in the rural areas. And there was a lot of floods and damages on crops, orchards, etc.

Our ancestors extirpated the beaver out of a mania, which developed among the former, for wearing the skins of the latter upon their heads.

We often assume our ancestors to be idiots. Would they have done it if beavers were found to be generally beneficial? (I mean probably, because capitalists are going to sell their last breath of air if the price is right; still worth asking)
