Edit: My experience is in western Canada. I forgot that hackernews is a global site. Some countries do grow pine specifically for paper.

Then industrial processes shouldn't use groundwater. It doesn't sound like a good idea to site them where there isn't abundant surface water.
But yes, if they use surface water, it considerably reduces the impact vs groundwater.

That being said, I wish this guy luck. Having different tech available for use in areas where it would be a better way to do things is not a bad idea.

Aside: supposedly global pulp production is 34 percent recycling, 45 percent from sawmill waste, and 21 percent 'logs and chips.'[0] The wikipedia article later states, from another source, that 16 percent of production comes from tree farms. The gist of your general point stands, as I understand it: we're not going out and cutting old growth or even secondary growth forests for paper (though we make use of reject trees when we target them for other reasons).

(not to say a limestone quarry is a better solution...)
I have also spent time with Lynx at a close proximity, both times they purred and acted like a house cat. Before hissing and slowly walking away.
I'd also like to point out how great it is that we have such varied commenters here on HN. I checked in tonight to see what's new with the NSA/Apple/Snapchat/usual tech stories of the day, and instead I got this gem about the timber industry and wolves.
I'm sorry if I come across as stupid. I don't see the connection between these two assertions.
If it's intended to be a "simulate (a substantial part of) everything" game, the above stories suggest game elements such as different depths of snow, non-hostile wild animal interactions, animal pathing behavior in snow, tracks, and animal habits/routines.
Dwarf Fortress has for a long time used short stories to describe interesting interactions that the developers like, and then tried to add features to the game until similar events can just happen naturally.
(Which still isn't 100% ideal, because monocultured pine isn't friendly to the local species and they're generally devoid of animal life, but way better than clearcutting wild forest.)

>Official figures show more than half of Indonesia's rainforest, the third-largest swath in the world, has been felled in a few years and permission has been granted to convert up to 70% of what remains into palm or acacia plantations.
>Nine villages have been in conflict with the giant paper company April, which has permission to convert, with others, 450,000 hectares of deep peat forests on the Kampar Peninsula in central Sumatra. Because the area contains as much as 1.5bn tonnes of carbon, it has global importance in the fight against climate change.
> To make a ton of regular paper requires 100 tons of water, TBM says, while its Limex paper is made without water.
Here in Canada we have the Great Lakes which account for 21% of the worlds fresh water. And they're rapidly becoming polluted.
Humanity always finds a way to squander whatever resource you think we have "excessive amounts" of.
200 kilograms of polyolefin, a class of compounds produced by polymerization of alkenes, which are derived from petrochemicals or ethanol, both of which come from water-intensive sources.
Also, is this stuff biodegradable at all? It's basically stone dust infused with an extremely stable plastic. This stuff would last a thousand years in a landfill...
And as others have pointed out most of the raw material going into the local paper mill was saw dust from the local sawmills.
Hardwood pulp is just barely worth more than the stumpage fees that the loggers must pay to the landowners. Depending on the market, softwood pulp can be even less profitable.
Plantation trees are used to make paper in New Zealand and Australia. That is my personal observation, but it is enough to disprove the claim that paper is only made from dead or rotting trees.
Same for Brazil and Uruguay - they go for certain kinds of eucalyptus trees. How do I know, not having visited either country?
My wife is a chemical process engineer, and Finland has a large pulp and paper industry. The technology universities feed process and design engineers there. (To a point where some universities' chemistry departments have been neatly coupled with local pulping industry.)
Eucalyptus family has some surprisingly fast-growing varieties. Also, according to the industry, their fibre competes in quality and properties with Scandinavian birchwood. This kind of fibre is particularly wanted for high-quality printing paper.
It takes 40-50 years for a birch to grow from seedling to a pulpable "product". With plantation eucalyptus, this time frame is compressed to 15-20 years. You can crunch the numbers.
The irony in this is that in in order to make space for eucalyptus plantations, the industry had to cut something down first. And due to the time frames involved, they need to constantly make space for new plantations so they can provide a reliable future supply.
The thing they cut down? Rain forest. (Among other things. But certainly enough of it to warrant concern.)
Final note: you can't grow eucalyptus in Scandinavia. According to Brazilian process engineers, eucalyptus can withstand one or two sub-zero temperature nights a year. Call it two max. Not two hundred.
