Ancient forest is so rare as to be almost non-existent in Britain. This is because we gradually cut it all down over a long period of time [1], presumably on the iterated basis that there was a lot of it and that cutting down a few square miles was really not a big deal.
Some of it has been replaced in the last hundred years, but the replacement is of a very low quality, relatively speaking: mostly just fast growing conifers.

This feels like a critique of the parent, but if so it ignores the key point: BC's forests cover 230k square miles [0]. The entire island of Great Britain is only 80k square miles, 15% of which (12k square miles) was estimated to be forest in 1086 [1].
To put this in perspective: If British Columbia deforested itself at the rate Britain did (an average of 9 square miles of forest lost per year), it would take 25 thousand years to finish the job.
Yes, BC needs to log responsibly, like everyone else. But "responsibly" for BC has a very different definition than it does for Britain, and imposing British sensibilities on Canadian logging isn't useful.
Unfortunately British Colombia isn't deforesting at a rate of 9 square miles per year, it's been deforesting at an average rate of ~1579 square miles/year for the past 21 years. [0] At that rate it'd take about 145 years to finish the job.
Depite the seemingly limitless bounty of British Colombia's forests modern technology will let us wipe them out in a fraction of the time it took pre-modern Europeans to do it to their own continent.
There are definitely more pressing concerns around the world with regards to deforestation than BC - at least BC are making some efforts to preserve their forests and replant, unlike many equatorial countries with arguably more precious rainforest ecosystems. But a net loss is still a net loss, and tree farms are not a one-for-one replacement for old-growth forest.
As an aside: the 15% forest cover Britain of 1086 wasn't its pre-human state - it was aleady heavily deforested by humans. Prehistoric and ancient humans were very effective at deforestation, since the most popular method of early agriculture in Europe involved burning swathes of land, farming the nutritious soil left in the fire's wake, and then moving and burning more forest when the soil became useless.
By the beginning of recorded history Europe had already achieved most of the deforestation it ever would.
One of the most worrying attitudes I see held by humans is “don’t worry we have near limitless sources of X” — whether X be water, forests, land, energy, atmosphere, etc.
I really liked Isaac Asimov’s “The Final Question” for exploring the attitude that humanity has near limitless resources. Unfortunately for us, we may not have faster than light travel to exploit the resources of our universe.
Also resource total isn't resource density. we're basically at carrying capacity in tens of different ways.
Whatever we do on jupiter is irrelevant. Using more than about 100kW/person on earth will cook it even if it comes from thermodynamically limited 85% efficient solar panels due to albedo increase. Making your exponentially increasing pile of garbage in the asteroid belt and importing it doesn't work either because just getting it down will produce heat and NOx.
