I'm sure they believed they were defending freedom.
I'm sure they a) didn't care and b) didn't think about it. The two go hand in hand.
Because freedom's just another word for nothing left to abuse.
You think freedom sucks for the environment? Try its absence for something even worse. Free people care about the environment far more than slaves.Classic example is the difference between the West and Communism during the Cold War. The Aral Sea is just about gone because way back when, some central planning group decided to turn a bunch of desert into farmland without considering the consequences. Bad stuff happens in the developed world too, but you can't be stopped from caring about it. And as a result, those sort of decisions have a lot more push back and don't go as far.
The US-equivalent is the Salton Sea which was made by an epic mistake, the accidental redirecting of the entire Colorado River into Imperial Valley for a couple of years at the beginning of the 20th Century. Neither the US or Mexican governments (the flooding actually originated on the Mexican side of the border) contributed much to the effort of restoring the previous state. It took the regional railroad (which was greatly impaired by the flood waters to stop the flooding.
Freedom kept the Imperial Valley from just being the Salton Sea. Lack of freedom damned the Aral Sea.
It took one or two guys on 4wd offroad vehicles, after tearing down and shooting up the private property signs and fences, then doing donuts and running all over the site one day, to destroy all the work I'd done terracing and replanting the site, and turn much of it into gravel and gullies in the next rains.
If a couple of off-roaders can set you back to square one, then you are doing it wrong. Nature is not all-enduring, but it can take a beating (such as the forest fire, which was much worse). I also see this sort of flawed thinking in environmental science fiction all the time where there is some fragile terraforming ecosystem that requires constant human attention. Bonus cliche points, if their animal companion/mascot looks on as they toil away desperately trying to save the gimpy tree for the future of their new world.
My view is that this is not ecosystem restoration or the terraforming equivalent, but landscaping. Its private property and if you want to make it look pretty, that's fine with me. Off roaders in that situation were committing a variety of crimes in trespassing on the property and vandalizing it. Too bad you didn't catch them. But it would have taken more than that to derail a proper land restoration project. Sorry.
