I drive on tracks, not the bush, and I leave the areas I go to better than I left them meaning I take away other people's rubbish if required. I take my own fire wood and don't put plastics in the fire. I don't do waste water (I have a grey water tank), and if I have to road build I make it right before leaving. Other stuff as well.
But you said it well, the off roading I do is of no consequence when compared with what most humans do...flicking cigarette butts and rubbish all over the place, overusing fossile fuels, general wastefulness, consumerism, new phones every year, use of chemicals...the list is long.
Ah, that's all extremely awesome! I wasn't sure how much you'd think about it... but it sounds like you think about it a lot. I appreciate that... even though humans are messing up so much of the planet, if we can try to keep our exposure to pristine areas as minimal as possible, I'd like to think most of us should try.
We didn't inherit this world, we're looking after it for our ancestors.
Most people here do the right thing when they're out there although there's always a few bad eggs I guess, people who gather fire wood which destroys the places little creatures live, or who don't air down tyres which tears tracks up and, of course, those who litter.
