Mega-cities are the most nature-friendly way of living, because they pack most humans over the smallest possible area. I'd love for everyone to live on their little farm with a nice orchard in the back, but that's just not feasible.
Also, is strikes me as extremely elitist that you complain about people going on man-made green paths or private beach hotels. Is my appreciation of a forest lower because the path has been gravelled by someone, or my appreciation of a sunset over disappearing horizon not as important, because there's a 5 star hotel behind my back? It's just extremely bigoted to say how someone can enjoy something.
Paved/defined paths rule (and keep us safe) and I wish more and more people would go for a hike instead of rotting away in front of a tv watching GoT ;)
Sunset: try Aigiali in Amorgos :)
1. I'm a vegetarian, potentially transitioning to veganism.
2. I don't own a car; I mostly take public transit.
3. I take recycling and composting very seriously.
4. I pay attention to my purchases (e.g. I don't buy nuts like pistachios and almonds due to California's drought).
I could go on, but you get the point.
I realize that I'm probably an outlier, but I would argue that many of us city-dwellers have a head start on "protecting the environment." As a sibling comment said, living in an urban area is more efficient by default, so I'm curious to know what lifestyle choices are made by non-city dwellers en masse that makes you think we are at a disadvantage? A public park might require tons of water to sustain, but so do golf courses, people's front lawns, and plenty of similar things typically found outside of cities. Aside from all of this, one chicken egg requires around 50 gallons of water to produce, so I'm sure that if you calculated the water needed to sustain non-vegan diets, the "cost" of upkeep for parks, golf courses, etc. would be negligible.
Not to mention that having low-density, sprawled-out communities literally inside forests (or deserts, or other biomes) is not good for the ecosystem either.
Living large in the burbs east of the Mississippi causes less environmental damage than even the most ascetic life imaginable west of the Mississippi. More water falls from the skies, for free, without pumping, than we know what to do with... In theory public parks and front yards in the west could be xeriscape-d but in practice they seem to mostly try to emulate golf courses in Florida leading to massive water use in a desert.
A walk in Hyde park gets you closer to "nature" but not really. It is just a brief escape from the concrete & asphalt.
Everyone might be surprised at how similar others are if they stopped trying to find and label differences.
If they take a step back and look around they will notice that this human-made "nature" which consumes massive amounts of water, to sustain the defined/controlled (human-made) beauty, and think to themselves "oh nature is perfect, oh how well I am protecting it!".
I don't know many city-dwellers that actually go for a hike on a real mountain to be in/with nature (and not some 5-star-hotel-private-beach or human-made green path).
