This sounds similar to the UK. I've heard it called an ecological desert and almost everywhere you go feels very much like paths through some meadow or woods to take a stroll through. I would hope it's not like this everywhere since they still have a few large natural parks, but from the little I've seen, it sounds like what you're describing.

We act as if we completely own the world. As if it is our personal theme park to have fun in, instead of actual wilderness with biodiversity and wild animals and stuff.

Yep, the hubris and arrogance of westerners in their relationship to nature is staggering. My coworkers are some of the most disrespectful people towards the environment I've ever seen. Drinking water from plastic bottles instead of filling up their glasses from the water cooler because it takes fewer trips to the kitchen, and throwing them in the nearest trash can instead of walking an extra 30 seconds to the recycling. I know in the grand scheme of things this isn't what's causing the climate catastrophe, but still I think it speaks volumes about these people
