It's not just the Netherlands, this is happening in Italy as well. Part of it is just the natural consequence of people having abandoned the countryside and mountains for the cities. But we certainly forgot what it means to not be the only apex predator around- we used to be able to roam around without a fear in the world like we owned the fucking place (we did). It's nice to have a wild ecosystem around but we probably forgot what it means to have around beings that are... unaligned with us.
