What s the biggest threat we now have facing us and the planet?
I would say over population, lack of resources (Namely Oil), and laws for just about everything from breathing air to sleeping.
There was a time when we had far more freedom to do as we wanted than we currently have now. You could go to the woods and camp, now you need a permit and you have to pack out your waste. (ALL WASTE! Yup, 1 & 2 are included).
As the population increases, resources dwindle and freedom to be free is dramatically reduced. Hell at one point I bet many of you could simply walk out side at any hour and take a whiz, but to do that now you'd more than likely end up on some survalence video.
What used to take 20 minutes to drive now takes an hour with all the traffic, new signals, road revisions, etc. The more people we have, the less mobility we enjoy, hence the less real freedom we have.
Only 20 years ago it was ok hunt, now it is impossible to find an area. 10 year ago we could ride our dirt bikes in the woods, now that area is all houses and closed off for logging. 5 years ago we could ride our quads on the beach, now that is being closed to preserve the sand.
What used to be free camping is now reservation only.
I know that many call this evolution, but I call it what it is, a sincere and continuing threat to the freedom and enjoyment of life.
