I don't see the lack of hunters being the problem some imagine it to be. In Australia, hunter numbers went into decline for a while, but that has changed significantly over the last few years. If I went to the range back then I would look around and see only grey and balding heads. Many clubs were on their last legs as the membership passed away. Today however, the ranges are full. In particular large numbers of younger shooters and families. Shooter licences, hunting licences are at record levels. So too is the number of hunters who keen to try the safari experience and global hunting. I think what happened is that the post Vietnam generation were brainwashed against guns and hunting and numbers decreased. However a new generation has grown up and rejected that. They have found shooting and hunting to be fun and are taking it up wholeheartedly. Of course if you watch TV, then you wouldn't see this. All the media types are still adherents to the old anti hunting propaganda. But really, who takes notice of anything they say? All in all I think the future is looking better than it has for decades.
As to the risk of the new US Administration taking action against hunting. I consider that to be quite high. Not because they care, but because its easy. Compared to many in their party, Biden and Harris are comparatively conservative (note: I said compared to the others in their party!). To get where they are, they have had to make a lot of promises to the assorted crazies. Virtually none of which they will keep. However it will be easy to throw the leftists a few token bones. Unfortunately, those 'bones' are likely to be anti-hunting/anti-shooting measures, all designed purely to fob off those who got them into power. I hope I'm wrong.
