To me one of the biggest problems is that baby rabbits sitting in a pet shop are very cute. Undeniably so. It is very very easy for people to make an impulse buy without any thinking it through. Every time I go to my pet shop/garden centre for supplies I want to take every cute sad little bunny there straight home with me. I don't but the impulse is there. It's WAY too easy to get a rabbit on a whim with no thought of the consequences.
The other huge problem is of course education, it is practically impossible - even if you want to and are trying hard - to get the right information about how rabbits should be kept and what sort of animals they are. Someone needs to write a few good books and get them into petshops and bookshops to replace the generally rubbishy ones that are sold as 'facts' about how to keep rabbits.
The worst of all though is stupid and irresponsible people letting their rabbits have unlimited litters because they don't see any problem with it. This isn't about breeding in the way that responsible breeders concentrating on one or two breeds are doing it, it's about the ones who will stick any two rabbits together and enjoy the babies before selling them to pet shops, snake food, releasing into the wild whatever and to me it's the way I see it happen most. It makes me fume!!!!
As Tamsin pointed out, rescues are a symptom not the solution to the problem. I have eight rabbits at the moment. With the exception of two of them they were all rescued, but directly, rather than through a rescue. I'm sure I'm not alone in being part of another statistic, people who rescue without being a rescue (though one day I'll probably end up as one)
Getting back to education, I also think that if more people knew what their rabbit was capable of they wouldn't get so easily bored with it. Most people have absolutely no idea of how interesting, lovable and funny that rabbit stuck in a hutch at the end of the garden could be if given any chance at all
