I never thought about this until I started reading on carnivorous plants. A lot of nurseries sell exotic plants that are legally or sometimes illegally taken directly from their natural habitat such that it is environmenally unsound. This is particularly true of exotic plants. I like to grow succulents and want to get some more venus fly traps (let's not debate the ethics of feeding them!) I'm afraid of them being irresponsibly obtained.
I found links to environmentally conscious sellers of carnivorous plants, but have not been able to find anything on this issue for general housplants/shrubs, etc.
Has anyone else researched this issue at all?
