This is an outlandish threat that shouldn't deter Germany from banning the import of hunting trophies. The unethical organizers of these hunting trips are the only ones who benefit from these activities, not the poor local residents or even the hunting authorities. Botswana shouldn't do anything to jeopardize its conservation achievements and should instead work with Germany on ways to protect its biodiversity.
His offer may sound bizarre, but it has a serious background, so Masisi's intentions are admirable. An ill-considered import ban would penalize countries like Botswana and undermine their immense wildlife conservation efforts. The so-called "developed" countries should first worry about their own fauna, abandon their neo-colonial attitude, and take local concerns seriously.
