if we do not buy animal fur,people will not kill wild animals any more的统一句

问题描述:

if we do not buy animal fur,people will not kill wild animals any more的统一句
_____ ______animal fur,people will not kill wild animals any more

如果只能用两空填,只有填Not buying / Without buying ,但这样we这个逻辑主语没有表达出来,句意就有点出入了,限制了空格了吗?
