应对气候变化：让宠物狗改吃虫子

你有没有因为环保人士把气候变化归咎于自家的宠物狗而感到烦恼不已？别怕，现在只要给你家 “汪汪” 喂用黑色兵蝇做成的狗粮，不用喂什么巴西牛肉，它也能长得胖胖的。一家宠物食品制造商说，他们的一款新产品中含有 40% 的兵蝇幼虫。

It's estimated that pets consume around 20% of the world's meat. That's led some owners to worry about the impact of their dog on the planet, as meat production is a major source of greenhouse gases.

据估计，宠物吃掉全球20%的肉类。这使一些宠物主人开始担心自家狗给地球造成的影响，因为肉类生产是温室气体的主要来源。

Vegan dog foods are on sale but environmentalist owners wanting to treat their pet to animal protein can now turn to a Dutch product called Yora. The grubs of black soldier flies make up 40% of it.

纯素狗粮已有售，但那些注重环保的、想给宠物吃动物蛋白的狗主人们现在可以转向一款叫作 Yora 的荷兰产品。这个产品中含40% 的黑色兵蝇幼虫。

Insects do use a fraction of the water and land of cattle. So this looks an environmental boon. But it's not quite so simple. Normal dog food is mostly offal, so dogs are typically eating meat that humans have rejected. To really make an environmental difference, owners would need to join their dogs in cutting down on the meat.

昆虫的用水和用地面积是牛所用的极小的一部分。所以这款产品看来对环境大有裨益。但事情并没有那么简单。普通狗粮的原料大多是动物下水，所以狗吃的通常是人类不要的肉类。要想对环境做出实质性改变，狗主人需要和他们的狗一起少吃肉。
