介于山羊會吃一切綠色的東西，這一點似乎有些奇怪。不過茶樹并不像看上去那樣毫無設防。
Tea leaves are loaded with bitter chemicals designed to repel browsing animals.
茶葉中存在刺激性的化學成分以驅走啃食的動物。
It works on the goats, who leave the tea untouched and instead eat up the weeds, fertilising the tea plants with their droppings.
這對山羊很有效，它們只是吃光茶樹外的雜草，它們的糞便恰好茶樹供給了養分。
The surprise is that we humans should find the same bitter chemical cocktail utterly irresistible.
令人驚訝的是，我們人類卻為這種苦澀的化學混合物心醉神迷。
