It¡¯s Friday afternoon at the Venetian Macao hotel¡¯s Portofino restaurant, and on the terrace a handful of chefs in white uniforms are preparing the casino hub¡¯s famous pork chop bun for waiting guests.

In a region where pork is king ¡ª it is the favored meat in most dishes ¡ª switching diets to a tasty vegetable substitute could be a major way to curb climate change, experts say.
