Most nations have at least one type of food that people from other countries think is unusual or unethical（不道德的）to eat. In France, people eat horse meat and frog legs. In South Korea and parts of China, restaurants serve dog meat. And in Australia, it’s common to cook kangaroo meat on the barbecue and use emu（鸸鹋）eggs to make pancakes.

The kangaroo and emu are native to Australia. Both animals are important to the national image of Australia and appear on the Australian coat of arms. They’re also central figures in the history of the indigenous（土生土长的）Australian Aboriginals（土著人）. However, Aboriginal tribes still hunt these animals for their meat, fur and fat.

Today, Australian people continue to eat these animals. One of the reasons people eat kangaroo meat is that it’s high in protein and low in fat, so eating kangaroo is a good option for anyone on a diet. It’s also cheaper to eat kangaroo meat than other red meats. Because of this, a lot of university students choose to buy kangaroo meat. BBC News also reported that Australian scientists believe that eating kangaroo meat is good for the environment--kangaroos have different digestive systems than cows and sheep, meaning they produce less methane（甲烷），the second biggest contributor to global warming.

While emu meat is high in iron and vitamin C, most people don’t think it tastes good. For this reason, they prefer emu eggs. One egg is large enough to make seven omelettes（煎蛋）. And while it’s illegal to collect emu eggs from the wild, they can be bought from emu farms. Rather than cracking the beautiful dark shell, it’s better to drain it by putting a small hole at each end and blowing. Afterwards, you can even carve a design into the eggshell.
