The DoDo bird is a flightless bird that is only fat in Mauritius. It has a fat body and a huge beak.　　In the late 16th century, European colonizers came to Mauritius. The DoDo bird, which cannot fly or run fast, soon became the main source of food for the Europeans when they came to the island. People began to hunt and kill the poor DoDo birds indiscriminately, sometimes by the thousands to tens of thousands per day. As a result of the overkill, there were soon fewer and fewer DoDo birds on the island, and after the last DoDo bird was brutally killed in 1681, it was never seen again on earth, except in museum pictures. The manatee is a large aquatic herbivorous mammal. It is plump and slow-moving, with pulpy forelimbs and hind limbs that have completely disappeared. It fed mainly on plants in shallow seas and bays and in slow-moving rivers. In the early days, because the manatee not only meat is tender and flavorful, the skin can also make wear-resistant leather, and even the ribs can be used as a substitute for ivory, the whole body is a treasure. This is to lead to it by human beings a lot of hunting and killing. 1973, the United States and other North American and Latin American countries, have put it on the list of endangered animals, to protect. But the manatee is still decreasing year by year, in addition to man-made poaching, unintentional killing is also very serious. Such as the United States, Florida coast, due to water pollution, red tides occur year after year, the manatee is also dead year after year. Last year, 304 heads died, exceeding the record high of 206 annual deaths set in 1990. Now we have a hard time seeing such delicious food in recipes.
