Deer-raising immigrants

Because of human gluttony, these eight animals have disappeared forever.

First, the dodo,

The dodo lives on an island in Africa and is isolated all the year round. Because there are no natural enemies on the island, the dodo has not evolved enough defense means, and its flight ability has gradually deteriorated, and its body has become bloated and slow to move. Living a carefree and well-fed life on the island, but all this changed with the arrival of foreign navigators. Around the17th century, early European navigators drifted with ocean currents to the island where dodos lived. They were surprised to find that this is an ideal plantation with fertile land and dense forests. Then they settled down on the island and named it Mauritius, which turned mauritius island into a farm. Subsequently, a large number of European immigrants came here, and the dodo became their leisure prey. In less than 200 years, dodos were hunted. Until now, there is a popular European proverb about dodos, which means "repeat the mistakes of dodos", which means going extinct.

Second, North American passenger pigeons.

Pigeons have become almost the most common food in the local area because of their large number and easy to catch. When pigeons cross the border, almost all residents will become hunters, and pigeons can be caught with nets. More professional hunters use more effective means, and a large number of traveling pigeons are transported to the city by train, becoming the cheapest food on the city table. 1909 Only three pigeons were found and kept in the zoo. 19 14 years, Martha, the last female pigeon on the earth, died.

Third, Irish deer.

Irish elk is considered to be the largest elk, famous for its huge size, with a shoulder height of 2 meters and a pair of huge horns, so it is also called giant deer. It used to have a wide range of activities, from Ireland to the east of Lake Baikal. The huge size did not give Irish deer an advantage, but became a burden. In the face of more flexible humans, the big horns of Irish deer can't play a role. Under the "efficient" hunting of human beings, this giant deer will soon become extinct.

Four, baiji dolphin

Baiji dolphin is a kind of freshwater whale, which lives on the earth for a long time, so it is called "living fossil in water" and has precious research value. Since ancient times, baiji has been very close to human beings. In ancient literature, the baiji dolphin is often known as the "goddess of the Yangtze River", because it can predict the weather changes and will churn on the water before the storm, so it inspires people to shore in time to avoid the rain. Baiji dolphin has poor eyesight, but it has a developed sonar system. It feeds on small and medium-sized fish and shrimp, and usually lives in pairs or dozens of small groups.

Verb (abbreviation of verb) great auk

Great auk's original name is actually Penguin. As early as the era of great navigation, the European expedition fleet traveled around the New World along the ocean coastline. In order to find the shortest route to Asia, an expedition fleet crossed the North Atlantic and arrived all the way near Greenland. Because of the long voyage in the ocean, the crew are tired of fish food and can't wait to rush to land to find new food. At this time, a large group of "penguins" are looking at these foreigners at a loss. They didn't panic, but approached human beings curiously. But it was taken away by the crew like a carrot. The crew were pleasantly surprised to find that these "penguins" were delicious, just like the turkeys in their hometown. After that, it was used as a supply point, and the only food source was great auk. 1844, in Iceland, three fishermen discovered two great auk. They ran after them and strangled them. At the same time, they crushed the last nest of eggs of this species, great auk. At this point, great auk, once ubiquitous, was finally eaten up. Later, people found the penguin in the Antarctic and gave it this name, but it was scientifically proved that they were completely different species, so they became "Penguin" and changed their name to great auk.

Six, European bison

The European bison is a species with a long history. It lived in India as early as 2 million years ago, then moved to the east, and settled in Europe about 250 thousand years ago and gradually flourished. The European bison is huge and is the ancestor of modern domestic cattle raising.

However, with the progress of human hunting skills, the defense means of European bison have been difficult to resist human hunting. By the13rd century, the distribution of European bison had been reduced to Poland, Lithuania, Transylvania and East Prussia. By 1564, the number of European bison was only 38, and the last recorded European bison died in Poland on 1627, and its skeleton was preserved in Stockholm museum.

Seven, manatees

Manatee is a large mammal that lives near the mouth of Bering Strait. It lives in water for a long time, with a body length of nearly 8 meters and a weight of about 3 tons. Because of its huge size, it has the metaphor of "the image in the sea".

Manatees live in groups and feed on seaweed. Although it is huge, it is very docile and has almost no defense ability. 174 1 year, the naturalist og steller first discovered this large manatee near the Asian coast of the Bering sea, but then Europeans flocked to it and soon opened it up as a new supply point. The source of supply is naturally manatees. Some sailors once described manatees as "very delicious, which reminds people of the taste of beef in their hometown". Manatees are gentle. Once a member is stabbed, other manatees will go to the rescue, but they will be rounded up instead. Only 27 years later, manatees will soon go from being discovered to extinction.

Eight, North American heather chicken,

Heather chicken is a common wild bird in the grasslands of North America, almost all over the coastal areas. Like a traveling pigeon, its tragedy began with the arrival of European colonists. People who are tired of eating pigeon welcome Heather chicken with delicious meat very much. If the pigeons are cheap goods in the stalls, then the Shima chicken is the "expensive material" in high-end restaurants. However, the breeding speed of Heather chicken obviously can't keep up with the demand of hunters. After a lot of hunting, Heather Chicken soon disappeared in most areas. Fortunately, a group of surviving heather chickens were found on an isolated island, and someone tried to breed them.
