There are many kangaroos in Australia, but why not in China?

Blue is the existing distribution area of marsupials, and its distribution range is very wide. Maybe many people don't know the world map from this perspective. On the far left is Australia, and on his right are New Guinea, Sulawesi and many other islands. On the far right is the Antarctic continent, on the upper left is the South American continent, followed by the North American continent.

Only a few marsupial species are suitable for them to breed in an independent activity area like Australia, and the natural enemies in this area have not absolutely hunted them, nor have they been eliminated by natural enemies.

This may be due to the drift of the continental plate. People found marsupials fossils in South America, which shows that marsupials are also distributed on the mainland. Later, Australia separated from the mainland due to the drift of the continental plate and became an ocean island. Marsupials can breed in Australia because there is no natural enemy interference. However, marsupials on the mainland gradually disappeared in the long river of history because of their picky lifestyles and low reproductive rate.

There are many kangaroos in Australia. It doesn't matter if you are killed on the road. There will be a special body collection team to collect it. Ordinary kangaroos should not be considered as protected animals.

Being in a "lonely continent" surrounded by the sea, there are few indigenous people living here. According to Australia's previous statistics, the total number of Australian aborigines is about 420,000, accounting for about 2.7%. As a world-famous "immigrant" country, its population mainly depends on immigrants.

Although Australia is a penal colony, it has become one of the developed democratic countries in the world. Does this fully show that a good national system can change bad races and create a better country?

In addition to kangaroo meat products everywhere in supermarkets, warning signs of "Beware of Kangaroos" can be seen everywhere on highways and expressways in Australia, and kangaroos dragged to the side of the road and killed by cars will be seen every few kilometers. When opening a business road, I often see sparkling eyes on both sides of the road. They are all kangaroos. What I fear most is that a kangaroo suddenly runs into the road.
