Rabbit invasion in Australia


Everything starts in 1859 when an english Colomb by the name of Tomas Austin moved to Australia and release in the meantime 12 couples of wild rabbits for hunting. What he didn't think was that the rabbits would reproduce quickly:

each couple of rabbits can have up to 5 reaches a year. Each reaches can have up to 12 children wich make 60 rabbits multiplied by the 12 first wich make 720 rabbits only the first year! just think about multipling this number every year wich can reach enormous amount of rabbits!

To come has end of the disaster, everyways are opened: hunting, traps, poison. But nothing can stop them. Desperate situations call for desperate measures, authorties then decided to build a great fence in
order to keep the rabbits in an area twice as big as France. It then becomes the biggest fence in the world never built. Unfortunatly, it took too much time and the rabbits crossed.
A second much smaller fence was built then a third to become a total of 3000km of fence, or 3 times France. unfortunalty again, the fences where not enough to stop the mutliplied rabbits. Another idea took place: fox import but unlike we think, foxes are more likely to hunt little animals becauses rabbits are too fast. Creating once again a big echo-system failure.

It is in the 50's that scientists found a radical way to kill every bunny: the Myxomatosis virus, deadly for them. It was effective in the first place, 90% of all rabbits were killed but the 10% left built up immunity against it, making it weak in 5 years. Rabbits reproduce again more and stronger.

Continuing in the same way, scientists introduced more viruses. Once again, bunny were immunised and stronger than never before...

Australians found out the virus killed every other animals and decided to stop everything in order to slow down the reproduction of rabbits. Today, they are concidered as harmful animals like, foxes, cats or camels.

Fortunatly, we now are able to controle in a more efficient way reproduction of rabbits.

Sofball


Softball-STACK1Softball is a variant of baseball played with a larger ball on a smaller field. It was invented in 1887 in Chicago as an indoor game. It was at various times called indoor baseballThere are three types of softball:

slow-pitch softball, the ball, which can measure either 11 or 12 inches in circumference depending on the age and league, must arch on its path to the batter, and there are 10 players on the field at once.

Fast-pitch: the pitch is fast, there are nine players on the field at one time, and bunting and stealing are permitted.

Modified softball restricts the windmill windup of the pitcher, although the pitcher is allowed to throw as hard as possible with the restricted back swing. Softball rules vary somewhat from those of baseball. Two major differences are that the ball must be pitched underhand—from 46 ft (14 m) for men or 43 ft (13.1 m)for women as compared with 60.5 ft (18.4 m) in baseball—and that seven innings instead of nine constitute a regulation game.

Tasmania


Wine-Glass-Bay-Tasmania-low-resTasmania is an island state located 240 km to the south of the Australia mainland.

The island have been occupied by Aboriginals for 40,000 years before British colonisation.
It is thought Tasmanian Aboriginals were separated from the mainland Aboriginal groups about 10,000 years ago when the sea rose to form Bass Strait.
The Aboriginal population was estimated to have been between 3,000 and 7,000 at the time of colonisation, but was almost wiped out within 30 years by a
combination of violent guerrilla conflict with settlers known as the "Black War", intertribal conflict, and from the late 1820s, the spread of infectious diseases to which they had no immunity. 

The state was officialy created in 1803 as a penal settlement of the British Empire to prevent claims to the land by the First French Empire during the Napoleonic War.

Possum


default-1464364145-86-man-talks-to-possum-and-the-possum-talks-backThe possum has a thick, bushy tail, a pointed snout and long fox-like ears for two general colour forms, grey and black
Possums looks like big rats, they live in the trees or in the attics because they live only by night and frequently early morning.
They can be found all across New Zealand

Threat:
The damage to native forests can be seen all too clearly in many areas. Possums ignore old leaves and select the best new growth
One of the things that opossums will do in order to avoid a confrontation with humans is play dead.
