At first, an zoo in England was willing to receipt Marius, but as there were several giraffes sharing the similar gene-pool with Marius. The number of giraffes was already fulfilled in that England zoo already. 

當時，英格蘭有動物園表示願意接收Marius，但是該動物園已經有Marius血緣相近的兄弟，整體而言和Marius相近的長頸鹿數量已經足夠。

At the time, [Yours is not wrong, just to show you another way] there was a zoo in England expressed interest to accept Marius.  However, several giraffes there had the same genetic pool. Overall, there were enough of Marius type of giraffes.

Holst pointed out that, in the past, zoos would look forward to the special species. However, at present, zoos are prefer the variable species. Generally, the specie of Marius was not concerned about the extinction.
Holst指出，過去動物園會爭取擁有特定物種，但現在各動物園都試圖追求多元物種。綜觀整個動物園的情況，Marius這個長頸鹿的品種，目前沒有面臨滅絕的可能。

Holst pointed out that in the past, zoos will look for a particular species but nowadays, diversity is the preference.  The species-type that Marius belonged to is not currently endangered.

As feeding lion by the body of Marius, in Holst's opinion, is a part of nature. "In reality, the relationship between animals is far way from the likelihood of DisneyLand."
至於讓Marius的屍體去餵食獅子，Holst認為，這是自然界的一部份。"在自然界之中，動物和動物之間不像迪士尼卡通。"

As for feeding the carcass of Marius to lions, Holst considers it as part of nature. "In the natural world, animals are not Disneyfied characters."

Why kill a healthy giraffe to feed a lion? The head zookeeper said, "Nature is not like the cartoons of Disney"

A two-year-old healthy giraffe, Marius, was killed and dismembered in public as for feeding a lion in an zoo in Denmark, in February 2014. In terms of the overwhelming public echoes of such decision, the superiors of the zoo, Bengt Holst, even was threatened by his death.
2014年2月，丹麥動物園殺死了一隻兩歲的健康長頸鹿Marius，並將其屍體公開餵獅子。這樣的決定，引起各界不同的聲音，丹麥動物園的園長Bengt Holst還因此收到不同的死亡威脅。

In Feburary 2014, a two year old giraffe named Marius was killed in a Denmark zoo and publicly had its carcass fed to the lion.  This decision led to a disarray of discontent from various quarters. The head zookeeper, Bengt Holst was thus threatened with death.

Currently, he had a interview with Stern Magazine. During the interview, he talked about why he had made that decision back in those very days and the relationship between human beings and animals.
最近，他接受德國《星辰（Stern）》雜誌的專訪，談及他當時的考量和決定、以及人類和動物之間的關係。
Recently, he was interviewed by the German magazine, Stern.  In the interview, he discussed the then consideration, the decision and relationship between mankind and animals.

The reason for euthanising Marius was since the strong fight between Marius, a two-year-old giraffe, and his father occurred. Naturally, it was the period for every giraffe to become independent. Therefore, the zoo had realised that it was time to spot an new home for Marius.
當時決定要讓Marius安樂死的原因是，二歲的Marius開始與牠的父親有強烈的對決。在自然界中，這樣的年齡通常已經自立。丹麥動物園開始意識到，有為Marius尋找新家的必要。
The reason at that time was to let the Marius be euthanasized.  At the age of two, it started to challenge its/his father.  In the wild, this is how independence is established.
