Koala
May 23, 2015 16:56
There are a lot of zoos in Japan, but there are few koalas in the zoos.
One of the reason is that the koala's feed costs is very expensive.
Since it is difficult to get eucalypti that is the only food of koala in Japan, it costs about 10 to 20 million yen per head per year.
Also, the eucalyptus contains toxins of potassium cyanide type.
A koala's very long cecum has an enzyme that degrades the toxins, but ethanol emitted by chewing will paralyze koala's nerve and get him to sleep.
In the ranking of long sleep animals, koala that sleeps 22 hours per day is the top, while sloth that sleeps 20 hours per day is the second.

日本に動物園は沢山ありますが、コアラに会える動物園は多くありません。
その理由の一つに、コアラの餌代の高さがあります。
日本ではコアラの唯一の餌であるユーカリの確保が難しく、コアラの餌代は一頭当たり年間1000～2000万円かかります。
また、ユーカリには青酸カリ系の毒素が含まれます。
コアラの非常に長い盲腸には毒素を分解する酵素がありますが、咀嚼によって出たエタノールが神経を麻痺させ、睡眠を誘うと言われています。
睡眠時間の長い動物ランキングで、コアラは1日22時間となっており、20時間のナマケモノを差し置いて一位です。

That sounds strange. Considering Australia isn't far fron Japan.

Yeah, it could sound strange. I also thought so. However, koala is known as a gourmet, e.g., they eat only shoots of eucalyptus, and the kind of eucalyptus that they eat is different depending on koala. Furthermore, they eat a large amount of it. We need prepare cultivation dedicated farmers for many kinds of eucalyptus, tough, it's difficult to grow them in Japan (while it grows naturally in Australia). For these reasons, it seems to take a large amount of cost.

I heard we had done that, but it took more money.

コアラは"新鮮な"ユーカリの新芽した食べません。以前は毎日、何種類ものユーカリを大量に空輸していました。お金がかかるのは仕方ないと思います。

なるほど。では、日本人はコアラを見る為に、オーストラリアへ旅行た方がいいですね。確かに、遠いではありませんね。

そうですね。無理して日本で育てるよりも、そのほうが良いかもしれません。私もオーストラリアの雄大な自然の中でコアラを見たいです。

"The cost is very expensive" is incorrect, http://www.italki.com/question/126782 here is why.

Here in English よって来たる can be understood as a cause or a source of something, "assimilated" means he gets ethanol into its body.
