Let them take care of themselves.

- 彼らのことは放っておけよ。
- あいつらのことは放っときな。

The trouble is that they only think of themselves.

困ったことに、彼らは自分たちのことしか考えません。

銭厘を大切にすれば大金はおのずとたまる。

Instead, they live alone as long as they are able to take care of themselves.

自分が自分の面倒を見られる限りは自分たちだけで暮らす。

[Richard] They can use these little pincers to hold bits of coral rubble and algae on top of themselves to help camouflage their presence.

管足(かんそく)でサンゴ片や藻をつかみ 体を覆って カモフラージュする

In the countryside, the breaths of the grass, the trees, and the rocks have the foul smell of humans. They call to me from all directions, and they cling to me. But in the city, even the passengers of a jam-packed train are as quiet as pebbles on the riverbed, and everyone is only thinking of themselves.

田舎では草も木も石も人間くさい呼吸をして四方から私に話しかけ私に取りすがるが、都会ではぎっしり詰まった満員電車の乗客でも川原の石ころどうしのように黙ってめいめいが自分の事を考えている。
