번역 - 스페인어-간이화된 중국어 - cuida tu tierra, protege tu familia

The "simplified chinese" tranlsation is actually not correct

Should take a look at the English translation which is exact :

Protect your <<land>>, not your earth (地球）.
and then , protect your <<familly>>, and not your homeland (家園）.

It should be, 保衛你的家園 (land, homeland, home ground, in an extension the land could also be, your country etc) 保護你的家庭 (familly)

爱土保家？
